Sigma AF hunting issue.
Last Thursday I notice the same problem on a Sony /Tamron combination. A few quick tests showed it was over F8 when the problem arose. Further checks showed the problem was there with two out of three bodies (the oldest ones) So back to the original combo and changed the AF setting from C t...

Probably my biggest regret
As some of you will know my philosophy is to try as many Pentax lenses as I can, but the process is quite expensive with some lenses being quite rare and sometimes a little (or a lot) over-priced. To fund the philosophy I've parted with a number of superb lenses, some of the very finest going to mem...

As a beneficiary of some of your selling to fund a new lens, I can only praise your philosophy of high quality recycling. :wink: It's interesting that you missed the 'feel' of the lens. If I had to get rid of all but one of my six (eek! :shock: ) 1:1 macro lenses, the one I'd keep would be the Ir...

Just as no one lens can do everything specs-wise (speed, focal length, sharpness, bokeh, size, weight etc) no lens can do everything in terms of user satisfaction - sometimes you need AF or peak sharpness to get the job done and sometimes you just need the feel of a well, designed and well-built man...

Probably my biggest regret
Anyone compared the Pentax K 85/1.8 with the A*85? Funny you should ask - but that's what I've been doing over the last few weeks! With these 2 lenses it really comes down to what is important to you as the photographer rather than just comparing the technical capabilities of the lenses. That mig...

150-450 mount snapped off!
Yes we were in the back of a land cruiser being driven off road. This was on about day 10 of the safari but i did not appreciate the ground was much rougher than anything we had driven on previously. Luckily had the 55-300, 70-200 and sigma 50-500 with us so the loss of the 150-450 was manageable wi...

150-450 mount snapped off!
I always put the camera on the floor behind the driver's seat so that it will be protected if I have to brake hard - Murphy demands too much care when putting kit on the back seat, no matter how strapped in it might be!

Question regarding the Power Zoom button on FA and FA* lenses
From recollection - there is a standard for FA lenses and a different standard for FA* - the FA* switch was flush with the lens body while the FA switch was proud of it. Thanks Peter, that was what I had at the back of my mind - I doubt I'll find a FA* PS switch at a reasonable price so I'll probabl...

DA 70mm 2.4...is it me?!
Hello all I am struggling with this lens..... AF is hit and miss. When it hits it is great...otherwise... I have attempted to callibrate the lens...shooting one of those targets, tripod mounted, base ISO and wide open at a distance of about a meter. I took shots, in JPEG, at all adjustment...

Cathedral and a library on a budget
Still a bit unsure as the f4 on the 16-45 may not be fast enough and a tripod just doesn't work for me. I'm more of a see, frame, focus, shoot kind of person. My other problem is that wide angle is new to me so it may be better to try cheap to see if i like it. But then I might get crap photos o...

Cathedral and a library on a budget
Found my Samsung D-Xenon 50-200mm ED yesterday in an old camera bag Along with some old sandwiches curling at the edges and an ancient flask of by now cold coffee??? :lol: On a more serious note, have you tried calibrating the KP's AF for the D-Xenon? There's sample variation in both cameras and ...

The D-Xenon seems sharp enough on my K200D? So will definitely try fine focus adjustment on the KP

Cathedral and a library on a budget
The D-Xenon seems sharp enough on my K200D? So will definitely try fine focus adjustment on the KP That looks OK to me. I owned a Pentax DA WR 50-200mm for a few years and was never very happy with the sharpness, even stopped down to f/8. I switched to taking an older M-series prime (135/3...

Using Pentax converters
Firstly I admit I am posting this partly because I am currently selling one of my Pentax converters (a rear converter A 1.4xS - I have 2 of these, and am keeping one) - but it's mainly to demonstrate a piece of advice that I have given to forum members whenever I have sold a converter or discussed u...

Using Pentax converters
...For which lens(es) do you think a FF version should be optimised? Presumably it isn't possible for a TC to be equally good for all lenses. And a FF TC would undoubtedly be pixel-peeped by devotees of the art. Steve The Pentax design philosophy back in the A series days was to offer two convert...

Do you NEED to buy expensive lenses? .... A comparison.
What to do when it's freezing cold, wet and foggy? You stay indoors and play with your camera! I saw lots of water droplets on a bare cherry tree right at the end of the garden so I put a DA*300mm on a K1, on a tripod looking through the patio windows. Since nothing was moving, I dialed the ISO d...
