macro lens
any advice on a good lens fo use on a bellows is apreciated. SMC Pentax (M,A,F,FA) 50mm 1:1.7 makes an excellent companion to the bellows for macro photography. I believe the 1:1.4 variant has a flatter field of focus, useful for copying. It's the other way around. The 1.7 is flatter, and therefo...

macro lens
Is there a lot of difference between the bellows lens and a normall lens, greater dof maybe? Thanks pete Two main differences I think. The dedicated bellows lens is 100mm 1:4 and has a flat field of focus and no means of adjusting focus which is achieved by adjusting the bellows. Is the bellows ...

macro lens
It is specifically designed for Macro work. At greater than life size, any normal lens needs to be reversed. Even at 1/3 or 1/2 life size a "normal" lens is not ideal due to the relative angles entering and leaving the lens. The bellows lens is "ideal" in this respect. As has bee...

DA 10-17
I've noticed it's a lens that hasn't been discussed much in these forums. :?: :?: :?: I did a search for 10-17mm and got 45 hits here. Lots of info in those topics and some very good tips on its use. Also try going to http://www.pentaxphotogallery.com/ and from the home page click on Image...

Pentax 18-250 or Tamron 18-250
amilner. Glad you like the Tamron 18-250mm. I have it and believe it's a great lens. Seems to me so many DSLR owners get carried away with a pot full of lenses, some also get a bit snobby when it comes to using big zooms. Fact of the matter is most of the time one can end up with a really g...

Pentax 18-250 or Tamron 18-250
SK and DB. I had the Sony 1000 when it first came out and I can assure you I printed many great images 8X!0 and had them printed much larger and they still looked great. Have used every decent P&S and most bridge camera's with similar results. Although I will probably never go back to it ...

200mmf4 M gets first outing
having discovered the battered old smc M42 200mmf4 I got for nothing was actually very good, I looked out for an M lens and one arrived in the post this morning. This shot is probably out of focus and shaking in the wind :) I'm very impressed with this lens. Nice colour, shallow dof, what is it'...

smxP FA 50mm f/1.4 vs SMC M f/1.4 50mm
There will be no difference in optical quality between the two, apart from any normal variation between samples because of manufacturing tolerances. However, the M version has no electrical contacts on the mount so will have to be used manually in stop-down mode. This is less convenient and the S...

smxP FA 50mm f/1.4 vs SMC M f/1.4 50mm
I notice a difference with built-in flash, external flash, internal meter (exposure accuracy), also. the af version is easier, for those who like the AUTO modes. I use a handhled flashmeter, manual focus/exposure and so either works great for me.

smxP FA 50mm f/1.4 vs SMC M f/1.4 50mm
I suspect this might be due to the metering with a non A lens. I have noticed some difference between various 50 post M but this tends to be across the board and is only noticeable on 16x12 prints. There is a more noticeable difference with the earlier "K" version though. I would go wit...

Sun Lens 39-90mm f3.5 Macro
This is a budget zoom, probably of quite modest performance. The filters: Softon will be soft focus for portraits, etc. FL-W is for "white" fluorescent light, cross is presumably a cross-screen to give cross-shaped flare effects from lights at night and the Polariser will of course dark...

Building your own set of lenses in Pentax World
I thought I'd share my kit, as some people might be building their own (now that Pentax is back in the limelight) and since Christmas is just around the corner. Also, it might give us a chance to discuss how well some lenses work together. It took me quite a while (and money) to get here, and lots o...

Building your own set of lenses in Pentax World
I'm always interested to hear what other folks use as their personal kit as no two people seem to be the same. I own six lenses with my K10D, three of which are languishing lonely and unloved in a drawer; a Pentax DA18-55, a Tamron 70-300 and a Pentax M50/1.4. I'll probably keep all three as the...

I have the KA50 f1.4, bought it as a student and never regretted it. I was also happy to find it performed excellently on the K10D and also allowed me to controll a slave flash by setting the camera on manual and selecting the apature from the ring to controll flash light. A bit hit and miss on th...

SMC 50mm A - 1.7 WOW !!
Check that the focus mode switch on the camera is set to manual - otherwise it will only take a photo when the subject at the focus point is exactly in focus (useful under some circumstances but generally a pain).
