2.0? For macro absolutely unnecessary.

I read is as f=7mm and f/5.5.

It maybe depends on the number of pictures you have? I always start with trowing away most pics. In macro, my main subject, much is just not good enough. Every day is stored together in good old...

A Owens, Of course.

The best camera for wildlife? I should always start with the glass for wildlife and after that comes the choice for a camera. Glass for wild life isn't cheap.

With money I would hire a team of specialists that invent exactly the macro equipment I am missing. I know how it looks, but the money is lacking.

6 elements in 5 groups they say, but on a diagramm it is 6 in 4. FD lens of march 1971. I bought it in march or april!

It reminds me a bit of my 135 f/2.5 of 1971, at that time a comparable 'beast'. Diameter 67 mm, length 110mm (room for a mirror of course). I cannot find the number of elements.

I remember that one coming. Number of elements: 3... Different era.

Nice ideas, but workable? A TC at the end means glass elements of small diameter, somewhere in between would ask for a flippable big element.

Olympus still exists, but has no camera brach anymore, that's all. https://www.olympus-lifescience.com/en/

Are they better than old mirror lenses like my Sigma 600 from the early eighties? Mirror lenses have just one advantage: size and weight, and in some cases that's a big advantage.

The differences are huge, but for pictures seen on a screen for just one second this maybe can be neglected. But there is one enormous difference: the glass. For me it all starts with the search...

I only was talking about the image sensors.

At least the lens is the biggest ever.

Technically quite a thing, projects like this. Maybe they could do most of the work and in the last year only add the chips, with the latest chip technology. That technology is developping rapidly,...

Perspective is wrong... Artificial intelligence or artificial dumbness?

Pixel size is given: 3.76 micron. That's in the same range as most camera's, Olympus OM-1 a bit smaller, 3.35 micron I think, Canon R7 (and M6) 3.19 micron, Panasonic GH6 3.00 micron. (Calculated,...

@toomix When they only use focal length they more or less are wrong... Magnification is the deciding thing, You can do the math yourself, you need object distance, image distance, circle of...

DOF in macro depends on magnification factor, not on focal length.
