A short walk with Pentax-A lenses on K-1
These are super images and your comments do indeed echo what Pentaxians know. Leave the "in Poland" out of it. These particular ones are scarce lenses - anywhere. The simple A 135mm is a nice lens but an A*135 !! ( envy, envy). The other point about them is that from the time they were made, right u...

A short walk with Pentax-A lenses on K-1
It is a genuine pleasure to share my humble thoughts and photos here as - compared to many other busy and buzzy photographic websites - this is a temple of tranquility. You mean we have only a handful of members...!! But small can be beautiful. Lovely images and some very nice lenses. As has bee...

A short walk with Pentax-A lenses on K-1
An enjoyable post (and Blog images) - As others have said these are pretty rare lenses and they still hold up well against modern lenses in many situations. The A*135/1.8 is probably the rarest, but my favourite is the A*85 - I've had several copies over the years and I keep selling them off after c...

Telephoto zoom up to 300m recommendation
I use both the pentax 55-300 AND the Tamron A17 70-300. They are both excellent. If anything, the Tamron has the edge when it comes to heavy crops. I also have the Pentax 55-300 ED PLM which can produce amazingly sharp results BUT you have to focus with absolute precision or it will auto focus on so...

Telephoto zoom up to 300m recommendation
I too have the excellent 55 - 300mm PLM, very fast and silent with no focus hunting on my K3II . (It's F5.6 at 250mm) Most recent photos in my gallery on here are with it. I've finally this month moved to using the AF button as it gives me single and continuous AF all in one. I've never thought the ...

Want to buy A 50mm SMC LENS
I have a couple 50mm lenses that I could part with. Pentax A 50mm f1.7 or a Chinon 50mm f1.7. I think I also have a Chinon 50mm f1.9 The Chinons will cost less than the Pentax, but it depends on what you consider to be a good price. All are manual focus. PS There is also one here:- https://www....

I have a manual focus DA50-135. Lovely lens but have not got it fixed yet. Rather begrudge paying to get it fixed. I also have the DA200. This one is full AF and has never had any problem with the SDM. Definitely one of Pentax's best lenses, touched by the angels!

SDM Failure
:(:oSorry to hear about the problems experienced by Phil, Peter and Philip. I will inevitably post a message here if the SDM motor fails in any of my lenses, it's perfectly understandable that users do this. When everything is fine and ticking along nicely, it's not newsworthy. On the other h...

SDM Failure
Guys, fresh experience here with my already ex 50-135. I've sent it back today for replacement. Well, bought 3 weeks ago from B&H. I've sent email to support team prior purchase asking them to check the lens if its production date is relatively new. Their response was quick explaining that they ...

SDM Failure
Hi Lev Sorry to hear of your SDM issues, some of which also affect my DA*50-135 and some of which also affected another SDM I used to own. The biggest frustration I have is not the motor failing (although I think it is on its way out as it takes longer and longer to 'wake it up'). No, the bigge...

SDM Failure
David how do you think, is that a camera/lens combination problem or just lest itself? Hi Lev I think it is a bit of both, mostly the lens design, specifically the motors, but it also is affected by the camera. For example, regarding my DA*300, which also a SDM lens, it focuses much more accurat...

David thanks for your replies, yes I got just couple of days before I make final decision. I really didn't know I would start thinking all over again. Well, your DA* 300 is prime, we both know that its focusing mechanism is less complicated and of course should be more accurate but we didn't signed ...

Well, what to say, would you buy it again? I mean, now I have a choice to return if, replace it or exchange it to something else. I can't see other WR portrait lens out there with similar IQ rather than 70-200. Did your lens behaved like that when you got it or it started to do so later? Hi Lev T...

DA* 50-135 loose focus ring
Hey folks, looks like my troubles with new gear continues... I've just received brand new 50-135 and it has loose focus ring. This loosness feel is more noticable to the one end of infinity than another. When I rotate the focus ring and then rotate it to opposite direction, the inside ring in the...

DA* 50-135 loose focus ring
Send it back as you'll only regret it later if you don't.

DA* 50-135 loose focus ring
If you can, compare it with another 50-135, although that might be difficult where you live? What you describe sounds just like mine, and it works fine. I suspect what you're experiencing is the working and sound of Quick Shift mechanism.
