New Bird Lens
Jun 28, 2020 09:46:01 #
This is for Sony enthusiast and probably of little interest to most people.
I was looking at DXO to see which of my lenses was sharpest...it turned out to be the Sony 90mm 2.8 macro which scored 61Mpix on the A7R4. I've had it for a while and use it for macro.
So I took a few snaps with it at a distance of about 10'-12' and processed an image as I normally do, except crop which was much deeper.. The result blew me away. As one can see the image size is a small fraction of the original.
I have been contemplation a faster bird lens for low light conditions. The 100-400 GM does not cut it early morning or late evening at my location. It looks as if I have it.
Take a look, its not a great image but it does make a point.

Looks like you may have a point there. Very nice image. Good glass is good.

This would be a good lens/camera combo to use the 1.1-2X Clear Image Zoom or any other pixel enlargement software you choose !

You may be right Larry, but I am hooked on raw and have all the size I need.

I think you can figure from the pixel dims shown ....look up the original pixel dims for the A7RIV

Multiply the linear pixels and divide by the original product of the linear pixels.

Good for you, I have been using a Tamron 180 macro, usually with a 1.4x extender for humming birds for a few years - on my 7DII it has the angle of view of 403 mm which is deffinitely in the birding lens range.

If I read the dimensions correctly, that is a huge crop and the detail remains pretty astounding. Looks like you have a pretty good alternative in that lens as long as the as your subjects are fairly close in. Although I have not done much in the way of research, your alternatives are quite expensive (but in my opinion worth it).
