Pentax Lens refresh...
If I'm honest I lost interest in what Pentax/Ricoh do a while back. Sort of know how you feel there Mike, When they don't provide you with waht you want for any length of time, well you just go off and start using something that does what you want, like you have done! Can't blame you at all for that...

Pentax Lens refresh...
Nice to see a good quantity of re-engineered and new product being announced in one go. I heard a rumour from a chap at a Pro Centre not far from here that Pentax will most likely stick with APS-C for DSLRs a few weeks ago and this appears to back up what I heard. Great to see investment coming th...

Takes a lickin but keeps on tickin! I'm going cold on Pentax Forums reviews due to some underlying Pro FF but somehow anti Pentax bias that seems to be going on there? Don't get me wrong they are not as guilty as some but they just seem to be banging their collective heads against the same bit of...

The DA15 is renowned (some might say fabled, revered) for the starbursts it produces. from the upgraded lens seem to confirm that these starbursts have been minimised in line with intentions: "2. Round-shaped diaphragm for beautiful out-of-focus rendition All lenses feature a completely round...

sigma 18-35 f/1.8 review
I read in one of the magazines some months ago that big camera manufacturers are unlikely to make similar lenses partly because they might demonstrate focus issues with the cameras. Particularly as most cameras only have limited numbers of suitable AF points for accuracy at wide apertures, losing a ...

Are manual lenses really any use ?
Last night at my camera club. I was given a Pentax MV1 and four fully manual lenses. Should I be looking to use any of the lenses on my K5II or K7, Or just dispose of them. The lenses were a Vivitar close focus wide angle 28mm f2.8. Pentax M 50mm f2 Super Paragon 80-200 macro F4.5 Super paragon...

I have a Komine made Vivtar 28mm - not the close focus one but it focusses at the same distance??? - I like it a lot once stopped down a little :D

try them for video.... I use a lot of M and A series lenses just for video and as back ups for my af lenses for stills or studio work. .

This is the Ricoh pin on my Clubman 28mm f/2.8 manual focus KA mount film camera lens - This lens got stuck on my K100D. Fortunately, after a lot of jiggling around (and also jiggling the lens and camera), I managed to unstick it, and I won't be attaching it again! However, Pentax manual le...

Are manual lenses really any use ?
Does anyone know if any of those non-Pentax lenses has a Ricoh pin because, if it does, it might get stuck on a DSLR body. No they don't. Which is all well and good. I have got a M50 f1.7 which I hardly use so I have just fitted to very cheap extension tubes and get excellent macro shots. I also ha...

Are manual lenses really any use ?
Stuart's Vivitar close focus wide angle 28mm f2.8 would certainly be worth trying out, John. The 28mm is not really a wide angle on a DSLR, so it might work OK. This is a shot taken last year with a 28mm Pentax-A lens, about 2/3 crop Jpeg SOOC, EXIF intact, unprocessed except for re-sizing - P...

Oops:oops: - I noticed I spelt Vivitar wrong in my earlier post:oops: The Komine versions start the serial number with 28 - the close focus version is meant to be the best of them :D Here's the link to my photo's with the one I have

Are manual lenses really any use ?
The short answer to your question is a qualified 'yes'. It depends on whether you feel the need or the urge to try something different. Here's what I use my manual lenses for: - Pentax M 28mm F3.5 - Landscapes (mainly) on K-5, K-5IIs and K-01, or reversed as a macro lens on K-5/K-5IIs - Pe...

Are manual lenses really any use ?
One point to mention is that since acquiring the K-01 my manual lenses have a new lease of life. The focus peaking on the K-01 is a magnificent aid to focussing with a manual lens and makes it as easy as AF for me +1 for this. Focus peaking in live view is very cool. You can press the middle ...

Are manual lenses really any use ?
a set of tubes from Ebay to use with my A50 1.7. :) I used these with that exact same lens. Check out 'focus stacking' if you're going to get into that, as the tubes can contribute to a crazy narrow depth of field. Sometimes you'll need to use wide apertures to let in enough light, but that produc...

Any big differences between the DA 50mm and 35mm lenses?
The 50mm is very simular in construction to the 35mm, I would say it's a little better as the focus ring feel a bit nicer. The 50mm is also sharp, it's not so sharp at 1.8 but i dont think thats a bad thing. It does not suffer from purple fringing as much as the 35mm either.

Any big differences between the DA 50mm and 35mm lenses?
Sorry, is 2.4 an F2.4 lens or 24mm lens? Very sorry Barrie, I wrote this very quickly late last night. :oops: Was rushing to get the question out there before I headed to bed here in New Zealand. I had just sold my manual Pentax-A 50mm f1.7 version, which had been 'de clicked' which was supposedl...
