Trees in Black and White.

Playing with the 24mm Sigma super wide II.

That works.

Best regards

I have fond memories of having one of these (the Sigma lens) years ago, super lens.
Both images have that 'pop' when viewed large - look forward to more from your 'playing'

So much better viewed large, nice shots from one of the most under-rated lenses available

Thanks guys for your comments, appreciated.
I have just discovered the following info,

https://forum.mflenses.com/test-24mm-f2-8-fd-ar-md-ais-sigma-yash-zeiss-t85566.h...

I'm quite amazed how it performs against the others in the test. I did pixel peep some shots to compare with a 50mm smc 1.7 and a K 55mm 1.8, ( because that's what kit I had to hand.) The Sigma was just much more sharper even after sharpening and CA correction on the pentax ones, it is a later era though I believe.

I should clarify the ,edges, where the problem unsharpness was apparent.

It is a later era lens but has always had a solid reputation. The lens design may also work better with digital sensors.

Correction to my earlier ramblings, I have another smc-m 50mm f1.7 and it is tack sharp stopped down even in the edges, no sharpening or ca required. Shot same place even with a slower shutter, incredible lens, the other one must need a clean!
