Yeah, the professional's favourites, Fuji, Pentax, and Sigma...

Excel can do nice things... I designed our utility room and kitchen floor tiling layout with the random number generator, two shades of brown tiles, the floor getting lighter from 95% dark to 80%...

@ breschdlingsgsaelz and SteB: This zoom does have f/4 at 400mm, so why would a 180-560 f/4-5.6 not also have f/4 at 400mm? So why would you loose a stop at 400mm? Now it is certainly lost when...

I have to ask the same question I did when the Canon 200-400 version came out: why not just make a 180-560mm f/4-5.6 Zoom? Is it because variable maximum aperture lens does not sound professional...

Modern, complicated lenses with a dozen well coated elements or more can have transmittance values somewhere around 97% or so. Even then the digital camera contrast bottleneck at the moment is not...

Most likely the lost light is just spread round and makes the contrast lousy. That will be a huge problem when trying to make this invention to work in real life.

Very true. Contrast, I bet, is a big problem with these. Even the glued-together fresnel type elements used in some Canon and Nikkor compact telephotos tend to spread the light more than...

Yes, of course I was using full matte screen on my F1... Easy.

I had a Canon 135 f/2 lens in the early eighties, and of course it was manual focus only. Mostly used to shoot ice hockey... Had to nail the focus every time, but at that time we actually still...

Nikkor 135mm f/2 DC is autofocus (with Nikon pro bodies with focus motor)... And the fore/aft bokeh can be controlled with the DC ring. It seems this lens seems to be mostly forgotten, even though...

With modern huge capacity cards (maybe 2 of them...), this gadget would be needed, like, once in every two weeks...

I just spent a month in Nepal, and did not change the card once. Over 3000...

Only if you are able to crank 25/30 shots per second. Better start practicing your thumb for those longer takes...

During the last 5 years of professional photojournalism (now retired) I started using mirrorless cameras more and more (Fujifilm X-Pro1 to X-T2) because they were so much lighter, quieter and...

@durask: Mark III does not have a delay, you can shoot several pictures per second just by pressing the shutter repeatedly. Just turn the preview off.

Or simply choose continuous shooting from the...

If you have the itch, consider this: you get a fast camera with narrow angle telephoto with large aperture for about $2000. How much does a 200-400 f/4 or a 600mm f/4 alone cost? If you are a...

The lens is TOTALLY different, and MUCH better. So they are not "fairly similar" in real life, and the optical quality of the new lens is the main defining feature of this camera, and version III.

The lens in III and IV versions is optically considerably better than in the previous versions. That is the main strength of mark III and IV, so forget the first two iterations of this camera.

@Ebrahim Saadawi:

For once a sensible and informed answer to the "equivalency" madness. Thank You!

I have the previous model, an amazing camera already.
