I recently purchased a K-S1 off adorama and it should be coming in on Monday. In the meantime, went searching for some older lenses for cheap off of craigslist since they might be compatible with the K-S1 and thus I found an ad for a Pentax MX and 3 lenses. The lady I bought them from said they should all be functional and so for $40 I figured why not. The lenses are:
Lens 1: SMC Pentax-M 1.7 f50mm
Lens 2: Bell & Howel 2.8 f28mm
Lens 3: Quantaray 4-5.6 f70-210mm
Google wasn't much help on giving me any information on these so I was wondering if you guys could help! Do I need any adapters for these? Are they decent lenses at least for a beginner? Any tips on using them? What would be a good way to clean them as they have a fair amount of dust on them.
Thank you guys ahead of time
I can take pictures of them if necessary. Sadly not with the K-S1 as it's not in yet
