Bigger sensors contain more megapixels, but sometimes the true physical distance from pixel to pixel is smaller. Things like noise depend on true physical distance, so it is an interesting ...

Not my taste, except for the crocodile.

I back that. Macro asks for speciliased technical tests, resolution at 1:2, 1:1, 2:1, something like that. And aperture with highest resolution.

At my 21st birthday I've got an enormous present: 1000 dutch guilders. Ten times more than expected as nonsmoking bonus. I immediately knew I would buy a camera, but it was not enough money to buy...

What they didn't like: 'Size and weight make for awkward handling.'
That's how gravity works, it's better to like gravity, you can't avoid it.

I very much like all efforts to come closer to...

When you do love optics and making things I can imagine that you love making things like this, not having the option to become a serious big lens selling firm. Although I personally would rather...

Very interesting. I remember when that Nikon 220 degrees came out. Wasn't there a Swiss lens showing much more degrees? I don't remember details.
As we ourselves have an over 180 degree view...

I don't mind watching the original movie.

Why say things like "Size and weight make for awkward handling on EOS R/RP"? It's like complaining that 1 liter of water weighs 1 kilogram.

Back in 1964 my father bought an s1a, and I was allowed to use it sometimes. I was 14 at the time. This Pentax is by far the most important. For me ;-)

I think the stars are a lens fault. And f/22? Much diffraction unsharpness...

Maybe redundant, on the other hand shooting wide screen is more critical, I think.

How do these lenses really have the special cine properties? I saw a movie I made 30 years ago which did not have them at all!

On this page https://www.dpreview.com/buying-guides#usecaseSectionTitle macro photography is missing. But maybe that's logically because there are macro lenses but no macro camera's. One feature ...

A good landscape is in the eye of the photographer. High or low dynamic range, ultra wide angle to tele, nothing prevents you to make a very nice landscape pic.

The Schmidt corrector in Thüringen is just 1.34 m wide. So the lens of this article is indeed the record holder. The lens is 155 cm wide and 7 cm thick. The total optical system is a beast of...

I don't know. The biggest refractor (telescope without mirrors) is of 1897, diameter 1.02 m, Yerkes. Catadioptric systems contain one or more mirrors with a lens to correct aberrations. Schmidt...

This is very very interesting. When I studied astronomy for one year fifty years ago, especially optics and mechanics of big instruments had my interest. I followed the field a bit through the...

I would have liked a more systematic sample gallery, with 1:1 and 2:1 to compare them. And with a clear choice for certain stops. The raspberry for example is shot at f/22 and the picture has that...
