Pentax D FA 24-70mm questions
This has probably been asked to death already but ...! I've just reserved the Pentax D FA 24-70mm in Wex Photo pending a reply on their part ex prices. I have the D FA 28-105mm WR and also the Sigma EX DG 24-70mm but wanted to combine the two lenses so I have a wide standard zoom that is WR and m...

Pentax D FA 24-70mm questions
I had the final version of the Sigma (HSM not screwdrive) and it was a great lens but I found a Pentax version at a very good price so bought it. Having had previous versions of the Sigma I found the final one to be the best of the bunch, HSM is faster and quieter than screw drive and it was definat...

Thoughts on PLM lens for tracking with a K-3?
I have this combination (ignore the dated signature), although I don`t have any experience with shooting fast moving subjects with them. This set was shot with this combo Whilst not fast moving subjects, I was separated from the goats by a stone wall with a wire fence topped with all sorts o...

Poss loose connection? DIY fix?
The Sigma 24-70mm has decided when in portrait composition to start saying F- on screen and then if it takes an image it's then overexposed. Flip the camera back into landscape orientation and it goes away! Seems to be when the camera is held upright. Tried other lenses and no dramas so I think ...

Poss loose connection? DIY fix?
Update Was out last night with it and in portrait mode my issues reappeared. Got it home and checked the 3 screws and all were super tight. It does seem to have a millimeter of play on the body when when I looked this play with in the aperture ring so when the aperture is locked into A, I can wiggl...

Poss loose connection? DIY fix?
looking at Sigma service tarrif it would be around £110 for repair Gareth. had my 17-70 done by them for £95, it is in a lower price band than your 24-70 f2.8. it had the image stabiliser replaced and came back looking like new. was away 3 wweeks .

Poss loose connection? DIY fix?
So I called Sigma today and spoke with the service department. They think the A pin over time can get worn and this gives the F- error on screen. When I enquired about a price to repair he said they don't repair these lenses anymore and to go to an independent repairer and also they don't even have ...

Pentax F* or Pentax FA* 300mm
It's personal preference really because as HarisF1 says, optically they are the same. I currently have the F* and use it without the tripod mount simply because I've never found the need to use it on a tripod - the SR system and sensible use of exposure settings are usually more than adequate. Yo...

Pentax F* or Pentax FA* 300mm
I'm yet another satisfied DA*300 user whose SDM motor hasn't failed. If it does fail, there's always the option of converting it to screw drive (which is what I would probably do). It must be possible because someone on this forum (carmagw) reported back in January this year that they had done the c...

Sigma 300 f2.8 thoughts
To give some context, I've found one at a very good price, in excellent condition. Its turned up today so will hopefully see if its a keeper over this next week. If you refer to the new TC, it’s DA and not FF. Someone correct me if I am wrong.../quote] Good point, if I were to use it with ...

Sigma 300 f2.8 thoughts
I have always wanted to try the Sigma 300mm f/2.8, I imagine it should be a very good lens. It has the same screwdrive focus as my 100-300mm f/4 and 180mm f/3.5 and they work well with the Pentax 1.4x although it is a crop teleconverter so you may get dark corners in FF mode.

Pentax DA* 11-18mm Initial user report
A very unscientific user report. I've had my new lens for a few days now and I'm starting to calm down. Sunday afternoon I got out for an hour or so and was able to take a few photos with my new DA* 11-18mm f2.8. Plus I've had a bit of play with it at home. With the limited file size that can be d...

Meike 12mm f2.8
Sorry to hear about the set back and hope you are on the mend. I have a Fuji full spectrum converted, so need the lens to take filters, which I don't think the 7artisan does

For me it is the 50mm f1.7. On both the istd and K70 this seems to give the best results. Probably best on istd as can be a little too sharp on the K70. Paul Are you talking of the 1.7 50mm lenses the old manual focus lens?

Like Chris I find the 150 f/2.8 to be very good on medium format (6x7). Despite having a some lenses of the classic portrait focal length, each time I go back to using the Pentax-M 50 f/1.7 I get pleasing results from this cheap, widely available lens, whether on digital or film. It is also easy ...

Just a thought do members ever consider using the old film lenses for this type of work. I heard on a photographic site. Some photographers were reverting back to these old film lenses in favor of the modern ones. As they felt some modern lenses were giving to sharp an image. Ian
