(This is my monthly summary from the Single in May challenge where I used the K135mm f/2.5 lens and is cross-posted from there. Chrome users may well have to follow the links unless you have edited your security settings. Firefox users should have no problems.)
May is often a busy month for me as I have to do a lot of grading. I used to have a trip to the US in the middle but the event was cancelled because of covid in 2020 and hasn't been reinstated. As a result I had a lot of "safeties" including one or two terrible ones which I'll gloss quickly over. The main issue I have with the K135/2.5 is that it is not very close focusing. As a result, my extension tubes got a lot of use this month, often just the thin 13mm one which is enough to bring focusing down to about 1m or so. I have no idea why, but I seemed to have more problems focussing the 135mm using the viewfinder than I did with the K120 earlier in the year. Whenever I could (basically when I could use a tripod), I used live view to refine the focus. Only once did I knock the dial when turning the camera on and accidentally set the focal length to 1135mm. I'm getting better at checking. I also think that the contrast etc. would be improved with a lens hood. I have an original appropriate plastic clip-on hood but one of the clips is not quite right and it tends to fall off, so it didn't get used much. Before I moved house I used to use a metal screw-in Takumar hood which was much better but I couldn't find which box those ended-up in!
All in all, it is a nice lens and I'm happy to have it and use it. It is nice and sharp when you nail the focus and quite bright. I suspect, however, that the K120mm might see a little more use on the basis of the two SIC months with these two lenses, Here are a few unremarkable images.
