Da 14 or 15mm
I actually sold my 12-24 & bought Unlockers 14mm. Didn't regret it for a minute, but then again I had the 10-17mm if I NEEDED to go wider. It was beautifully sharp, minimum focus distance was alot closer which I found a great boon in composition & it was more resistant to flare. Only you'll kn...

Da 14 or 15mm
the advantages of the DA14 for me are as you say, the extra close focus-ability which is quite handy for those dramatic wide angle close-up-to-distant shots that can be so effective. Good point from both of you. The DA14 focuses closer than any other wide angle for Pentax, at 17cm. The DA12-24 manag...

Converter or Not?
There's no substitute for trying these things out for ourselves. I've always been disappointed with converters and wondered how the Pentax ones would perform. However, the price has always been high and well out of reach. This test so far has been a bit severe, using the prime lens (albeit a good...

Converter or Not?
Ken, I think we now all have spots before our eyes....it's very close. So who can tell me what book cover this is? I'll give you a clue - it's the back cover, bottom left. :)

Pentax fa 50 1.4 usage
The lens will be perfect for anything as long as you can fill the frame with it. So some landscapes will be fine (in fact, lots), and groups of people as long as you don't mind standing further back. If space is tight, you won't get them all in. It's ideal for portraits. G

Pentax fa 50 1.4 usage
Sorry if this takes things a little off topic but does any one use any of the old manual focus lenses for there landscape work. I ask this because its an area I want to try and get into and there are some old lenses in a shop in Newcastle. I have both the 1.4 AF and the 1.7 MF 50mm the 1.7 cost me t...

Pentax fa 50 1.4 usage
I use old manual focus lenses for almost all my photos. I would rather have the 50 1.4AF than my 50 2 MF though, any day. But the difference in IQ/ease of use isn't worth the cost, to me. If I were you I'd sell the 1.4 and make a tidy profit on what you paid for it, or sell me the 1.7! :wink:

My 28-200 how many versions are there!
I never consider that an image is usable straight from the camera. They all need adjustment in one way or another to get the best from them. In the first and third cases here you are shooting in rather muted light, and you will need to adjust contrast. In the second case you are shooting agains...

Sigma 10 -20 vs Tamron 10 -24
Choose something with good hard contrasty edges to lock the AF onto. Bear in mind that this is a very wide angle lens and isn't a very wide aperture and it can struggle to find hard edges to lock onto - at least that's my take on it. It can be bitingly sharp. I'd add a couple of things to this, ba...

Problems with Sigma APO 1.4x DG AF teleconvertor
Hi, I have a Pentax K10D with a Sigma APO 100-300mm F4 EX DG lens and have bolted my new Sigma APO 1.4x DG AF on, and am having trouble with the auto focus. I've got it set on the "P" setting and AF.S, shake reduction is on. On the lens I have autofocus set and the ring set to A. When I ...

Problems with Sigma APO 1.4x DG AF teleconvertor
I had exactly the same problem with this setup (100-300 and 1.4x). I sent the TC back to warehousepexress, and they sent me a replacement. Replacement had same problem, so I sent it back to Sigma. They found a problems with some gears and fixed it FOC. Tim

Lens Comparison - Advice needed
Just downloaded the f/2.8 shot. I was going to say No. 2 looks nicest from this to me, No. 1 suffers from longitudinal chromatic aberation (see the green edge to the out of focus rooftop), and doesn't appear to be as sharp across the frame, although this may be because the focus was slightly furthe...

Lens Comparison - Advice needed
Based on these limited tests, I'd probably go with Lens #1. However, as I've found there's more to a lens than sharpness and bokeh (in these circumstances). I once did a casual test between the FA 31 Ltd, and the FA24-90 and was pleasantly surprised by the 24-90. Certainly saved me a lot of angs...

Lens Comparison - Advice needed
These things are personal decisions, really. Sharpnness is only one aspect of lens performance. I don't think that any 1000px wide picture tells you anything, even a compact can look superb at that size. For example, this is from my Panasonic compact. At 1000px cross, I doubt there's any diffe...

Canon to Pentax converter
I very much doubt it, The Canon mount is significantly larger than the Pentax mount, so any adapter would have to sit proud of the Pentax mount, thus you will lose infinity focus. If you went the other way, Pentax to Canon it would be possible, and there are adapters available to mount Pentax le...

Canon to Pentax converter
No, unfortunately not. You can get adapters that go the other way (Pentax lens > Canon body) but not what you're after. The Canon bayonet is too wide to go in a Pentax mount and the shorter registration distance means you'd have to mount the lens so far back it would foul the mirror in order to a...

Canon to Pentax converter
Yee-ha! I wish to spread the joy. Thanks, Daniel! SRB - http://www.srb-griturn.com/index.asp - 01582 661878 do a Canon (Eos) to Pentax K bayonet converter for £28. This maintains focus at infinity but is manual only - there are no auto functions retained. As an aside, they don't do Nikon to Pe...

Canon to Pentax converter
Do these not contain a glass element though to correct infinity focus ?

Canon to Pentax converter
They will have to have some glass to maintain infinity focus, unless the adapter fits flush into the mount like the Pentax Adapter K.
