Usually new generations do perform better. What is amazing is that even the first generation is awesome.

When buying my first PC in early eighties I could choose either a 10 MB or 20MB HDD, I went all the way and got the 20 MB version and Hercules graphics card & 13" amber monitor!

Lousy DOF?, it has more DOF than any "full frame" or even midsize camera...

New Sigma 35mm f/1.4 in Nikon mount is less than $1000 I believe... And it is one of the sharpest lens ever available for FF cameras.

You can not really get much shallow DOF effects with wide-angles, except at very close focus. I do not think that would be the main reason for most people to by this lens. More lens speed is often...

The mechanical manual focus coupling certainly makes MF more precise and gives a solid feel, but my experiences with the same system in 14mm lens was not 100% joy only: the focus ring has often...

If this 23mm is like the 14mm and 35mm, you are going to be pleasantly surprised: 18mm is merely good compared to those excellent lenses.

View angle would be a perfect measure of that. 60 degree lens would be the same on a smartphone, APS-C, 135, 6x7, 4x5, whatever.

At least in fixed lens cameras the lens should be described with picture angles like 80-4 diagonal degrees for a 20x zoom. Then the buyer would know exactly what the zoom range is no matter what...

Two polarizers: how much light loss there is?

Sounds like a good idea which is really not needed. And even less in the future with ever sharper sensors.

Those 5 pictures do not show if a foot touched the top of the curved wall lining the ring, as the series do not go far enough in time. That would be a foul, and only video (or sharp eyes) could...

Funny guy...

When I tested my new Fujinon 35mm/1.4 against a Canon 50mm 1.4 I had to recheck several times from the EXIF that I was really looking at frames shot wide open with the Fuji. They were...

Autofocus lens would have to have light, easily movable and relatively few individual lens groups. When doing a no-compromize optical design the lens movement becomes complicated and heavy, too...

If this zoom can hold f/4 to 400mm, why not a longer zoom with same lens diameter?

Re: Marvol: "on a 36MP Nikon you wouldn't even need the TC, you can just crop back to 24MP".

1.4x linear crop would drop the pixel count to half = 18 MP. Which still is the same as EOS-1DX and...

With 8x10 plates is was possible to use f/64 without much diffraction, now with modern small sensors diffraction sets in around f/11 with MF backs, f/8 with best FF DSLRs and f/5.6 with APS-C. So...
