Focus stacking
A few months ago, I saw some fantastic landscape images shot using focus stacking. Until then I had considered the primary use of this technique to be macro work. I've been having a (brief) look at using focus stacking for landscapes. The obvious problem is movement in the subject between frames - ...

Give zerene stacker a shot too, it's the best out there Not exactly cheap though is it? I would certainly want to ensure that results were significantly better before shelling out $90 + tax

The pp does not look too bad so will give it a go - have downloaded Combine ZP - now just need to figure out how to use it! One thing you need to look at (in the help section) is how to change the defaults for sharpening and added contrast. By default, both are a bit over the top. Andrew

Lens or Body the cause of good/bad autofucus
Combination of both, i can tell you from my experience the following K-5 tamron 17-50mm regular focus hunting despite lighting conditions, misfocussing common K-5 da* 16-50mm less focus hunting, misfocussing less than tamron K-5 mkii da* 16-50mm very rarely hunts, very rarely misfocusses Whe...

Lens or Body the cause of good/bad autofucus
Is the decision Pentax to Pentax, Pentax to Canon or Canon to Pentax? I started out with pentax and to be honest was very happy with the kit lenses. I bought my first big money lens from onestopdigital for my pentax but they sent it in canon mount. It was too much hassle and cost to send back so I ...

Lens or Body the cause of good/bad autofucus
I find the lenses in my bag all different on my K5 but then they would be. My DA15 Ltd is fine. Not much focusing going on there anyway at that focal length :-)I like to use it in manual anyway given it actually has an aperture scale engraved for focus. My 55 - 300 DA hunts around less (but st...

it actually has an aperture scale engraved for focus. I didn't know the aperture scale could be used for focus.:shock::lol::lol::lol: I think you meant focusing scale.

Lens or Body the cause of good/bad autofucus
I think Gary (Cabstar) and MikeP have hit the nail on the head. The K-5II variants are much more accurate in the focussing dept. than the K-5 Mk1 and also lock on more reliably. This is not just a minor difference - it transforms the AF performance, especially in tricky conditions. All of my AF l...

Lens or Body the cause of good/bad autofucus
Out of interest, you refer to the 50-135 as a 'poor af performer'. I presume you are referring only to speed? Accuracy has always been spot-on regardless of body. Sorry I am generalising, from reading here and on the other various forums I actually mean everything like the failure rates of sdm, spee...

Lens or Body the cause of good/bad autofucus
Agreed, when doing my research on this lens I find it really hard to find images taken with the 50 - 135 but when I do they are usually excellent quality. Most posts you find about this lens are very old posts which tend to focus on the earlier models and sdm failure. Has anyone used this lens for...

Lens or Body the cause of good/bad autofucus
I have had 3 or 4 copies of the 50-135mm in the last few years and sold them all after a couple months ... really is a love hate relationship with that lens for me, I love the IQ but hate the AF speed and so I always ended going back to a Sigma 50-150mm f2.8 HSMII. I recently purchased another on he...

Lens or Body the cause of good/bad autofucus
The 50-125 does have a huge focus throw to contend with though compared to other lenses in that range. I bought mine secondhand four years ago maybe even five years ago nd never had any issues with it apart from when I somehow snapped it at the mount....

Lens or Body the cause of good/bad autofucus
Given that any single lens requires a different amount of 'fine adjustment' on different Pentax bodies that have the facility to make said adjustment, I'd say it's the body, not the lens. Of course, if the camera can't make enough adjustment to obtain good focus at any setting, you have to questi...
