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.

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).

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.
