Bad review for DA* 16-50mm

Yes, it does look a little strange. Is the fence at the left further away than the fence on the right? It certainly looks so, if the fence panels are the same size :) If so, the effect will be more pronounced with the closer post. I understand what you are getting at but it does seem a bit extr...

Bad review for DA* 16-50mm

I would love to own another DA* lens, but just cannot justify the cost involved for so little improvement. Review after review seems to back this. I think Pentax seriously need to review this lens & its cost before I would consider buying it now...

Bad review for DA* 16-50mm

'Tried and tested DIY fixes' - hmmm, possibly not what you want to be reading about when you are thinking about spending a very large amount of money on an SDM lens... You might conclude screw focus isn't such a bad idea after all :lol:

Bad review for DA* 16-50mm

I have the DA* 16-50 and DA* 50-135 and DA 12-24. The only lens that demands AF, in my opinion, is the DA* 50-135. That's the sports lens. It's also the lens with the broken SDM auto focus. My 16-50 is working flawlessly. Grumbles loudly. Wide to normal focal length lenses can be used quite hand...

Which quiet focusing lens for K5

Hmmm, i did not consider the DA 17-70 because I thought the Sigma 17-70 is was a better alternative ( smaller/lighter/close focus) I must say, I am leaning towards the 18-135 WR

Which quiet focusing lens for K5

That is just overt temptation Gwyn, a carrot dangling in mid air....I'll look forward to when you list it in Classified Ads! :) Did you have to give your review copy back then? That's a bit mean!

Pros 'n' Cons

Oh bugger, I have a Pz-AF 2X TELEPLUS MC7 and the motor whirs but overshoots the focus and never finds focus. Do you think I have a duff one? It also used to stutter its way to focus with a screw drive AF lens.

18-55 & 50-200 kit lenses

Personally I would skip the 50-200 and go for the alternative suggested by John, or one of the fine older lenses like the F 70-210mm. The 18-55mm is bundled for next to nothing, and if you get a good one, is pretty good. Unlike a lot of people I haven't been especially happy with my copies when scr...

How can you tell...

If you look at the back of your Pentax lenses you will see the construction and be able to compare it with any other lens. A K mount will be quite distinctive. As for which type, the essential bit will be are there electronic contacts or not. If there are, then full metering will be easy with DSL...

How can you tell...

I'd second what dangermouse said. Got a manual lens a couple of months back with the dreaded pin on, nearly broke my camera trying to get it unstuck :P But, at least it's realy easy to remove the pin http://www.theatreofnoise.com/2008/05/ricoh-lenses-on-pentax-cameras-ricoh.html - great guide...

Lens seems soft after repair

I recently had my FA77 Ltd lens repaired. A pin in an aperture blade had come loose. The repair involved replacing the front assembly. Before the repair I was very happy with the lens but now it seems to be slightly less sharp than before. I tried adjusting for front or back focus but even after...

Lens seems soft after repair

Focus chart shots look ok to me although I now have neck ache from trying to look at them sideways :D As for the socks, bit of a difficult subject to judge the lens on really.

Thanks for your time everyone. Sorry for the slow reply but because of the time difference I am asleep when you are awake. Mike P. Point taken and the problem is I do not have like for like images to compare. Your avatar is great. Is that your cat. It looks like a British Blue which is my ...

Lens seems soft after repair

m42geo Thanks for the lovely images. They look a little sharper than mine but I do not know what your pp was as I haven’t got a clue how to look at somebody elses exif data. My images were downloaded into lightroom with only the preset pp. Did you look at the full size images. The old woman si...

Lens seems soft after repair

m42geo you may be right! One of the things a noticed when I did my focus test was that the focus moved to front focus after f3.2 so if you look at the focus charts there are the images taken at f3.5 and f4.5 are front focused. I was told that this is normal and that all lenses do this to a certa...

Pentax SMC M 50mm f1.7

I saw one of these revered lenses on Fleabay about a week back. I already have two 50mm lenses - both Rikenon, a f2 and a f1.7, which I am quite keen on. The MTF charts on Pbase also suggest that the Rikenons are at least competitive. So why bother ......... Well, the auction listing did say t...

Pentax SMC M 50mm f1.7

Can you post the comparative shots and explain them? Errr ........ as I rushed when I took the shots yesterday, I had another go today. This time, I took several shots with each lens, refocussing each time - and then picked those that seemed the sharpest for each lens. After doing that, the differe...

CZJ 135mm f3.5 - Charity Shop Bargain?

Hi all, Decided to pop into the local charity shop's while in town the other day, I rarley find anything that good, but I think this is one of the times I'm glad I went in. Picked up a Carl Zeiss Jena 135mm f3.5 / M42 Mount. To be fair I didn't realy know anything about these lenses, but it di...

CZJ 135mm f3.5 - Charity Shop Bargain?

They're really nice - I've got one. Sharp, excellent contrast and nice bokeh (and a much closer minimum focus distance than most 135mm lenses). If you want a 135mm prime, I don't think you'll do better without spending a lot more (if it's in good shape optically). It's not as well built as Penta...

CZJ 135mm f3.5 - Charity Shop Bargain?

I got one the same way for £5 :). It's a nice enough lens, not a focal length I use much though. They're very common because they used to be sold with Praktika cameras back in the day.
