Ah of course the Minolta lenses come to mind! Those are some of my all time favorites. One of my 'work-horse' lenses is actually a minolta Rokkor-x 135mm f/2.8. I would love to get the 35mm MC, but I can never find any locally and tend to be weary of purchasing used glass online. Do you know of any trusty sellers? Thank you for the suggestions!
Well, since I moved back home (were the nearest photographic shop, digital stuff aside, to be found is at 100Km...) I've bought 99% of my cameras and lenses online.
Yet, during the years, I've had just 2 bad experiences. In one case it was the postal service fault: a Nikon Coolscan 8000 arrived, literally, bent in two (incredibly, even though the seller refused to pay for the damage, I sold it as parts, and I was still able to recover all the money...)! Another time a lens had bad fungus, but in this case I just sent it back to the seller.
My main source is ebay: as long as you read attentively the feedbacks you're not going to have bad experiences, at least not of the kind that cannot be solved by a mail to the seller.
Shops tend to be quite a bit more expensive than a private seller on ebay (or on catawiki, another auction site), but obviously being a shop they have more expenses to front as well.
And it is not always the case: when something becomes "fashionable" you will often be able to buy it way cheaper from a shop. To give you an example, years ago I was able to buy a Contax G 45/2, new old stock, for 200€ while on ebay etc., used, they tended to go for double that amount...same thing happened with my Contax 100-300 and with several other lenses. So don't discount a shop just right away, confront the prices first.
Beside the auction sites another great shop is http://www.secondhan...nl/?page_id=595 (and they have a Minolta 35/1.8 at this page; it is wildly expensive, but it has been on their site for ages, so you could try contacting them and making an offer).
And if you're handy with Italian (or with Google Translate!) you could check as well:
I bought at one time or another from each one of them and they are all good sellers. The only gripe is that, if you ask to pay by credit card, quite often you will be required to pay the commissions (usually around a few % of the sum, if I'm not mistaken around 4%). This doesn't apply to a bank transfer, though.
