It would be tempting to say that this picture is a metaphor for these COVID19 times, but actually that would be quite crass. While all the restriction have been in place I’ve been determined to have some creative output and this is part of it. Over the last week I’ve been making myself go out in the evening to photograph. To make things a little more interesting I decided to impose a restrictions on myself. In this case I would use a focal length that I don’t particularity like (50mm) and an old vintage lens on a digital camera.I’ve walked past this wreck many times with the dog and really not taken any notice of it. Well on this particular evening the local farmers had been burning off and the smoke in the air was creating a nice warm light as the setting sun shone through it. I thought that the rust of the car complemented the warm lighting.

Backyard Birds 2

Welllllllll…not strictly true. This Nankeen Kestrel was on the power pole on the nature strip in front of our house. Another metre and it would have been in the front garden so I’m claiming it. They often perch there in the cooler months to either observe the field opposite for small animals or to eat the small animal they’ve just caught. This one was running an observation post.

Backyard Birds

Well it seems that the COVID-19 restrictions have been in place for an age. Here in Western Australia the social distancing requirements aren’t as strict as some places, but we still aren’t able to go where we want and do what we want. It makes me more appreciative of what my parents went through growing up in the Great Depression and then after that the Second World War. But anyway to keep myself from going totally mad I’ve been working on a few projects. This one is to document all the birds that come into our backyard. I’ve not got them all by any means. Some are very elusive and just don’t want their photos taken for some reason. Can’t imagine why. Here is a selection form the last couple of weeks.

Well that’s it for this week. Stay safe, keep positive and try and keep busy.

Keep Calm


This last few months have been particularly difficult in the light of climate change induced bushfires here in Australia and now the spread of the Coronavirus (COVID 19). It would in the light of compulsory lockdowns, quarantines and restrictions on social gatherings and travel easy to be filled with dread and let feelings of hopelessness pervade our lives. I myself have had further restrictions imposed as I’m in the process of recovering from spinal surgery and am fighting off the temptation of feeling sorry for myself and collapsing in a heap.

There is an antidote to this. Firstly instead of just being passive and feeding our psyches with all the negative news we can find in the media endeavour to do something creative. Creativity is important, it feeds the soul, gives a sense of achievement and allows you to express yourself. All of this has a positive effect on your psychological well being. It doesn’t matter what it is – paint, draw, knit, cook, write, photograph, sing. Although singing could be problematic depending upon your living arrangements and how well you can sing. My partner has issued me with an ultimatum; if I sing Bohemian Rhapsody at full volume in my usual tone deaf manner then lockdown or not I will be looking for alternative accommodation which I think is a little harsh. Secondly reconnect with nature. This one could be a bit hard depending on what the local authorities are imposing, but it can be done. If confined to the house take time out in the garden, encourage wildlife to come into the garden and watch them. Plant things and watch them grow. If possible go a walk in the park or woods (maintaining correct social distancing of course), go bird watching, fungi spotting it doesn’t really matter. Bonus points if you can combine this with doing some creative as this will allow you to enter a flow state. Sounds poncey but “it is the mental state in which a person performing an activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. In essence, flow is characterized by the complete absorption in what one does, and a resulting transformation in one’s sense of time” (Mihály Csíkszentmihályi, 1975). The benefits of this are that intense and focused concentration on the present moment that you become so totally engrossed in the experience to the extent that other needs or concerns become negligible and this makes you feel in control over a situation. Do this a few times a week and your mood will lift.

I’ve taken my own advice this week. As I said I’ve been laid up at home and not doing much so I hauled my carcass down to the Avon River a couple of times to photograph some birds in the dawn light. It was well worth it. Stalking birds and photographing them required too much concentration and I was able to forget about my own circumstances and the worries of the world and just enjoy being in the moment. It was so enjoyable that I’m going to get out and do some more over the next week.

Optical Antithesis


A review of the Sigma 16mm f/1.4 DC DN lens for m4/3

 

 

 

The Sigma 16mm f1.4 shown mounted to an Oympus OMD EM1 mk 1 which is one of the larger m4/3 cameras.

 

I’ve said many times on this blog that my favourite focal length is 35mm (35mm equivalent) which give a diagonal angle of view of 63.4º To me it is a relaxing normal view, I find 50mm a bit too tight and 28mm a bit too “loose”. So when I migrated from so-called full frame to micro four thirds in 2010 one of the first lenses I bought was the Olympus m.Zuiko 17mm f2.8 pancake lens. Actually at the time there were only three lenses in the system the 17mm, a 14-42mm kit lens and the 40-150 telephoto kit zoom and I ended up getting them all.

 

Olympus m.Zuiko 17mm f2.8 shown on an EP5. The lens was the first prime introduced for the Olympus’ m4/3 system.

 

The 17mm was equivalent to 34mm in in full frame terms and has a diagonal angle of view of 65º, so close enough as not to make any real difference. It wasn’t a well received lens despite being what initial advocates of the micro four thirds said they wanted – pancake lenses. It’s slow maximum aperture of f2.8, slow and noisey auto focus combined with less than stellar optical performance put many people off and they went for the much more expensive Panasonic 20mm f1.7 which had the virtues of being optically better, and having a faster maximum aperture. It still wasn’t great in the AF department though. But hey these were the early days of mirrorless technology and AF systems were not very quick and accurate then. But anyways I got the Olympus in a kit with my Olympus EP2 and I actually loved it. I could slip it mounted to the EP2 in my pocket which made it a great stealth camera combination and I used it to shoot my TransPerth-Transhumance project. I still use the lens today, mainly on my EP5. The area where I felt it was absolutely hopeless was video. The AF was too slow, too noisy (think angry wasp stuck in a jar) and I wanted a bit more subject isolation than the f2.8 aperture could give.

 

The Sigma 16mm f1.4 compared to the Olympus 17mm f2.8, 25mm f.1.8 and the 45mm f1.9.

 

The Sigma 16mm f1.4 is a physically large lens. Here it is shown with the Olympus 12-40mm f2.8 and 75-300 f4-6.3 zoom lenses.

 

So fast forward a few years and I’m shooting more and more video and I decide to get myself a better 17mm lens. In the intervening years Olympus had produced the very favourably received 17mm f1.8 and the eye-wateringly expensive f1.2 version. Panasonic had also come to the party with their Panasonic Leica Summilux 15mm f/1.7 lens. In fact I went to my local (if you can call 110Km away local) camera dealer to buy this lens and it was always out of stock which made me want it even more. But in the end I went for an outlier in the form of the Sigma 16mm f/1.4 DC DN lens. The reasons being that f1.4 is faster than f1.9, it was cheaper than the f1.2 and the difference between f1.2 and f1.4 is slight, and my dealer had it in stock. So what makes it and outlier? Well to put it bluntly it’s bloody huge. It has a 67mm ⌀ filter thread which compares to 37mm for the Olympus 17mm f2.8. It is bigger than the Olympus 12-40mm f2.8 and the Panasonic Leica 8-18mm f2.8-4 while being only a little shorter than the Olympus 75-300mm f4.8-6.7. The 16mm focal length equates to 32mm on full frame with a diagonal angle of view 68.1º so is a bit wider, but when used with the Panasonic G85 for 4K video this isn’t much of a problem as the camera crops in slightly. So how come this lens is so lardy I hear you all ask. Well this lens wasn’t designed for micro four thirds, it was initially designed for the Sony 6000 series cameras with an APS sized sensor where it equates to being a 24mm in full frame terms. To get a wide angle lens that’s fast and a good optical performance means lots of glass and glass is heavy, and this lens is large and heavy for APS format cameras. To get some additional return on their investment Sigma decided to offer the lens in micro four thirds mount hence it seeming a funny focal length and being bigger than necessary.

In the hand the Sigma 16mm feels very dense and substantial. The lens body is made out of what Sigma calls a Thermally Stable Composite (TSC) which is substantially stronger than conventional polycarbonates while having similar thermal expansion properties to aluminium. The lens mount is made of chromium plated brass which should ensure a long life. The Sigma 16mm is advertised as being dust and splash proof but on closer reading of Sigma’s spec sheet there is only one seal and that is at the lens mount. The lens comes with a bayonet mount petal lens hood which has a ribbed grip to make attaching and detaching easier. While it is good that the lens comes with a hood it’s not the best implementation and feels quite insubstantial and can be fiddly to attach as it can foul and not lock home. There is a ribbed rubber focus ring of the fly by wire type – it feels smooth and easy to use. There are no other controls or switches which means if you want to switch between AF and manual focus you will have to use the camera controls for that.

 

 

The Sigma 16mm has an optical construction of 16 elements in 13 groups with 3 FLD (“F” Low Dispersion) glass elements, which offers performance equivalent to fluorite which exhibits less chromatic aberration than those utilising a traditional flint glass. There are 2 SLD (Special Low Dispersion) glass elements which also help to minimise chromatic aberration and 2 ASPH moulded glass aspherical elements which work to reduce optical aberrations. According to Sigma’s website the ASPH elements are polished with a tolerance of under 10 nanometers or 0.000001 millimetres which according to Sigma reduces onion ring bokeh.


Performance

100 % crops showing lens performance wide open and then at the best performing aperture.

 

In terms of autofocus the stepping motor is fast and accurate and very smooth when shooting video. I tested the lens on the OMD EM1 mk ii which has on sensor phase detect AF and on the Panasonic G85 which uses DFD technology – a variant of contrast detect auto focus that requires the lens to provide a profile to the camera to ensure fast and accurate AF. The Sigma does not have such a profile as these are limited at present to only Panasonic’s own lenses. Despite that there were no problems and I could detect no discernible difference between the Olympus and the Panasonic. The only downside in the AF department is that I can’t use the Pro Capture Low setting which gives up to 18 fps with auto exposure and AF tracking. This is no fault of Sigma’s as the option is only available with Olympus lenses.

 

 

Optically – well straight from the get go the Sigma is impressively sharp wide open corner to corner. The performance improves slightly (and it is only visible on my 4K screen at 300%) as you stop down. Diffraction sets in at f16 and this does soften the image. In terms of chromatic aberration, well wide open in high contrast situations it is apparent albeit slight and it is easy to correct in post. The lens is reasonably resistant to flare – but if you have a specular light source in the frame you will experience some veiled flare and ghosting. If you turn off the built in lens profile you can observe a slight barrel distortion, but switch on the profile and it is not visible. The bokeh balls this lens produces are more or less round when shooting wide open even at the edges of the frame and the transitions are nice and smooth. There is some onion ring bokeh which is the result of using moulded aspherical lens.Vignetting is not a problem and is very slight in the region of 1/2 stop.

 

Chromatic aberration is quite apparent on this lens. It is also quite prone to flare even when using the included lens hood.

 


Verdict

This slideshow requires JavaScript.

 

Being designed to have an image circle much larger than micro four thirds requires means that you are using the best performing part of the lens and this really shows. Just for giggles I compared the Sigma with my old Olympus. The Olympus is noticeably soft in the corners at all apertures and just average in the centre. It suffers badly from chromatic aberration. Vignetting is very apparent, in excess of 1 stop in the corners with the lens profile switched on and getting on for 2 stops when switched off. Physically, optically and figuratively the Sigma stands head and shoulders above the little Olympus. The only area where the Olympus wins out is its small size and that is why I’ll continue to use it when I want something small and compact. For every other occasion I’m reaching for the Sigma. The knock on effect is that I’m seriously wondering about replacing my Olympus 45mm f1.8 with the Sigma 56mm f1.4.

New Victoria Dam

The ubiquitous New Holland Honeyeater (Phylidonyris novaehollandiae), New Victoria Dam, Korung National Park, Western Australia.

Over the last few days my FaceBook feed has been seeing some seriously tasty bird photos from one of the groups that I belong to. The photos all come from one area  – New Victoria Dam which is 30Km east of Perth on the Darling Range in Korung National Park. So when the Beloved Significant Other (BSO) announced she was competing in a croquet competition at a location just 20 minutes drive away I immediately volunteered myself as driver.

 

 

 

 

There are two starting points to the walk and which you choose will largely depend upon when you visit. If you visit outside of office hours Monday to Friday or anytime at the weekend then y ou have to use the upper carpark as your start point as the access road is shut. During office hours you can drive down to the lower carpark keeping in mind that if stay till after 5pm then you won’t be able to drive out. I started at the upper carpark which only adds 800m each way to the walk. The walk consists of a 7Km round trip down past the New Victoria Dam to the Old Victoria dam wall and the garden and picnic area. There used to be a path through the trees at the edge of the road but it has become quite overgrown and indistinct so you are best walking along the access road. As you walk down the road on your left is the  gravesite of Francis Weston who died in 1876 aged two days, his parents lived in the timber workers settlement at Bickley. When you get to the lower carpark walk through it and then follow the trail markers. After walking through the forest you come to New Victoria Dam. Walk down the steps and at the bottom turn right onto the road and walk down to the remains of the Old Victoria Dam.

The steps down to the New Victoria Dam.

 

The original dam was built in 1891 and pumped water via pipelines to Kings Park and a reservoir there on Mount Eliza. The dam became the first permanent water source for Perth and was operated by the private City of Perth Waterworks Company. As the water catchment area took in agricultural land and timber settlements there were fears that it would be polluted by raw sewage and excrement from livestock. Between 1895 and 1900 typhoid broke out in Perth and 425 people died. The water was tested and found to be contaminated so the government took control and made changes to prevent re-occurrence. By 1988 the concrete structure was beginning to degrade to such an extent it could no longer be repaired so in 1990 work on the new dam commenced and because of the use of roller compacted concrete it was completed by the following year. It can hold 9.5 million kilo-litres and is used to supply drinking water to Kalamunda and Lesmurdie.

In the lee of the old dam there is a grassed picnic area and toilets. Thickets of ti-tree and one-sided bottlebrush or claw flower have been planted and the thick vegetation along the creek line provides dense cover for a number of bird species. On this trip I used the picnic gazebo as an impromptu bird hide and spent a couple of hours watching the various birds feed and drink. I saw  red-eared firetails, mistletoe birds, splendid fairy wrens, western spinebills, new holland honeyeaters, white faced herons and rosellas. The dam spillway feeds water to the pond and creek that provides a year round water supply which means that the birds are always active all here. If you are there at dawn or dusk then kangaroos can be seen feeding on the grass. It is a great little spot and doesn’t require too much effort to get there.

A funny name for a blog post about Lake Seppings in Albany, Western Australia, but it does describe what happened.

Way back in the Nyittiny (creation times) the spirit Djrat walked on the earth and created south coast of Western Australia and as he walked he left a footprint which filled with water and created a freshwater lake 1.1 Km long and 400m wide. The Minang group of the Nyoongar called this place Tjuirtgellong or “place of the long necked turtle” which was an important food source for them in the summer months. The lake was surrounded by a variety of vegetation. Fringing the lake are bullrushes, sedges, and reeds reeds. Further back were Western Australian peppermint trees, spearwoods, paperbarks, native willows, wattles, banksias and melaleuca. All this provided habitat  for over 100 different bird species including Australian white ibis, yellow-billed spoonbil,  white-faced heron, blue-billed duck, musk duck, black swan, hoary-headed grebe, Australian pelican, Eurasian coot, spotless crake, masked lapwing, dusky moorhen, purple swamphen and buff-banded rail.

All was fine and dandy until 1790 when the British explorer George Vancouver arrived. While he was mapping King George Sound he didn’t see any Minang but saw plenty of evidence that they were around and he later wrote that he found a ‘native village; fresh food remains near a well-constructed hut; a kangaroo that had apparently been killed with a blow to the head; a fish weir across what is now called the Kalgan River; and what appeared to be systematic firing of the land.’ (R. Appleyard. ‘ Vancouver’s Discovery and Exploration of King George’s Sound’ in Early Days, Journal and Proceedings of the Western Australian Historical Society, 1986, pp.86-97). That was the start of colonial settlement. As far as the lake is concerned well initially the settlers tried to do the right thing and in 1887 the Albany Municipal Council applied to the state government for permission to make the Lake and some of its surrounding bushland a botanical park. This lasted up until 1900 when it became a rubbish dump for the city of Albany. This sad state continued until 1972 when it was decided by the department of fisheries and fauna to turn the lake into a water fowl reserve.  Very quickly the community got on board with initially a bird-walk being established by the Apex club of Albany in 1980. By 2004 a walk around the lake had been completed and the lake was given protected status. In 2018 there was a ‘community planting’ of some 22,000 trees and understory plants to provide a ‘biodiversity corridor’ and habitat for endangered wildlife such as the western ring tailed possum.

Every time we go to Albany I always visit Lake Seppings. I love walking around the edge of the lake and observing all the wildlife. I see it in many ways as a beacon of hope. The local community came together and have made a serious and worthwhile attempt to restore the lake to what it once was it still has a long way to go before it reaches its former status but it is a very good start. For the Nyoongar I hope that the recent claim for compensation for the loss of their traditional lands succeeds and can bring them some way of moving forward.
