Originally posted by pathdoc I think there was a black one floating around as well, albeit not with the AF lens it was designed for, so if you wanted to spend the extra you could do it...
Considering that the ME Super family of bodies are increasingly (and sadly) now becoming less reliable, it is a bit tougher to get a good ME, ME Super, ME F, etc., from places like eBay, primarily due to sometimes inadequate (or even a lack of) testing for functionality.
In the case of the ME F, specifically, to get a fully functional body becomes even more problematic, since, while it is basically more or less an ME Super under the hood, it does have additional mechanical and electronic complexity to enable its primitive AF functionality. And, the problem is not just that more complicated bodies have more things than can go wrong, either (although some aspect of Murphy's Law could very possibly apply here) -- there is at least one additional problem:
In order to to fully test ME F AF functionality, after first installing four button cells in its base, one also needs a functioning AF 35-70/2.8 lens, equipped with its own three AAA cells, but many ME F owners and/or sellers don't have one of these lenses. Not only were the lenses sold separately (and I'm not sure if there ever was an actual ME F "kit" or not), but there eventually was a period of time when Pentax and/or the photo stores started pushing the ME F just for its ability to focus confirm with all lenses (and Pentax even had a full-page mag ad emphasizing this), possibly to try to clean out stocks of ME F bodies when it had become clear that the ME F was not going to be a huge commercial success. (There actually was a period of time when one could purchase an ME F body for almost the same price as an ME Super.)
The bottom line from the above is that there are many more ME F bodies out there than AF 35-70/2.8 lenses, and this increases the chances of ME F bodies being offered for sale without thorough or even minimal testing. While one might expect a seller to at least throw a couple of button cells in an ME Super to give it a quick test, one cannot expect someone who is selling an ME F without the dedicated lens to go with it to be able to honestly verify full AF functionality. (Furthermore, some additional familiarity with the unique features of the ME F and its matching lens on the part of the seller would also be required for the testing as well.)
[The corollary of the above is also true, of course -- someone selling an AF 35-70/2.8 lens cannot fully test it for use as anything other than a rather bulky MF lens without using a functioning ME F body for the testing.] [And BTW, the AF 35-70/2.8 ~IS~ a good lens optically, and it's too bad that Pentax never came out with a more compact MF version of it -- but I digress...]
So, probably the best bet is to buy an ME F ~with~ the AF 35-70/2.8, with both having been successfully tested together. Even if you ultimately wanted to play around with the ME F mostly for use with a few of your other lenses (including using your F and FA lenses as MF lenses only) employing focus confirmation, buying an ME F, tested along with its matching dedicated lens, would increase your chances of not buying a "dud".
