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

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!

Sports / The Destroyer
« on: May 21, 2012, 01:16:04 PM »
We have a friend who has recently acquired a Monster Truck named "The Destroyer".  He was in town for a display event, so I snapped several images Saturday with my new D800 and 24-70mm lens.  I wanted to check out the DR, one image has the sun reflecting off the truck, it was totally a bright spot to my eyes, but there is actually some detail in the image.  Roger climbed into the truck and snapped some images as well, they also handeled the bright sunny day out with the dark interior quite well. The Images are unedited.
 
I've been trying it and my new Canon 1D MK IV to see which I like best.  I really did not want to like the D800, but so far it performs well, and the detail and DR in good light is amazing, in low light, it is just OK, but good up to ISO 6400 with a reasonable amount of NR.
