Advice needed on getting lenses for ME Super
Paul, You'll have no problem getting lenses for the ME Super. Yes, it is bayonet (not M42 screw thread - that was for the older cameras). If you are looking for the fitting symbol, you need "PK" (as in Pentax K fit). Note that even though the ME Super is manual focus you can still use the auto...

SMCA 15mm F3.5
I would agree with you - I also use my 20mm (SMC Pentax-M 20mm f4) much more than the 15mm, but there are situations where the 15mm is invaluable. I sometimes need it when taking architectural shots in very confined locations. The 20mm is much more useful in a general sense. I very nearly bought ...

Pentax 28-200mm How good is it?
DayDreamer200, Well, Pentax glass is always very nice. However, I cannot comment on the 28-200mm - maybe someone else has used it. For my Z-1 I do use a Tokina 24-200mm f3.5, which is a hefty beast with 72mm filters, and have to say it is superb. I use Fuji Provia, and scan with a Nikon Coolsc...

FA 50mm f1.4 or f1.7 ?
I have always found that the quality of lenses is really thrown into sharp focus (!) in the black and white darkroom - maybe because we make bigger prints there, even focusing on the grain of the film and so showing up any defects. Up until very recently I have only used prime lenses for b/w work...

Pentax 18-35mm FAJ
I have taken a long time to come to any conclusion. I tried a Sigma 17-35 ... it was soft overall, but particularly at the edges. I tried a Sigma 20mm f/1.8 ... it was VERY soft at the righthand edge only at f/2.8 (in very low ligh conditions, 1/15 sec exposure). By the way, all these lense...

Pentax 18-35mm FAJ
Ironically, autofocus will be happiest when there is enough light and we could happily focus manually anyway! I only use autofocus in portrait sessions where it is fantastic to focus swiftly on the eyes, quickly recompose and shoot. Much more reliable than manual focusing. For everything else...

Pentax 18-35mm FAJ
I have just agreed to buy a used "mint" Pentax A 20mm f/2.8 which should arrive in the next week, or so. I'll post my findings. It is the manual focus version so I will not be in any dilemma about the method of focusing!

Pentax 18-35mm FAJ
The lens I have just bought (s/h Pentax 20mm A f/2.8) works fine with brilliant, crisp images except for two things ... 1. When in "Green" mode it always creates over-exposed images. Setting the camera to minus one stop creates well exposed images every time. This is no real hassel, but should th...

Vignetting
Polarisers don't work very well with wide angle lenses because a large expanse of sky will have varying degrees of polarisation across the field of view and this will show up as variations in colour intensity. The wider you go, the worse it gets. However, with very wide lenses the vignetting in the ...

SMC PENTAX-A 645 ZOOM 4.5 45~85mm with *ist D
I have a Pentax 645 Zoom f4.5 45~85mm lens, left over from when I sold my 645. I would like to know if anyone can help me with information about what sort of functionality and quality I can expect when I use this lens on the new *ist D? Manual focus, ok, I know this, but what about the *ist light me...

SMC PENTAX-A 645 ZOOM 4.5 45~85mm with *ist D
I have the adapter, and 645 lenses. Used it to compare lenses, also 645 ones with M-lenses on a K-x. While I was completely taken by the 645 A 3.5/35mm lens on the K-x, which outperformed the 2/35mm M, 2.8/35mm M, 24-35mm M and DA L 18-55mm by a solar system, the weight is considerable. I doubt I'd...

AAAH...very confused
First, forget the 645 and 67 lenses, which are intended for medium format. The ideal lenses for the *istD will be marked FA-J. These have no aperture rings and are designed specifically for the *ist cameras. In addition, any FA designated lenses will be fully useable and retain autofocus. A...

AAAH...very confused
I'm newly back in the Pentax fold so there is a gap in my knowledge but I don't believe the FAJ lenses were designed expressly for the *ist D, AIUI the 'circle' will cover a full 35mm frame and J lenses (not the 18-35) appeared some time before the *ist D. The first 'digital only' lens has just a...

AAAH...very confused
Malcolm, Yes :) Park rang Tuesday so I whizzed up and snaffled it ;) I don't mind the build so much - it's not as plasticy as the Pentax 28-70/f4 I had on my MZ5. But the build is not as nice as the SMC-F primes, IMHO. However, it's got a very positive feel to it, and it's nice and light. Onl...

Lens review/comparison website
I have found this useful: http://stans-photography.info/ I have mainly been shooting digital for the last couple of years (with a Fuji), and using my Z1-P with a Sigma zoom when I do shoot film (usually slides). Yesterday I got some prints back from the local processor. My wife (no photograp...

Mirror Lens for *ist 35mm camera
I posted on this subject under the "Pentax SLR Cameras" forum. I have had difficulty with my *ist when using my Centon 500mm fixed aperture, manual lens. The *ist is unable to work out the aperture, and therefore the metering doesn't work. :( Fortunately I also have an MZ6, which has almost the sam...

Pentax AF/MF compatability?
Two questions on using Pentax K (no electrical contacts) with modern Pentax AF cameras: 1: Can the camera work in auto exposure if the lens does not have electric contents (at least in shutter priority if not apature prioriy)? 2: Does the autofocus system give any "in focus" signal for the sel...

Pentax AF/MF compatability?
If there are no electrical contacts, as with SMC Pentax and SMC Pentax-M lenses, you can use the lens for manual exposure or for aperture priority auto exposure (you set the aperture, the camera sets the shutter speed) If you use a manual focusing lens and set the camera on autofocus there is a f...

F 24-50mm f4.0 (auto focus)
Optically, this appears to be the same as the"A" version, which is reviewed on Stan's sitee: http://stans-photography.info/ When you find the entry, you will see just a brief sentence saying the lens is a little soft, but click on the URL above and you will get a lot more detail.
