What mount is that on the Sigma?

So I was wandering past a Cash Converters, like one of your Pawn Shops, and because I'm retired with nothing better to do I wandered in.

They have a camera cabinet and in it are about 6 to 8 Sigma lenses for not much money.

However, whoever took them into stock didn't pay attention to what these things are for and has not noted what camera they fit on.

Is there any quick way to determine this? I'm looking to put some "you'll never sell that" pressure on them and probably could do so if I knew what I was looking at, and they didn't know I knew.

Really hard to describe lens mounts without picts ....

If they do not know what they fit, they probably never tested them before they took them .....!?

I only own one Sigma lens. The rear lens cap says Sigma for Nikon.

Could be Nikon, Canon, Pentax, Sony A, or Sigma. All are pretty distinctive and with a little knowledge you can tell by looking at the mount itself. No markings on the lens will tell you what they are for.
As already mentioned, markings on the rear lens cap could provide a good clue. Note that Pentax and Sigma mounts use the same cap.

Yes, there is that to remember.

Invest the time to memorize the most common lens mounts. Better yet, memorize as many lens mounts as you can, as a few of the obscure mounts can be mistaken for the common ones. Once memorized, from that point on you will be able to quickly determine what mount you are looking at in most situations.

Here is a link to a visual guide to lens mounts, I think there are others out there but it is becoming so hard to find things on the internet other than marketing.

Thanks, I figured when they saw part one they would search for part 2.

That's probably more than necessary.

If the OP is considering purchasing the lenses for his own use, he only needs to learn what *his* platform mount looks like. If it looks different, he shouldn't buy. Pretty simple.

If they have your brand of camera or lens in the store use one of them to check it out. You could also carry your camera with you to check out the lens. Having a photo of your lens mount with you or on your cell phone would help too.

If you own a lens then just take that lens into the Pawn shop and you can check it against all the mounts on the lenses they have. Match your lens mount up with their lenses and try the one on that matches your mount. Easy Peasy.

Won't work. Behind their poker
face they're just thinking "Jerk".

You already said the prices are
low. OTOH, if lenses are priced
individually, it is reasonable to
ask about a "group discount" if
you want more than one.

I think the OP was hoping for the lenses to have a non popular lens mount so that the could tell the seller that he would never be able to sell them and get them for cheap.
