Canon LTM Canon 7,7s,7sz price

Canon M39 M39 screw mount bodies/lenses
The price on these cameras varies a lot depending on condition chrome or black and which model all come into play and then if there s a lens involved that can make anywhere from $50.00 to $1000.00 differance in the price.

The 7sZ is the most expensive and the hardest to find then the 7s both of these have Cds meters making them more desirable.

The last Black body only to sell on ebay went for $1575.00 in the the last week a chrome model 7 with 50mm f1.8 sold for around $300.00

Kevin cameras has a very nice 7 w/ 50mm f1.8 for $675.00 That's the only one I know of on line for sale.
 
I paid $264 (incl S&H) for a 7 body last Fall. 100% functional but had a few light marks on it. Got in an e-Bay BIN.

my 7 was ~450 USD last summer. Exc+, quite no shutter curtain crinkles, working Selen meter and a nice 2/35: Small fungus, removed in between, Exc+ glass, barrel showing marks. Assuming the 2/35 is 250 USD, the 7 body was 200. There are 7 under 200 at ebay, but usually in ugly condition and meter dead.
7s and 7Sz are much higher for collecting reasons. Don't understand it as a user. you can trust a good selen cell in daylight and it don't need 1.35V (mercury) batteries.

cheers, Frank

User advantages of 7s over 7:

-- It has an accessory shoe -- big plus if you plan to use any lenses wider than 35mm. The 7 has no place to put an auxiliary viewfinder unless you can track down its very difficult to find add-on "Accessory Coupler."

-- A properly-working selenium cell is fine in daylight, but a CdS cell is more responsive under dimmer light conditions. The mercury-battery issue is a problem, all right, but there are various solutions including Wein Cells, the MR-9 adapter, and having the meter circuit adapted for 1.55v silver oxide batteries via addition of a Schottky barrier diode.

Those advantages plus the fact that far fewer units of the 7s were produced than the 7 help account for the higher price, in addition to the collector factor.
 
hi jlw,
"having the meter circuit adapted for 1.55v silver oxide batteries via addition of a Schottky barrier diode."
who can do that and what does it cost?? Does it compensate the fact that the 1.55V batteries lose voltage continuosly and this effects measurements? I can tell you from my Spotmatics: I hate that mercury-battery-stuff and don't want anythin more that use it... f**/)§$ Wein-cells.. costs a lot and be empty within a year after no usage, and not as precise...
I can trust my Selen Cell until sunset. When it says "quite no light anyway" ...well then I open the f-Stop 1-2 stepss more and it's OK with modern color neg. film... you can trust your CDS-cell more? At moonshine or with silides film? I would wonder....

With the adapter shoe... well it has none, indeed. The 7 is my "street camera" - for ultra-WA and their finders I've got two Bessas... Just for collecting reasons I got the "Accessory coupler" here in German ebay for 26 USD (probably nobody has a clue here what's this ugly piece of steel is all about, found some auctions in the US finsihing for same price as some cameras it belongs to... ;-)

cheers :)

You can do it yourself if your solder-fu is strong. It's just one component that needs to be spliced into the wire from the battery compartment to the meter circuitry. If you do it neatly, it can be reversed later if you change your mind. I haven't tried it on my 7s yet, but have done it on some other devices. The diode (1N314, I think) costs a couple of dollars.

The output from 1.55v silver oxide batteries stays quite linear, much like a mercury cell's. There's an initial dropoff of a few mv within the first few minutes of operation, but after that it stays stable for a long time. It's the alkaline 1.55v cells for which you have to watch out -- those do have a declining voltage.

If you can find some more at that price, it could be a business opportunity!

Hi-- I think your competent local camera repair guy can do this for most cameras, while some apparently don't have room for the diode.

And your frustration with the Spotmatics was wasted; they already have the bridge circuit as part of the original design. So they can use alkaline or silver cells without affecting meter accuracy.
