Hi Jim,

Sorry, I was unaware of that one as I had not come across any reviews.

Manual focussing ha, ha. Now you know why I have the D2X.

Your dad was checking out my A/F 85 f1.8 today :D :D I think he was impressed.

Don

Thanks Lee : )

Hi Don... mmmmmmm D2X... yummy! Oh, yeah... Dad was impressed with the lens for sure... me too when I saw the images... so sharp!... the shopping list grows ever larger hehe! ; )

Jim,

You're asking for something that is approaching nivarna. I think Lee's getting closest to the mark here. Practice your hand-holding technique. I know Lee is ex-army, and was probably a world class sniper judging by his photographic abilities. Lots of practice - in your own home taking pictures of cornflakes packets if that's what it takes - and refining your technique will help tremendously, regardless of the glass you're using. Breathing is key in my experience, hold your breath just before you press the button.

Jim,

Links to two reviews of the Sigma 20mm f1.8 that I have managed to find.

From those it appears wide open is soft and you may be at f4 for acceptable centre sharpness. For your off centre subjects then you may even have to stop down to f5.6.
I think you are in a try before you buy situation with this one.

Don

Thanks for the info Don : )

Hi.
Very low light documentary with full frame 35mm/FX sensor....24mm f/1.8 and 35mm f/1.4 I would have thought??
Just thinking that anything wider than 24mm takes on particular influencing effects, which could give your shots a very 'same' look, which might not neccessarily contribute to all your shots....
just my thoughts
