Elyas, I'm no expert on these particular lenses, but since nobody's replied so far, I'll throw my 2c in.

These appear to be basic, common prime lenses, and in general, they're not all that valuable because the f-stop rating isn't spectacular. f1.3 is respectable, don't get me wrong. But where the value goes up is with the better lenses with f1.2, f1.1, and the unusual f1.0 efficiency. Of course, better lenses are also optically sharper, and I don't know how these would be.

I've tried to sell lenses on eBay before and found it tough to do better than $10, and even then didn't sell everything.

The lenses mentioned are the type as supplied new with a projector. Therefore their resale value is possibly nil.

Most projector owners would be looking for lenses of differing focal lengths, or with larger apertures.

Thanks guys,
well, I guess yours truly just lost some money. Not on all three, thankfully, as the B&H, I got for free, the Isco, I bought for USD 35 and the Astro came with a Siemens 2000 I bought for USD 5. Thanks again for your input and have yourselves a great weekend, gentlemen !!!

Best,
ET
