ISO Invariance

So this is new to me and I am not sure I fully understand all the physics behind it. All my previous cameras have not been ISO invariant, that is to say to minimise noise you needed to make sure the image was not underexposed by using an appropriately high ISO. Using a lower ISO and underexposing an image and then pushing the shadows in post would create a noiser image than using a higher ISO and “proper” exposure. Pretty standard stuff and well understood.

Photobombed

I didn’t buy the Sony A7Riv for wildlife but the wildlife at Dove Stone Reservoir didn’t care and this little chap kept photobombing me ! Clearly well used to people he was determined to get in on the show so it would have been rude not to frame up a few shots of him (could be a her of course as no sexual dimorphism in Robins).

Chuffin Cold !

“It’s a warm wind, the west wind, full of birds’ cries” – The West Wind by John Masefield

Well that’s as maybe but I can tell you an east wind in February on top of Standedge is chuffin cold ! – best suited for winter photography said my new book, true, but it didn’t mention the need for crampons !

New Year – New Camera

A couple of years ago I switched from a full-frame Canon camera to micro four thirds largely because I had become tired of humping around heavy kit. Lenses like the Canon 500mm f/4 are frankly hard work and increasingly difficult to travel with. In general I am pleased I made the change and for my long focal length wildlife photography the Olympus m43 cameras with the 300mm f/4 (600mm full-frame equivalent) still make alot of sense.

£6,499 too far

An important aspect of my photographic interest is wildlife, an interest that requires long lenses and good field craft. The field craft I am ok with but my relationship with long lenses is a long story.

Stepping back a few years my go to wildlife kit was the Canon EOS 7d mk ii and the venerable Canon 500mm f4 big white. On the Canon APS C crop body this gave me an effective focal length of 800mm a good focal length for birding and coupled with the Canon 100-400mm zoom on a Canon 5d mk iii a good all around wildlife kit, all be it with one major problem, well actually 2 major problems, size and weight (those 4 items alone weighing in at 6.43kg).

Year-end Walk

So 2020 comes to an end and many will be wishing good ridance to it. Travel restictions have meant that photographic opportunities have been few and far betwen this year and frankly the weather hasn’t helped either. Who knows what 2021 will bring but one thing is for sure, climate change is having a dramatic impact on the weather, it seams that dry crisp winters are a thing of the past to be replaced with seemingly endless drab grey days and rain. A final year-end walk and a final couple of photographs.
