A sad day...........
The K-5 could work too - just keep trying to find a solution, they're definitely out there. I sold my K5...... ONly kept the K200 for sentimental reasons. I think I know the issue. WIndows 10 won`t save the file without appending .txt and I can`t find a way to stop it doing it..... I`m getting re...

Don't underestimate your "lesser" lenses
Going through some photos taken in the Lake district earlier this year I spotted a bird of prey in the trees on one image - so I've had a go at enlarging it just to see how much detail I could pull out. The result isn't that great as an image but it was only when I compared the crop to the original ...

Don't underestimate your "lesser" lenses
That's very impressive! By coincidence having just seen what SRS are asking for the new Ricoh DFA*50mm and rashly supposing it is unlikely to outdo (say) the DA*16-50 by much where IQ is concerned, I thought I would compare my old manual Pentax 50mm f1.4 against the DA*16-50 and the DA*50-135. I wa...

Help selecting ultra wide lens
Have you considered the Samyung 14mm F2.8 ? It is manual focus, but the DOF also takes care of a lot of it, just set it to F8 and shoot. Somewhere around £330 new from SRS. You'll have to factor in it'll effectively give you a 21mm lens with the crop factor, but the Sigma 10 - 17 will effectively...

Help selecting ultra wide lens
Thanks for all your help much appreciated. Interested in your comment Algi re k20d. I suspect I would notice a difference in low light performance and speed of focus, but in terms of image quality for a properly exposed photo on tripod? Stuart

Help selecting ultra wide lens
There's a big leap in image quality. overexposed shots can easily be recovered. I've managed to pull back 5 stops once or twice. Crops are easy without much loss in quality. Higher ISO possible. The Samyung 14mm F2.8 mentioned by Chris is a good alternative, but not reported to be FF like they sa...

Blackstone or Firefly for the Irix 15mm
After months of soul searching for a super wide angle lens for my K1. Still cant bring myself to pay the Pentax 15-30 price. Though I don't doubt its capability, as a lens. Its also auto focus with a more sensible filter ring size. But the reviews of the Irix 15mm manual lens are receiving mor...

Problem Focusing with Pentax SMC DA Series 50-135mm f/2.8 ED IF SDM
I recently bought this lens after reading terrific reviews. I am having trouble getting the subject of the photo to be crisply in focus, and I have never experienced this before. I am using the lens on a Pentax K-S2. I have both the lens and the camera set to AF mode. Any suggestions as to what ...

Problem Focusing with Pentax SMC DA Series 50-135mm f/2.8 ED IF SDM
You can't go too far wrong to be honest. Take a shot as you normally would and take another with live view. Preferably using a tripod for both as this will eliminate some other possibilities. Check the focus accuracy of both. If both are out then you have a problem with the lens. If only the vi...

Problem Focusing with Pentax SMC DA Series 50-135mm f/2.8 ED IF SDM
I have this lens, by and large it is very accurate at focusing on both my K-3 and K-5iis, but has required some fine AF adjustment on both. Also, in common with many other lenses (and camera bodies) it's a bit more hit and miss in low light, something I've noticed most when doing gig photography wh...

In which case, you'd simply set it back to default and you're back to square one, surely? No better - or worse - off than when you started. You are correct of course. But call me old fashioned, I have always found it best to establish the actual fault first before attempting a fix.

. I now know how to figure out whether i need to adjust up or down. The basic question i have is HOW to make that adjustment. I see it on the C4 menu screen (#27 AF fine adjustment) but can't figure out how to move it + or - on the scale. The 4 way navigation bar moves the menu to #26 or #28. H...

Tamron SP 90 macro or Pentax 100 WR macro
Hi, I currently use an Olympus M4/3 OM-D E-M10 mkii with an olympus 60mm 2.8 macro lens for my shorter reach macros. For more distant stuff I've been using a sigma 180 F3.5 Macro on a K3, but I've added a Pentax KP recently and have started using my FA 100 F3.5 macro for the shorter stuff again (bec...

Tamron SP 90 macro or Pentax 100 WR macro
I find the Pentax 100mm macro gives excellent results and as Jak says works well with the Pentax AF160 ring flash. It zooms in and out to focus and the front element with the filter thread doesn’t rotate. I only wish it had a silent motor built in as it can be a bit slow and noisy to focus, and the...

Tamron SP 90 macro or Pentax 100 WR macro
Can recommend the SMC Pentax-D FA 100mm F2.8 Macro (mine's the non WR version.) Goes to 1:1, FF compatible and the Pentax ring flash is designed to fit on it. And yes it can be manually focussed. It's such a great lens I've got two of them! (Open to an offer for one of them!) You may find you c...

Tamron SP 90 macro or Pentax 100 WR macro
........ I see the pentax DFA 100 (not WR) had a focus limiter, but I don't know if it had manual focus override. Thanks I've just re-read a review of the DFA 100 (not WR) and it appears it doesn't have a focus limiter but I can't edit my original post. It is the FA 100 that has the limiter, but ...
