Will there ever be a Canon 5D or Nikon D800 appreciation thread?
I see nothing to appreciate in these DSLRs, and I douct that in 37 years they will still be in condition to take pics.

Hello folks,
I'm thinking of getting an F (Photomic FTN) or an F2 (AS). Any tips on differences between the models?
The FTN meter has a couple of key flaws.
One is the carbon ring resistor which can wear out.
The second is foam which was placed around the prism, to isolate it from the housing. With time this foam deteriorates and eats away the silvering on the prism. This desilvering becomes visible as irregularities on either side of the eyepiece, or as a line down the middle.
Robert Decker lives in Utah, and he has replacement ring resistors as well as replacement prisms. He can also adjust the battery voltage to 3V, so you can use alkaline or silver oxide cells. He will remove the foam on the prisms so that they will not desilver in the future.
I just sent him a couple of FTN prisms.
General overhaul is $85, and add $35 if you need a new prism.
Turnaround time is 1 week.
I finally bought a "like new" prism from Japan just because it didn't have desilvering. Then, a good soul from photo.net sent me his Excellent + condition FTN prism that suffered from desilvering.
Both now work like champs!
For the F2 prisms, the F2A (DP-11) has wirewound resistors (like a rheostat), that Sover Wong tells me will last a lifetime and then some. The others will eventually give out - even the resistor in the AS prism (DP-12). However, he has custom made ceramic resistor replacements for the AS prism that have been proven to last over 1 million revolutions without any decay. The cost of the ceramic resistor is $40 on top of your service fee. He also has new CdS cells (again custom made), which he can replace any dying cells in your original meter.
