smc FA 1:1.4 50mm
Just treated myself to a new lens,smc PENTAX-FA 1:1.4 50mm. Thought from various reviews it would be good for portraits. I've got a K10D and another couple of lenses but I can't figure out how this 50mm works.Can't get it to shoot blurred background at f1.4 on either automatic or manual settings.Man...

smc FA 1:1.4 50mm
I have this lens. the focus ring turns to focus. You cannot pull it in and out. not sure what yo mean by "Can't get it to shoot blurred background at f1.4 on either automatic or manual settings" Do you mean you cannot set it to 1.4 ? Or do you mean when you set it to 1.4 the backgrounds aren...

smc FA 1:1.4 50mm
Probably a silly question but do you have sufficient separation between the subject and the background? The nearer the background to the subject the less the out of focus (bokeh)effect. Sorry if this is self- evident, and not applicable.

smc FA 1:1.4 50mm
Good point. Being relatively new to this not sure what separation distance should be but my attempts are sharp front to back over about 15 yards. It's getting a bit dark now but will experiment tomorrow. Thanks.

Any recommendations for decent 3rd party M42-to-Pentax-K mount adapters?
The Pentax originals are certainly much better quality than the 3rd party versions - many of which do not allow infinity focus I had 2 Pentax originals - sold one last month for £39. If interested - happy to sell my remaining one for the same price - and will throw in an M42 2x tele converter...

Any recommendations for decent 3rd party M42-to-Pentax-K mount adapters?
There are a number of decent quality M42 adapters to be found on eBay from 'name' manufacturers, that fit well and focus to infinity. I purchased a brand new adapter manufactured by Kood and it was around 6.50GBP delivered. I think Hama used to make a pretty decent copy. There are also lots of no...

Any recommendations for decent 3rd party M42-to-Pentax-K mount adapters?
I have four '3rd party' adaptors all permanently fixed to M42 lenses, including a fairly substantial old Tamron 300mm Adaptamatic. If you choose the right seller and fit these properly (remove the spring clip if you need them permanently attached) you will have no issues. Mine cost me around £6.50...

Decent wide angle lens
Personally I don't think you need 10/12mm. I have a Sigma 12-24mm but it very rarely gets used as I always found 16mm on the 16-45mm (and now 17mm on the 17-70mm) more than adequate for landscapes If by landscapes you really do mean "land" (mountains, etc.), then I would agree. But for townscape...

M42 manual zoom
Thanks John, I don't think wildlife are in danger from me using this lens (unless I drop it on a snail or something). I suppose if I find a use for it at a particular focal length it's worth switching the camara off and back on again. regards Bernard

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
Back in 1997 I went to Florida and while I was there I thought it would be a good idea to get a lens. I had decided on a 80-200mm 4.7-5.6 zoom by Pentax. I went to a Pentax dealer and he tried to sell me a Sigma equivalent. I put it on to my camera and it was awful, grit in the works, which he claim...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
By cheap I mean in compirison to "named" brands, and by my experienace as shown above I could say they are "cheap and nasty". Try the Sigma 100-300 f4 and then get back to us. That is definitely not cheap and nasty. Try the Pentax Lens Review Database for the consensus...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
I borrowed one for a wedding not so long ago. Initial impressions were favourable - nice build, lightning quick autofocus (even in low light in the church), good IQ and personally I didn't find it heavy. The OS didn't seem to make a massive difference but then I only had it for a few hours so pro...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
No personal knowledge Peter, but I was looking myself a while back. Concencus seemed to be that the older Sigma APO was a better lens. While I plumped for a 60-250, that aside I had pretty much decided on the Tamron 70-200. Whilst it is notoriously slow in th Nikon mount, it is apparently quite f...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
I'm finding problems with Focusing on this Lens. Using either my K10D or K20D. But when I get it right the results are superb. I have to zoom back to 70mm before the autofucus kicks in correctly. i.e. the green light & sd icon comes on. Any idea what's wrong...apart from me...!!!:lol:...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
I have the non OS version (APO DG EX Macro HSM II). It's superb and I think one of the best buys available . In Perth it costs AUD 700-. It's a favourite with me. Very fast focus lock. I do use it with 1.7 AFTC sometimes. Gives garbage readout for exposure but correctly exposes anyway!I wouldn't hes...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
You won't regret getting the 70-200 it's awesome, especially its AF speed, as you know the K-7 is not exactly lightening on the AF front but with the HSM it's great. I do shoot on continuous focus and hi speed and tend to take a burst of shots as the karts or cars head towards me and tend to get som...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
What lens are you currently using? Mostly DA* 50-135mm & TAv mode on the K5. I tried both the DA* 300mm and Sigma 150-500mm, both were too long and too slow, or maybe I just need more practice. I only use the K20D & DA* 16-50mm for close ups of the drivers and cars when I can also use flash (if ...

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
The K-30 has been shown to have improved SR in tests. An improvement not possible with in lens SR which goes back to the film era.

Sigma 70-200mm F2.8 EX DG OS HSM Lens - Pentax Fit
So how you getting on with the Sigma Peter? I've used it at one race meeting so far with mixed results, but I put that down to me, not the lens. I'm thinking I might need the low light focus abilities of the K5 II or K5 IIs. I haven't been able to use it much in proper daylight yet but I'll...
