I use a Nikon 70-200 F2.8 VR1 at 200mm with a 10X objective on a full frame D800. I get a small amount of vignetting, but this is on an FX sensor. I would expect little to none on a DX sensor.

In addition to the great imaging, extremely interesting subject matter.
Thanks g4. Nice to look at but a real bear to design!! This is what I do for a living, chip design, so the aesthetic value is icing on the cake!

Rik,

Here's an image stacked with Scales turned off. Seems like a little better hold on the perspective to me.

Rik, Chris, Mark, Thanks for the notes. This as the earlier image were shot a few months ago, so this wasn't a new attempt. Thought maybe the perspective was better. I'll try with the Scale off when I get some "free" time, also try PS. Just got home from a 3 week bus/vac trip and the pool pump is b...

Here's another chip image (same FGU chip) with maybe a somewhat better perspective. This is sitting on a dime. All these images are downsized from the original TIFF files.

Rik,

Thanks, you give me some things to think about. Just got back from Burbank on a business/vacation trip, so I'll need a couple days to digest this.

Cheers,

Excellent, excellent! The lighting is spot on. I'm not sure I've ever seen a chip in quite this pristine condition. You guys make these things, then? --Rik Rik, We design and layout these chips and have them fabricated by a silicon "foundry", IBM in this case. The design is quite involved and the l...

Chris, Rik, Yes the perspective of the chip is warped. I did not try and correct this in PS, believe this is due to the different distance between the effective lens and subject as you move the lens to image across the chip. The chip distance is much larger than the DOF which I believe changes the p...

Another Chip Image

Bare chip image of a banged up chip (defective) from our lab. This is a Frequency Generation Unit, thus FGU nomenclature. All these chip images are very low resolution. The balls are solder that is used to mount the chip upside down, called flip-chip. http://i1330.photobucket.com/albums/w564/mawyatt...
