My favourite is the Sigma 100-300 F4, but I have yet to try the 55-300 PLM on the 2 K-3's at an airshow - and I will be very interested to find out how good it is in the "real world" (from very limited testing, I know it's blindingly fast to focus - but I'm waiting to find out if the tracking is an...

My 55 - 300mm is on a K3II for the last year and a K3 for several months before that.Tracking straight at you remains poor. Side to side it's fine. See Buzzard hunting at head of my gallery on here. i've used this lens back to my whale and dolphin pics in the Caribbean in same gallery. It was foreig...

Compare and contrast: HD Pentax-D FA 24-70mm F2.8 with HD Pentax-D FA 28-105mm F3.5-5.6
Thanks for the advice guys, it has been very helpful indeed: I see the disadvantages in terms of speed, width, and weight, John, and given that I seldom if ever take sports or theatrical type photos, I guess the 24-70 offers less than I would benefit from. Rob, although light is sometimes an i...

Which way do Tamron zoom rings work?
Yeah, may sound petty, but I've got other things to be thinking about than which way do I have to turn this one. Tamron pros seem to be price, zooms the same direction. Cons are some references to front/back focus requiring calibration (hope it's linear and can be adjusted), plastic build qualit...

Which way do Tamron zoom rings work?
I think the Tamron 17-50/2.8 zooms the same way as Pentax while the Sigma zooms the opposite way. For what it's worth, if it's within your budget and you don't mind the extra size and weight, the Sigma is overall a better lens, though the Tamron is no slouch. Argh, lots of info to digest. An...

Which way do Tamron zoom rings work?
Yes I’m strongly considering the Sigma 17-70 having read all these comments. It’s f2.8-4.0, but I like the idea of the more versatile focal length over the 18-55 kit. A huge amount of posts re the Tamron back/front focussing inconsistently throughout the zoom range, which you can’t fix with a...

Which way do Tamron zoom rings work?
You should always check any new (or used) lens for focus issues and edge-to-edge performance either before buying or at least before your option to return it expires. This goes double for third-party lenses such as Tamron or Sigma - if you get a good one then it should be fine but I've experienced ...

Vintage Lens Reviews
Yellowing and thorium aside, the f1.8 version takes magnificent pictures. The only thing that detracts (vs modern lenses) is the lack of auto focus. As I said, my copy is really beaten up but the glass is superb.

I bought an F 100mm macro not long ago. It does quite well but I got cross with it a day or so back (a) the AF and (b) the silly thin manual focussing ring. I screwed 20mm of manual extension tube onto my ancient Takumar f4 50mm macro and it beat the pants off it ! The gallery photo of a button was ...

Sigma 105mm 2.8 EX Macro
Does it have the auto/manual focus ring on it? That needs to me in manual focus mode as well as the K5.

Sigma 105mm 2.8 EX Macro
I hadn't changed the focus mode on the camera to manual, lens feels just fine now. Thanks for the info, this is my first DSLR and believe me I'm still learning. I went from a manual Pentax MX to the K5 and it's a little bit overwhelming. Regards, Sam

If you want to try the Sigma 24mm f2.8, I am thinking of selling mine. I'm thinking of asking £30 inc p&p. It's the manual focus version. It's not in amazing condition but still works great.

Or, I think about a Samyang 24mm that I've just seen at a good price... argh:? I have a Samyang 24mm TS and it is very sharp, BUT no Samyangs have electronic connections to the body so manual focus only.

The 24mm TS is a one off (as are their cine lenses) in that it doesn't have an 'A' setting. The rest of the DSLR line of lenses are also manual focus but do have an 'A' setting.

Lens repair in East Midlands?
Does anyone know of anyone that can do repairs on old manual focus lenses? (Or would anyone on the forum like to have a go for me?!) I was going through some boxes in the cellar, and sadly found that my lovely K 135/2.5 had been stashed in the pocket of a bag I had been using to carry my flash ge...

Should I buy a Pentax-A SMC 50mm F1.2 Lens?
Two shots with the A50/1.2 fitted on the Pentax K-5. I believe that catch-in-focus was used, but still it is hard to nail focus. I guess it is due time to do some more practicing with the A50/1.2:) f1.2 by , on Flickr f1.2 by , on Flickr

For wide aperture lenses the Canon Ee-S Super Precision focusing screen is a big improvement. Unfortunately you have to cut it down yourself :lol: 52 page thread :shock: https://www.pentaxforums.com/forums/115-pentax-k-5/142241-best-screen-ever-manual-focus-canon-ee-s-52.html --
