« on: July 23, 2012, 04:32:19 PM »
Get 15% off Canon lenses with code BTENCHG53 at Newegg,
The 15% (Up to $300) is on top of the Canon instant rebate.
This brings the 16-35mmL to $1351, and the 70-200mm f/2.8 II to $1999.99.
Canon seems to be dropping prices due to slow sales even more.  Be aware that Newegg has a replacement only policy, no returns if you get cold feet.

This review is fun to read, and well written.  I enjoyed reading it for what it is.  not a technical review, but some very good sample images.

Interesting.  I know that lots of thin film battery research has been done, but this might even open up the way for things like tattooed on batteries.
 
Then you can easily have a microscopic implanted camera, and have a excuse (charging up) when you sit in the sun.
 
Or maybe just a built-in AF-Assist light ;)

Third Party Manufacturers / 135mm MF Pancake
« on: June 30, 2012, 06:08:53 PM »
Long Long ago, when lenses were simpler, a 125mm medium format pancake was practical, even included a built-in leaf shutter.

Third Party Lenses (Sigma, Tamron, etc.) / Nikon 500mm f/8 Reflex
« on: June 27, 2012, 08:15:07 PM »
I picked up a Nikon 500mm f/8 Mirror lens locally for $80, and finally found time to mount it on my 1D MK IV today.  I am really challenged when it comes to manual focusing, my old eyes are not that sharp.  I had to fool with the exposure, and when I finally got it right, I put the camera into live view so I could use the magnifer to focus, and the exposure was 3 stops off.
For those who don't know, this breed of mirror lens has a fixed f/8 aperture, and are manual focus.  As long as a adapter exists, they work equally well (or equally poorly) on all bodies.

After getting exposure set once again, I was able to get a couple of in-focus shots.  Its pretty frustrating to use.
As expected, its reasonably sharp, and  for a 500mm lens that only cost $80, its a steal. The sharpness is not going to blow you away, the birds were near MFD, so the depth of field is a bit shallow. The awful bokeh was a given, but those out of focus highlights were worse than I expected, when compared to a Sigma 600mm mirror lens that I had a few years back.
Still, for those who can't afford a real 500mm lens, a mirror lens is a cheap alternative.  I should go out and try my 100-400mm l on the same basic shots and crop, but I know it would win.  It cost 20 times as much, so it should be better!
