AF Adapter

1. yes 2. Ebay is your best bet 3. Around £180/200. I dont have one but I believe you have to get the lens somewhere near focus before the TC will do its stuff.

AF Adapter

I don't have one either but if the price wasn't so high I would buy one! They are supposed to be very good. You set the manual lens focus to infinity and off you go. There is a guy on ebay in china selling 7 "new" as in mint, unused, boxed, unsold stock foom Japan at £230 each. Tempting, as used ...

sRGB or AdobeRGB?

I've been shooting in AdobeRGB as i'm a graphic designer who uses a Mac with everything Adobe set up on it. Is there anything to be gained from using sRGB that i'm missing out on? I read somewhere that AdobeRGB images are a wee bit lighter, but don't know if i'll gain anything from swapping back.

Extra lenses for K10D

Pentax 12-24mm or Sigma 10-20mm. These get a lot in the frame and create dramatic perspective effects when you are close to the subject. You're bound to love one of these. The 16-45 is nice, but wouldn't provide much hugely different to what you have already. A 50mm would be good as well for p...

Extra lenses for K10D

For what it's worth I bought a bunch of A primes and barely used them. I'm not sure why I guess I'm just lazy about auto focus and my older eyes just aren't so great at detecting focus. I sold them and haven't missed them at all. That said I do like using my 35 FA and I hope I'll enjoy the 70 Ltd...

Sigma 120-400mm

You could still use the lens. But it would be Manual Focus only. The HSM focussing system will not work with a K100D, it would with the super. Pentax SDM lenses would work using screw drive from Camera, but the K100D couldn't utilise the sonic drive motor. However the sigma doesn't even allow ...

Sigma 120-400mm

I have a K100D (not the Super ). Sigma advise that to use a 120mm-400mm on my camera I need ver 1.03 firmware update. Can only find this reference for an IST DL update , is this correct or can someone provide the correct link. Doesn't seem to be any updates since 2006 for the K100D. As far as i ...

Sigma 120-400mm

Thanks for the responses , can We assume then that the K200D will work with these Sigma lenses ? Marvellous isn't that you can go and purchase cameras manufactured by the opposition and use lenses straight out of the box. Its all very well Pentax having a reputation for their cameras being bac...

Sigma 120-400mm

One for Microlight, If you want a longer lens for your K100 that will work on AF try a Sigma 400mm f5.6 prime lens, the APO version is very rare, but does come up for sale but commands a high price I have got one of the 400mm Auto Focus ones. I am also thinking of selling it, I maybe open to Good...

Sigma Ring flash compatability

Personally as its sold as being P-TTL compatible and Sigma say it works with K20D (see ) but its does not work correctly with the top P-TTL cameras I would want either Sigma or SRS to change it for one that works properly. I think the one you have is simply not fit for purpose. Good luck Bob C...

Does Pentax listen?

About two years back I mad ea post on this site in which I 'asked' for a different type of pentax,...on with a square sensor. The spec that I wanted was briefly, a sensor 23x23mm with jpegs from either horiz. or vert. images chosen by thumb switch and RAW from the full square sensor. This would ...

Does Pentax listen?

having a square sensor and an optional 16x9 (or other standard crops) live wireframe (in live view) mode that allows you to use the rocker switch on the back of the camera to set "Crop" box that the software would use on processing the raw files would be nice. then you move the red box to the area ...

Why would you NOT by a Pentax K200D

I own one and cannot think why I would not buy one. It replaced a Nikon D40 which was dreadful for dust. I believe dust may be present on many D40's but the owners are unaware as they do not shoot small apertures,it is only clearly seen past f16. Mine went to Nikon three times before they gave up ...

K3D* rumour with 1.3x crop factor

Well I don't know about generations, but proper pentaprism finders are very superior to EVFs. You can't judge manual focus on an EVF and the slow response time means that following action is almost impossible. If you want to see a really good viewfinder have a look through a Voigtlander Bessamati...

K3D* rumour with 1.3x crop factor

I'm afraid I simply don't believe that an EVF will equal an optical viewfinder (even a Pentamirror one) in the foreseeable future. The pixels are going to need to get a couple of orders of magnitude smaller and the refresh times a couple of orders faster, all this while making the image brighter....

Using older Pentax lenses

I've just bought a K20D, and I'd appreciate advice on using older (non-A) lenses with it. I've got quite a collection, back to screw-mount lenses (Rodenstock, Angenieux), and I'm reluctant to give them up.

New Sensor?

I have a sensor cleaning pen that is usually very good at getting crud off the sensor (although only a cheap solution) but it will not budge this in the slightest which leads me to the idea it is a scratch. Will leave it until I get back to the UK in March and then do some investigating, I have e...

New Sensor?

Well that was quick, I am to send the camera to Pentax who will take a look and email me a price for repair. If I do not agree then they ship the camera back at no charge to me which seems pretty good. They seemed to ignore my other question as to whether there is a new model coming out in the n...
