Suspicious lens-fu.

There's a photograph of a Persian gold finial resting on a highly patterned cloth on p. 56 of the August 2008 National Geographic (directions to find it online inside). The finial is in tack-sharp focus with significant depth of field while the entire cloth is pleasantly blurred. Shenanigans? I would love to know how this photo was taken. [more inside]

Telephoto lens for Nikon P5100

I'd like to buy a telephoto lens for my Nikon P5100 . There's a bunch on ebay & Amazon - Tokina, Opteka, Fotodiox - for between 40 & 100 bucks. Are any of these lenses/ brands worth their dollar? ($100 is my max, so the $250 Nikon branded lens is not in the running.)

Old Nikon Lenses

Photo of the Rising Sun.

What caused the light to do the weird radial effect in my picture? I'm guessing it's the UV HAZE filter I leave over my lens? Does the effect have a name? Like some weird form of "blooming"? Shot with a Canon Rebel XTi with a 28-135mm USM IS, 6 second exposure.

Best walkaround zoom for Pentax K100D

I bought the Pentax K100D dSLR, partly on recommendations from here, and I love it. I have the 18-55 kit lens and the 50-200 zoom lens, which I mostly use. Now I would like to buy a faster in-between zoom, somewhere from 24-28 at the low end to 75-135 at the high end. I am trying to figure out whether to buy a Pentax, Tamron, or Sigma lens and am getting confused with all the contradictory reviews. The Tamron 24-135 is praised to the skies by some and trashed by others. I am leaning towards the Tamron 28-75 but would like something closer to 100 mm. Any advice?

Favorite Nikon Macro Lens?

What's your favorite Nikon-compatible macro lens? I'm completely new to macro photography (and still pretty new to photography in general, having purchased my first DSLR a little over a year ago), and I'm leaning towards the Nikon 60mm f/2.8D AF, largely because of the price differential between this and some of the other Nikkor macros. Anyone have any great experience with some of the makeshift macro lenses (using extension tubes, reversing rings, etc)?

What kind of tripod mount ring do I need for a Canon EF 100-400mm f4.5-5.6L IS USM Telephoto Zoom Lens

What kind of tripod mount ring do I need for a Canon EF 100-400mm f4.5-5.6L IS USM Telephoto Zoom Lens? I bought a used lens, but it's missing the tripod collar mount ring. It looks like Canon makes a few different mount rings, and I can't figure out which one I need for this particular lens. Does anybody know? Even better, if you know where I can get one on the cheap. If there's an off-brand solution out there, I don't care who makes it as long as it fits my lens and works well.

tap that glass

I'm interested in fitting odd lenses -- and making custom lenses -- to/for digital cameras and digital video cameras. I'm not terribly concerned with the electronic side of things, so you shouldn't be either. What I'm looking for is a crass/crash course in optics -- something (a book, a video, a class, a kit) that will teach me the basics of optics and allow me to force photocopier lenses, telescopes, and microscopes onto unsuspecting recording devices.

Weird optics

Let's say I find a shiny spherical object and under point lighting, I move it very close to my eye. I then focus on the bright spot, but focus at a distance of 1-2 feet until the patterns are in focus. At this point, it looks like a bad microscope. Am I looking at part of my own eye? Is this a documented phenomenon I could read about?

Help me with my White Balance problem.

I've been having a bit of problem getting my WB set just right on my new 30D. I think the canon's have a tendency to AUTOWB a bit too cool for my taste. I'm thinking about getting an Expodisc or something like it. Do they really work as well as the advertising says in setting your custom White Balance? Could I achieve the same effect by putting tissue paper or tracing paper on the lens while setting Custom WB? Help!
