Is there such a thing as Reciprocity Failure in digital photography like there is in film photography. I know what causes this in film but was wandering if light sensors have trouble absorbing light like the silver in film. I have not experimented yet to check it out. I don't think it exist, but I am not as smart as many on this forum are.
The short answer is no - the physics is different. But digital sensors also have a low light problem called signal to noise ratio. At very low light levels, you will not get a good image even with very long times because of thermal noise. That's why some astronomy applications use super cooled sensors.

I can confirm that the icons are present in version X6. (I don't have X7.) I could not find any setting which removes the icons. At least in X6, the icons appear to be a permanent feature of the Layers palett. When in doubt, rebooting is always the first step.

Just as Consumer Reports recommends you NEVER buy extended warranties on anything, but put that money aside in savings, instead, I consider gray market cameras to be a good buy for the same reasons. Put the difference between gray market and US warranted goods aside in case of emergency.

I agree completely. Buying gray market is not a moral question or legal guestion, it is strictly dollars saved and how much risk you are willing to take. A warranty is just an insurance policy - usually overpriced. When possible, I prefer to be self-insuranced on consumer goods. If occasionally I get a lemon, I'll eat the cost and still come out ahead in the long run.
In 1971, a new college graduate without much money, I wanted to get a good 35mm camera. I bought an SRT-101 from an ad in a photography magazine. I sent a money order to Hong Kong, and three weeks later the mailman delivered my camera and collected $10 in duty. As I remember, the Hong Kong price was less than half of what a US shop charged. I don't know if the term gray markey was used back then. I just considered myself to be an importer. Over the next few years, I bought some lenses and other cameras the same way. Never had a problem. I still have the Minolta gear and it still works.
Last year, I bought a new D7100 from a retail seller on eBay. I paid $1200 for a body and two kit lenses. The exact same items on B&H were $1800. Modern electronic items are very reliable. The chances of a Nikon camera failing in the first year has got be to be much less than 10%. More than that and they would be out of business. $600 savings easily covered my risk. A year later, the D7100 still works fine. If it stopped working (or fell in the lake), I can replace it for about what I saved originally. Adorama has refurb for $700 and eBay new bodies are selling for $600 to $700.
Does anybody know why cameras have this huge difference in price for gray market? I don't see gray market TVs.
