On Fujifilm makes XF 90mm F2 R LM WR official article (136 comments in total)

It amazes me just how many posters like some of those below, classic case being historianx, prove the old adage that it is better to remain silent and be thought a fool, than to speak and remove any possible doubt.

If he had bothered to check the specifications he would find that Fuji supply a lens hood, not only with the new 90 mm, but with every other lens they produce.

Mebyon K: There are three things I can see no mention of; the point at which diffraction starts to occur, the very high lens quality necessary to prevent optical defects becoming apparent and the almost flawless hand holding technique required with a 28Mp crop sensor. This equates to approximately 60Mp on a full frame sensor and at that pixel pitch all three will start to become problematic.

In Photozones' review of the Fuji 56mm f1.2, the next Fuji lens I am intending to buy, it states that diffraction effects start to become visible at f8 and any aperture smaller than f11 should be avoided. Given that the Samsung has approximately twice the pixel density of the Fuji, 28 against 16, then the figures would become f5.6 and f8.

Also in the Nikon interview at CP+ that I read today, one of those interviewed highlighted the problem of loss of quality due to hand movement with the high pixel density sensors now being produced. I just hope that the camera makers in their quest to grab headlines with increased Mp don't forget those of us who actually go out and take pictures under real world conditions.

gl2k: About half the weight. WOW. love it.
If AF performance matches that of its f2.8 sister I'll buy it.
Focus breathing ... ?

On the subject of focal lengths, I hope the Nikon f4 zoom is closer to the claimed focal length of 70-200 than the Canon f4, which is only 74-188 and should more correctly described as 75-190 at best.
