Lens wanted.
Thanks regarding FA. I prefer the F and having a punt on ebay at moment. May get back to you if I don't win it. No worries - I was considering bidding on that one (as it's local to me) but I'll hold off :wink: The one Pwynnej has linked actually seems to be a fairly good buy - condition looks goo...

Lens wanted.
Thanks to all advice, on having second thoughts (and the fact that I do have a K series 135/3.5) I have cancelled my bid. Mike-P I had seen the eBay £220 one and it was on my watch list. My eyes will cope with manual focus for a while longer I hope. Thanks again. John

Lens wanted.

K20D IR Overpriced?
Morning Micheal It was Advanced Camera Services as well, I dropped it off in person the middle of April and got it back by courier the end of July. The service was overall good, i think delays in obtaining the parts plus their workload all contributed to the lenghty time. They do a CLA as w...

Wide angle question
Well... Back in the days of film, I bought my first wide-angle prime for a trip to Iceland. It was a 24mm. It took shots that I doubt would have been possible with a 28mm. But that was Iceland with huge and spectacular scenery, some of which you couldn't fit in a 28mm by stepping backwards (or you'd...

Wide angle question
24mm has taken over from 28mm as the standard wide-angle of primes and also starting focal length of zooms. Before that, long ago, it was 35mm. Both are fine if they meet your needs, and that will be something you'll need to decide, with the easiest way being to get a zoom that covers both, even i...

Wide angle question
If you take my approach then you'll buy anything you want (within reason and not above market value of course) give it a try - then if you like it you keep it, if not you sell it on here, on ebay or part-exchange it. You might lose a bit of money, but generally speaking you'll get back similar to wh...

K3 - Manual focusing
Hello everybody, I'm using some M lenses on my K3 and my question is: what is the best way to precisely focus manually. Ok, I know using LV and magnification option or viewfinder plus red spots and sound alerts (not every time precise). II'm missing my old K1000's focusing screen system. Are there...

K3 - Manual focusing
You can use a "focus trap" with manual lenses. You set the shutter to operate only when the suject is in focus, then you hold the shutter button down. The shutter will then operate only as your suject comes into while you turn the focus ring (not too quickly, otherwise the sensor won't have tim...

K3 - Manual focusing
"Catch in focus", as described above does a good job but it can fail just as much as relying on the bleep. There is no split screen option for modern Pentax cameras because the designers assume we will all be using their (mega expensive) AF lenses. Many manual lenses suffer from an ailment known as ...

K3 - Manual focusing
Have you tried the O-ME53 magnifying eyecap? It's not magic, but it helps when using the viewfinder for manual focus. Steve

K3 - Manual focusing
I did try a replacement focusing screen in my K-50. This has a circular diagonal central split screen area which was surounded by a larger microprism circular area. The split screen and microprisms certainly worked just like you had with film SLR cameras. However even when focus looked perfect with ...

Continuing the wide angle question
I recently purchased, as a bit of a gamble, a Sirius 18-28mm K A lens on the bay. Well, the gamble didn't pay off. The lens was, to put it bluntly, crap. Out of focus, dodgy exposure, and generally unfit for purpose. On informing the seller of this, prior to returning it for a refund, I received the...

Continuing the wide angle question
It's a re-branded Samyang lens from back when Samyang made the worst of the worst. I tried one out on my K200D many years ago and it was horrible. Compatibility is not the problem, the problem is that it's an extremely poor quality lens.

Minimum Focus Distance K-5 vs K-1
I currently use a Pentax K-5 and the Pentax SMC DA 35mm f/2.8 lens for a documentation and archival project for Wikipedia and a archival site called Radiomuseum on audio vacuum tubes. The K-5 is in pretty bad shape, so I'm planning an upgrade to full frame. E.g. the Pentax K-1. Will the macro obj...

Minimum Focus Distance K-5 vs K-1
Hi Kasper, I have a K-1 and the HD version of the DA 1:2.8 35mm Macro Limited lens. A fantastic lens I used on my K-50 till that camera broke. I've just tried it on the K-1 in 'Full Frame' mode at the minimum focus distance, it works fine, there is some vignetting but aside from that is works we...

Minimum Focus Distance K-5 vs K-1
The DA 35mm macro is designed for Pentax crop sensors, not full frame. However, as MikeInDevon has shown above, it will cover a full frame sensor but with light drop-off outside the area of the crop sensor. The minimum focus distance will not change, it is a property of the lens not the sensor or ca...
