Hello! This is my first post so I thought I would share what is in my KP bag. But first I will explain how I got here. A few years my Nikon D600 and bag was stolen, I was using it to photograph some industrial equipment for modification. I needed a cheap capable camera because I was not about to take anything expensive there again. So I got a used K5, I already had some old Pentax manual lenses from a K01 I owned for about 1 week, and I bought a used 18-55 kit lens to go with it. My total all in price was less than $400. I found the K5 much nicer than expected (based on my K01 experience), more than adequate for the job. I eventually did replace the D600 with a D750 because I still had some nice Nikon lenses. I kept the K5 for its size and convenience, and eventually talked myself into a KP. So now I have all three.
Here is my KP bag. Pentax KP, Pentax-DA 18-85 1:3.5-5.6 ED DC WR zoom, Tamron 90mm F/2.8 macro, SMC Pentax-M 50mm F/1.7, and Sigma 100-300 1:4.5-6.7 DL zoom. Accessories include small carabiners to hold the strap on for easy removal, two batteries, large hard case for storing tiny SD memory cards, JJC-TM-PK1 remote and intervalometer, and HQRP AC Adapter. For several months after buying the KP I collected several more lenses at thrift stores, obscure on line auctions, and yard sales. These include the radioactive Takumar 50mm 1.4, M42 adapter, Quantaray (Sigma) zoom, a very sharp JC Penny 135mm F/2.8, Sears, Mamiya, and more Pentax 50mm lenses. Of all the 50mm lenses I like the SMC Pentax-M the best. The Takumar is too soft for me but will keep it for show and tell. The Tamron 90mm macro is the sharpest lens for close up work and I would recommend it for any camera. The Pentax 18-85 is very sharp and my favorite walk around lens. For serious zoom I have my D750 200-500 with 1.4 teleconverter so I will not be looking for quality long lenses for the Pentax, at least for now. Attached is a photo taken with the lowly $15 Sigma 100-300 at 100mm, F8, ISO 1250, 1/3200 sec. I obscured his face.
