an f/2.8 equivalent zoom is the most difficult for APS-C SLR cameras. it's easier for full-frame and more for mirrorless that I expect even higher performance to overwhelm compititioin.

there are...

Zeiss only means third-class Japanese.
though third-class Japanese is still better than first class German.

exactly the same difference between APS-C and 35mm full-frame at a certain f-number.

17-55/2.8G was part of the f-number cheating and it already swindled enough money.

Nikon users should choose 24-70/2.8G on D700/D600, not the infamouse 17-55. 24-70 is still a good choice but now...

a 50-150/1.8 is coming probably.

this is a Canon mount one, so f/1.8 * 1.612 = f/2.9
for others it's f/1.8 * 1.532 = f/2.8
5% error is tolerated so f/2.8 and f/2.9 are the same.

still confused who is who. do you sure the camera tested is really 700D?

though I don't have access to as many copies as lensrentals, my small sample were from different batches, from both factory and NPS, and represent better the over all quality of DX17-55/2.8 which...

I tested four copies of DX17-55/2.8, plus two in the shop and none was good. then I got a chance to check one just returned from NPS and that was not good either.

Tamron 17-50/2.8 was a better...

should make it a standard section (like vignetting and distortion beyond the intended frame) in your check-list that an intern could do it semi-automatically before you return the lens.

stunning at f/5.6 on D200? at a price comparable to 24-70/2.8?

Nikkor 17-55/2.8 is 1.3 stops slower with poor optical quality.

Nikkor 17-55/2.8 is 1.3 stops slower with poor optical quality (doesn't resolve well at open, not so good stopped down).

this lens means nothing for those who have a 24-70/2.8 mounted on 35mm format.

it means a lot for APS-C users for they can not get 35mm format quality (narrower range though) using their current...
