Pentax K 400mm

First post other than a hello post. Photos was taken with a Pentax K 400mm. This is a lens that I have a love hate relation with. At time I can not asked for more and other times it blows. Was going to post in a thread on the other forum but it got locked so here I am. That and this forum sent me a happy birthday. Also testing if I can load photos as I been meaning to post.

I notice that the first image shows some of the dreaded Purple Fringe because of the light background. I find the same with my M 400/5.6. I think it is the same optical formula and coatings as the K version. It just focuses a tiny bit closer (5 m/16.5ft). I'm still using the lens. It can resolve some great pictures in the right circumstances.

well, that's the problem with old telephoto lenses. If the conditions are right they outpurple just about anything I've seen. Even renown Tamron 70-300 sometimes seem like purpling amateur against my copy of K400. But if you know how to use it (don's shoot against the back light, stop it down [sometimes not necessary] and keep good shutterspeed), it's very rewarding:

Yes it does resolve well in the right circumstances. Still learning to work around its weakness as its my long lens at this time.

Yes, I have a Super Albinar 400/5.6 that will PF badly in high contrast areas. The good thing is, Photoshop makes it all go away quite easily.
