Pentax screw lenses on Digital body - Advice Please
The Pentax Adapter K will do the trick. I suggest you set the lens on M, open it up to focus and then close it down to the aperture you want to take the picture. Aperture priority will work fine. The alternative is to set the switch on the lens to A to focus and then switch to M to stop it down,...

Pentax screw lenses on Digital body - Advice Please
Hi itsme, teh adaptor is working fine. It's supposed to stay in the body, AFAIK. This is because, on my adaptor anyway, you have the clip that locks it in place. If you locktite the lens to the adaptor, and the clip isn't released fully with the lens release button, you'll be stuck with that ...

Sigma 50-500 and K10D STRANGE!
Just had a wierd experience with the above combo, I was out shooting birds and had the aperture wide open (f6.3), I was getting a shutter speed of 1/180th (in Av). as I was using a tripod and using the SR I thought I would try a smaller aperture, Now this is the strange bit, I went through f8 and f9...

K10D and Teleconvertors
Insulating tape is a bit of a no-no, as it tends to get gunged-up when attaching and removing lenses. I have tried taking my Kenko PzAF 2x apart and physically removing the data pin (not too tricky) but it didn't work: the camera still managed to read the focal length from the lens. No idea how: per...

K10D and Teleconvertors
Off topic :oops: Haven't been able to test it out on the K10D yet as it's back with Pentax being repaired. Whats wrong with it Stevo? Doesn't sound good that it's already in for repair!

QUESTION ABOUT MACRO LENS
I think optically the Pentax and the Tamron are en par. The Pentax has no focus limiter, which is a concern only if you shoot other things than macro with the lens. The Pentax has Quick-Shift and is the smallest and lightest 100mm lens. The Tamron to the contrary has the limiter, has 9 aper...

Second hand lenses price guide?
McKeowan's Price Guide to Antique and Classic Cameras. HC £100 PB £90. This covers all the manual focus stuff at least. Otherwise, a copy of AP will give you a pretty good idea and a look on eBay will clinch it!

Second hand lenses price guide?
Hi Chris, Really the short answer is NO. These price guides that do exist are well out of date the moment they come to print, let alone some time later. The camera market is now, due to digital, far more fluid than it used to be and far more fluid than the car market, making any lens or camera...

help me please to choose pentax m 300m f4 or 400mm f5.6
There were no bad Pentax lenses in these focal lengths, and they are all pretty rare, so my advice is to buy what you can find. If you hold out for one particular lens, you may never find it. I own the M 400 1:5.6, and I used to own the K 300 1:4. I've no complaints about either, but my present...

Tele zoom for K10
I have no knowledge of the 100-300mm. I havn't used one either but Stan Halpin's site seems to suggest the 80-320 is better. the 80-320 and 50-200 are both very good lenses for the money. The 50-200 has manual focus override, a smoother zoom ring and a non-rotating front element. It is also sm...

Tele zoom for K10
in that case you don't want the FAJ 75-300 either, it has no aperture ring so wont work in any useful fashion with your KM. As I said the 80-320 is very happy on a K1000 so should work wonders on a KM. It's focus ring is rather loose by comparison to MF lenses, but it's useable.

Good Old 80-320
Well folks, today I actually took off my shiny new Bigma and replaced it with my trusty old Pentax 80-320, this is the first time I've used it on the K10D and at first I was a little dissapointed, to be fair I was trying to focus amongst a load of twigs and branches but I eventually gave up and swit...

70 210MM pentax vs vivitar
Hi Chr Welcome to the forum. For use with the K100D it has to be a Pentax DA50-200 ( the Samsung labeled one is the same but cheaper), you will be amazed at the size of this lens, in a word it's small, at the moment nothing else comes close in cost v quality unless you go past the £600 mark an...

70 210MM pentax vs vivitar
I strongly recommend the A70-210 f4 It's manual focus, but it's incredibly sharp even wide open! I used it for years on film bodies, and still use it on digital. It is fantastic to say the least!

70 210MM pentax vs vivitar
On the subject of good manual focus lenses, I own the underrated Tamron SP 70 - 210 f/3.5, which is an excellent performer, if a bit hefty. The 70 - 150 f/3.5 is also pretty good, & much easier to handhold. Coupled with a PKA Adaptall mount these give good results on digital, & are massively...

70 210MM pentax vs vivitar
The Vivitar S1 70-210 (version 1,2 or 3) is a superb lens and I would pit it against Pentax any day. It is big (ish) an heavy because it is made of metal and glass. I originally purchased mine new in the mid eighties, first for a Pentax P30, then a Super A. Using it on a DL2 now - beautiful pic...
