CAn I have some DA* 300 pix????
Hi Alistair, I have just bought a Siggy 150-500 (non OS) from another forum member. The lens had barely been used, so qualifies as almost new, but is not the latest version. I don't think the 'OS' vs 'non OS' would necessarily make any difference with focussing speed (correct me if I'm wrong on th...

Optical Stabilisation Vs Shake Reduction.
I turned my OS as it's not so easy to turn off SR in th K-5 - good results so far. I was shown this by Blythman at the weekend. Press the INFO button on the back of the camera. highlight the shake reduction symbol, press OK and you can select on or off

Optical Stabilisation Vs Shake Reduction.
It's been available for years on Pentax via certain Sigma lenses. The 150-500mm is quite impressive and also useful for use on a tripod when 500 or 500+TC will still shake. I never though about it before, but it probably makes manual focus easier if the image is stationary. --

This is the lens I was talking about. I did tried using it, but doesn't recognize the focus, it just keeps flashing.

What is flashing? The focus confirmation is the Green Hex. at the base of the viewfinder, not the red square in the middle.

Pentax 50-135mm f2.8 SDM repair and difference in AF speed.
I recently purchased one of these off the forum at a very reasonable price due to it having no working auto focus. Thanks to the PU discount JPS repaired the lens for £144 (a saving of 20% on their normal price) and it was returned to me in just over a week. The purpose of this post? I just have to ...

Pentax 50-135mm f2.8 SDM repair and difference in AF speed.
Thanks for posting this. I have a 16-50 which hardly gets used as the 17_70 is far quicker to focus. The 16-50 does play up occasionally so I may well send this in when funds permit. Like mike I have the 60-250 which I would love to be faster as it would get used far more. It would be nice if ...

You can't go far wrong with the Pentax DA 55-300mm f/4-5.8. I got mine initially for bird photography but have also used it as a general 'walkabout' lens. It performs well taking 'falcons' in flight using the K-r's 'rapid fire' but its main problem is 'hunting' on auto focus near infinity. I u...

I would disagree to some extent with PeterKr's views on the 55-300. It is nowhere near as good as the Sigma 150-500 as a wildlife lens, even when you disregard the focal length difference. The 55-300 is a fantastic lens - very sharp and contrasty, but is poor for wildlife simply because it does no...

Im afraid the answer is simple. For sport and wildlife. At present, Change Brands. Though it pains me to say it. The Pentax systems dont focus anywhere near fast enough. Hopefully this will be rectified in the future.

For wild life and sports lenses
Hi, I too would like the big Sigma BUT I have to say that whatever Pentax did in their last firmware update (for the 560mm I believe) on the K5 it has certainly improved the telephoto AF of the 55 - 300 DA. Mine only rarely hunts now in a high contrast sky in spot focus and not at all against land b...

Stuey, what is wrong with someone wanting better tools? Are you still cooking the rabbit, that you caught with a trap made from stripped tree bark and a branch, on a fire that you lit by rubbing sticks together? :lol: You have a point guys it's not the fact of better tools I don't get its for the re...

Stu, I've told this story before. I nearly switched after seeing my first ever cuckoo late last summer. Myself and two other photographers both got shots of it sitting on a post. It then flew to the left. The two guys I was with got excellent in flight shots. I got a blur. I have no doubt that if I...

Sigma 8mm fisheye
Anyone had any experiences with this? Missus wants a fisheye and I'm curious to give it a go as well, there's one up for sale that I might have a look at - it's the f/4 EX DG version, so would work on film as well. Failing that, any other recommendations? This one's been done to death on the O...

Sigma 8mm fisheye
Ta all, and apols for delay in getting back to this. Just to recap, the Sigma wouldn't give the full effect due to it being designed for 35mm frame, would the 10-17 or is it simply that the 10mm angle isn't quite side enough? I've found a new 10-17 going for £370 which is tempting me, but if t...

The choices for telephoto zooms
Hi all Well, I bought the missus the Samyang fisheye, but now I'm looking at a telephoto for chrimbo! Ta to all for comments, most useful. Out of interest, are there any SDM telephotos worth considering? I bought a Sigma 8-16 with SDM, the focus is impressive but it's a bit waste don an ultra...

The choices for telephoto zooms
It's already been said above, the DA or DA L 55-300 is a magnificent lens for the money, it can't be beaten in its price range. I don't know anything about the WR version, but the originals are superb. Regards David Ta David - I'll look into the DA/DA-L. I quite like the idea of quickshift foc...
