Well, there are a few, like: 10.5mm fish 35mm f/1.8 40mm f/2.8 Micro 85mm f/3.5 Micro ...but I don't expect to see many wide fast primes any time soon.

I wouldn't worry about it. Best bet is to use high quality filters like B&W, which are made with brass rings. The brass threads when threaded into aluminum mating threads on the lens are less ...

Here is the best demonstration I've seen of the depth of field thing I was talking about: http://toothwalker.org/optics/dof.html Check out the pictures of Gromit. (Upon re-reading this link, I ...

Yes, it is a lens that demands the best technique. The physics of long focal length macro are just not in your favor. I ALWAYS use a tripod for macro, and not just any tripod will do. The stoutest ...

I agree with the comments and recommendations from Michael. I would like to add a comment, which is that the working distance thing is somewhat overblown, IMHO, unless you are specializing in ...

Really? You find the upper image to be sharper? That's not how I see it. View in the gallery, and flip between the two images. Look at the '0' on the far left, or the 'L' in Longines. Also the ...

Well, the Sport Optics division of Nikon is a completely different thing than their DSLR operation. I assume you've tried contacting support, over on the Sport Optics website? http://www.nikonsport ...

Product Management is one of those things that looks easy from the outside, but is very different when your job is on the line. Several replies have laid out plausible reasons why. No one 'knows' ...

The lens is variable aperture. The green dot is for aperture when set to 28mm, the yellow when set to 105mm. This only really matters if you're operating the lens in manual mode, or using an ...

The best term to search for is "Bellows Extension Factor" You'll find pages of info, tables showing factors for various combinations of focal length and extension, etc. It's a feature, not a bug.

Assuming you are talking B&W, then sure, you can start developing your own film. This is another craft that can end up consuming a bunch of time and resources. It's like asking, "Should I brew my ...

Stay away. I have two in my closet that are bricks because the shutter position sensors have failed. Not worth fixing.

Oops-- re-reading the OP, I see that you did factory reset. Sorry, missed that. Also OP says same thing with 4 different lenses.

Certainly looks like exposure compensation is jacked up several stops. (Note that B4 is different from the +/- button setting. Can you verify that there is no "+3.0" or whatever in the viewfinder ...

While the Nikkor 300mm PF is excellent, by the time you add a 1.4 TC and crop it to an equivalent 600mm, I doubt it would be better than your Tammy, although I have not used that lens, so can't ...

Yeah, who are you going to believe? Me, or your own lyin' eyes? Two things have changed, to make modern optics better: 1) Technology: Computerized optics design tools are vastly more sophisticated ...

Not sure what this means. Yes, the lens is wide open when AF is happening, but the AF hardware is operating at an effective aperture of f/5.6 or so. The precision of AF is not really dependent on ...

Ahh-- yep, that would do it. Never seen one like that in the wild. OP: If you find a solution, let us know.

Quoting the Nikon USA website: Compatible models with limited functions: D5, D810 series, Df, D750, D7200, D7100, D5200, Nikon 1 series with the FT1 ...so, looks like it will work. Limited ...

Your question contains the answer. The reason that you don't see screw-on hoods that are tulip shaped or rectangular is that the angle of the hood once it's screwed in place cannot be controlled ...
