Pentax SFXN info reqd
Hello all
I recently picked up the above. Lovely and clean, no marks Bought a Sigma 28 - 70 lens to go with it Thing is the AF doesn't work - not even any LEDs in the viewfinder Could this be the lens is duff? Would the AF LEDs light even with no lens attached? I bought the camera as though I've gone digital I still like to have a 'normal' camera handy The Pentax feels nice and solid and is comfortably heavy! My previous 35mm life was with Olympus so I'm at a loss with what to do with this camera. Is it worth taking to a repair shop or is that going to cost more than it's worth? I could always keep the lens - it's immaculate and I could put it on another Pentax. But I like the design and feel of this SFX so would like to keep it if viable All advice gratefully accepted Cheers Ian -- http://homepage.mac.com/ianmoff iChat/AIM: ianmoff at mac dot com |

Sigma lenses are known to sometimes have compatibility problems, although if it's KA-mount compatible it should work. I'd try a proper Pentax SMC-KA lens on the camera. Also, make sure you've got it switched it to AF mode!! A bit more info about the Sigma lens (model number, etc) would probably help. I could always keep the lens - it's immaculate and I could put it on another Pentax. But I like the design and feel of this SFX so would like to keep it if viable I have an SF7. Very nice and chunky Chris. |

There's the rub - I think I'll have to take it to a dealer Sigma lenses are known to sometimes have compatibility problems, although if it's KA-mount compatible it should work. Sigma 28- 70 UC Zoom 1:2.8-4. No other marks apart from serial number and scales. There is an 'A' next to the f22 mark and a lock button. I guess this is to lock the aperture or set it for auto selecting I've tried all combinations of switching - nothing, although when switched to manual the camera works fine I'd try a proper Pentax SMC-KA lens Off to eBay then Cheers -- http://homepage.mac.com/ianmoff iChat/AIM: ianmoff at mac dot com Ian |

The little 28-70mm f4 FA AL lens is usually very cheap, and optically excellent. Or you could get one of the fine Pentax fast 50s - the F and FA 50mm f1.7 lenses aren't too costly, would give you something different from your Sigma, and are superb lenses. Peter |

Sigma 28- 70 UC Zoom 1:2.8-4. No other marks apart from serial number and scales. Hmm. A trip to Bojidar Dimitrov's invaluable site (http://kmp.bdimitrov.de/, especially http://kmp.bdimitrov.de/technology/index.html#general) is in order; perhaps you can identify the mount visually. In particular, "The other addition to the KAF mount is auto-focus (AF). The only visible sign of the AF capability is a shaft coupling which allows a motor contained inside the camera body to focus a KAF or KAF2 lens." snip -- -Stephen H.

Sorry, my fault. Yes, a KA lens won't autofocus!! Ooops!!! Sorry to the OP - get an FA lens. *runs away Chris. |
