Question about Nikon Process 210mm f/9 Apo-Nikkor Barrel Lens

Open Question

Usefulness in UV photography

I've seen this lens describes as "an excellent performer for UV, with no focus shift" but I've also been told that "Apo Nikkors do max. 380nm (which is just 20nm into UV), so cannot be called useful for UV." I'm guessing that there is some fall off in UV transmission below 380nm, but still enough to make it useful for art UV photography using longer exposure times. Anyone care to comment?

SOURCE: consistent under exposure

Under exposed should be minus not plus number.
Lucky you didn't buy Canon 5D or 1D- they have focus and exposure problems.

Hope you are not using the pop flash that is on the camera. If you are, then turn off the Red Eyes Modes.
Set camera to manual mode and lower the F number(open up to half or one stop).

What studio lights are you using? Increased the light output of studio by those number and shoot like you normally do.

The distance focus ring, is it supposed to turn all the way to the macro symbol when you are focusing on a subject that is very close?

If you're right "on top" of the subject - then, yes - it should indicate "macro". Macro focusing is for "very up close" photography and is exactly as you describe. You simply physically move the camera a little closer to or further from the subject to focus.

Not all lenses are capable of macro focusing. The vast majority of these non-macro lenses are required to be at least a couple (or more) feet away to focus. Macro lenses on the other hand can usually get just inches away - which is a great capability.

Enjoy your macro lens!

My Sigma apo 70-200mm f/2.8 hsm lens functions fine. Focus works and zooms just fine. The problem is the front part of the lens is loose. You have to hold it to secure it while shooting. Otherwise you can...

Am having the same problem. I fixed it once but can't remember how I did it. I think there are screws under the mounting ring -which has four screws itself. Then, I think under the green computer board, there are other screws that should be tightened... I will look at mine tomorrow and come back here to report.

Trouble focusing with sigma 70-300 DL macro super lens

It will not focus on anything closer than 5 feet.

(From Sigma lens literature)
Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.

I need to know the value and info on this lense

There are two versions of this lens.  The Telemacro version takes 77mm filters and is quite good.  It sells for $325-400 depending upon condition.  The other version "APO" is not very sharp and has low contrast.  It takes a 72mm filter and usually sells for approx. $125-$200.  I would not recommend this one for any serious photographer.  The Telemacro version is a nice affordable 400mm lens with decent performance.  Both lenses have slow AF, but the fast focusing alternatives are hundreds to thousands more.
