Sharp Long lenses for my K-30
Anyone have any feelings for how the Sigma 120-400 compares to the 150-500, in terms of IQ and of handling? I've used a few different zooms in 70-300 range, and struggled with responsiveness (mostly with AF bouncing), so might push the boat out a little bit given SRS have some pretty good deals o...

Sharp Long lenses for my K-30
The DA*300 is a stunner and I can't bare to part with it, but I spend a lot of time running around trying to get back far enough, quite often, I can't. A zoom will solve that and also show you which focal length you use most often so your next purchase can be an informed one. Sharpening in post? p...

Sharp Long lenses for my K-30
I think the answer to the OP's questions depends very much on 'how much to spend'? For me, there is nothing to compare to the Pentax 55-300 in IQ terms for the money, a DA L will only set you back about £200 or even less if you shop around. It is in a different league to the Sigma 70-300. The Sig...

My new aquisition.
Today we celebrated my birthday and the grandchildren came. So I made some portraits in our lunchroom with this lens. But i screwed a soft focus in front of it. Here are a couple of the results. Both pictures where taken with natural light. Next time I try it without filter. My Grand daug...

Tamron 17-50 non-vc
It should be good. Beating the 18-55 and getting close to the DA35. (rebuy the DA35 ;) ) Check the front element isn't loose, this affects focus. Try calibrating front back focus adjustment. I've had mine at +8 and +max too. Even after a service. I last did mine pointing about 3m from a...

Tamron 17-50 non-vc
Thanks Doug I think that the lens just doesn't do it for me as the other lenses mentioned do. The focus seems fine- I think it's the lack of contrast compared to e prime. Cheers Mac

Tamron 17-50 non-vc
The DA35 is softer than I anticipated at 2.8. The Tamron is sharper than I anticipated at f5!!!! Anyway I could probably do with calibrating them both at the same time and doing it again. Camera on a tripod, 6 feet away from the books, Live View focus on the Patrick Suskind book, I retook the...

Tamron 17-50 non-vc
This lens is a funny beast. It's sharp even wide open, with great contrast and capable of producing pictures with a nice 3D "pop" However... 1. Many copies are said to front focus or back focus, and perhaps by different amount depending on the focal length it's set to 2. There is said to...

Tamron 17-50 non-vc
I had no issues with mine Simon, it was sharp as a tack, but I have heard others with front / back focusing. May be worth a calibration?

Sigma 70-200 F2.8
After being just too late to acquire one of the two or three Sigma 100-300 zooms which have been sold on the forum in the last week or so, I have bitten the bullet and splashed out on a Sigma 70-200 F2.8 zoom, which on my K5II will give me an effective lens of 105-300 F2.8 I have also found out tha...

Sigma 70-200 F2.8
I'm fortunate to have both Sigma's and they are outstanding, plus focus speed is really good on a K5ii :-)

HD PENTAX DA AF 1.4X AW Rear Converter
Well the TC arrived from SRS and took it out for a quick spin along the lane today. Its focus lock on seems much more positive then the tamron I had before but this could be also down to the firmware upgrade recently, but it works. The build and fit is better then the tamron also. There does no...

This was a previous attempt (cropped and PP'd of course) but last night I just couldn't seem to get it in focus (manual).

HD PENTAX DA AF 1.4X AW Rear Converter
Thank you Ralph for taking the time to do some macro tests. The closers macro shots are hard to compare simply because they take on a different "look" when so close, but they do still seem very good quality. The slightly further back shots are probably a better comparison for me, and they do look ve...
