Wonderfully sharp! Lovely image

Agree with others - second one is really good; however no 1 is an interesting little critter - not seen one of them before!

There was a time when we used film and the parameters needed of a lens were well understood. Good lenses could deliver the quality to exploit the finest grain, sharpest emulsions. That was so for decades.
I feel a bit sorry for manufacturers now, because the requirements of advancing sensors need unprecedented quality levels that are constantly being revised upwards. I would suggest this is why the lower cost lenses don't survive as long these days. It's a tribute to the Limited range that even the film lenses are still at the top of the tree.
The new lenses promise to be something special and it will be very interesting to see how they behave on FF, APS-C and even on film for some of us. I think these are exciting times.
Agreed. I had a Sigma 500mm APO lens. With a good tripod etc, I could get fairly sharp images on slide film. IIRC it was ok with the istD 6Mp sensor, but I could not get anything approaching sharp even on the K10D! I got rid of it - wonder how awful it would look with the later sensors!There was a time when we used film and the parameters needed of a lens were well understood.

The confetti one for me too - although I also like no 1 and the b&w no 5

Worthwhile bit of exertion - all are great shots. I took a film of SFX many moons ago, but never got round to getting it developed! The colour ones work best for me as well due to greater depth - but I do rather like no 4.

I have this lens and its a beauty! Got it second hand from someone on here.
A link to a shot in my PF done at f2.8; link and another; link at f5.6 (Can't remember off hand whether these wer on a tripod or hand-held) It is noisy, but generally fast and accurate on AF (although there are occasions when it misses if the target is relatively small and it will go from one focus extreme to the other) and I do miss the 'quick-shift' focus over-ride. Image wise it is sharp, and generally speaking the IBIS works well with it. I wanted it over the Sigma, not just 'cos it's cheaper but it also has a reasonable macro facility (1:3 magnification as opposed to others of 1:5-ish). Another cropped image from my PF - handheld; link
Hope that helps
