Serious guidance required, please.
I have never found Pentax AF to be particularly slow. It snaps into focus virtually instantaneously, depending on lens of course. It tends to be tracking AF that people complain about, but to be honest I only ever use centre point AF. To put this in perspective someone handed me a Nikon DSLR with...

This is for Gedski...I'm going to get a ton of hate mail for this but I have to say that I have had a love hate relationship with my K-r. I find the Auto focus has a mind of it's own and then that varies again with every lens I have. You can adjust for front and rear focus but it has to be done afre...

2. Am I correct in assuming that CDAF is Contrast detect auto focus and is used only in doing videos and PDAF is Phase detect auto focus and is used only in 'still' photography? not quite correct :) Phase detect AF can only be used when the Mirror is down so cannot be used for video. Contrast ...

Serious guidance required, please.
On the K7 (and K5 I guess as well) you can choose to use either Phase or Contrast Detect AF during Live View operation. If using Phase then the mirror flips down quickly and up again, briefly interrupting the Live View. It is faster and more accurate (as Smeggy just said above Contrast is the slower...

Advice please on K-500 orientation sensor
I am comparing the exif tag in my Canon SX10IS with that of my K-500. The Canon correctly shows top,left for a landscape image when downloaded and in camera it displays correctly, with portrait it show left bottom and again in camera it displays correctly as a portrait mode and on the PC. The K-5...

Advice please on K-500 orientation sensor
Now when I display a portrait image in camera and hit the down arrow button on the back it displays 4 thumbnail images of the possible rotations, I can select the correct orientation for the image and it saves the correct data in the exif tag, it then displays the image in camera as portrait and whe...

K-3 specs leaked?
Got to thinking about super resolution and how Ricoh would get around any Hassy patents for it, then realised they wouldn't have to! Remember this? From the Ricoh RDC-7 way back in 2000: http://www.imaging-resource.com/PRODS/RDC7/RD7A6.HTM One of the RDC-7's most interesting features ...

K5 auto-focus
I have this week added a second K5 body in favour of my K7, and I have noticed a definite difference in the auto-focus between the two K5 bodies. The new body bought this week from SRS has the older 1.01 firmware on it compared to the old one which has 1.14; however the new bodies AF is like ligh...

K5 auto-focus
Try updating it to 1.14 and then comparing. :)

K5 auto-focus
On mine it's not the speed that's poor, it's more the inconsistency of focus and hesitancy, particularly on the DA 17-70. I don't think the speed should be any less on a camera that's done 11,000 clicks compared to a new one. Maybe Pentax have attempted to compensate for known focussing issues v...

K5 auto-focus
I think I will try a couple of other lenses first as is, then see if things feel the same. I will then update the firmware and see what difference there may be.

Time for upgrade body?
Hello I currently use a Km, sparsely, as its not my main hobby. However since having the 35mm plastic fantastic lens I now always seem to find the standard kit dal lens a little disappointing in all but the 50-100mm range of the 50-200. So been thinking of the 18-135mm alongside my 35mm as my ma...

Exposure issues with older manual lenses
The page in question looks as though it was written a long time ago, when the first FAJ lenses appeared. This was the prelude to the digital age as the lenses came out with the new *ist film camera. I think most current and certainly new users won't really care that they have to set lenses to "A"...

Exposure issues with older manual lenses
So which camera bodies did you use? The implication of what you are saying suggests that you might have been using manual focus bodies? Broadly speaking, I think the mount "crippling" as it's referred to came with the AF bodies.

Exposure issues with older manual lenses
So which camera bodies did you use? If this question is addressed to me, then the answer is Pentax ME Super and Ricoh KR 10 Super for a long time. I still have a Ricoh XR-X and KR 10 Super, and a Pentax P30N (2 more film SLRs than I need, but this was a result of a process of rationalisation via eBa...

Exposure issues with older manual lenses
I meter manually more often then not. the only time I ever had an exposure problem, was over exposure caused by an old lens that had the aperture blades leak lubricant and get sticky. so my advice is use a handheld meter; or get a newer lens and take a meter reading, then swap back to the older l...

Exposure issues with older manual lenses
IIRC the instruction manuals state that the evaluative metering doesn't work with pre-A lenses and centre-weighted is used instead (spot still works). This goes back to the Z-1 (the first Pentax to have evaluative metering). This could be one reason why metering with pre-A lenses is different. I hav...

Views from PU's who have upgraded from K5 to K5IIS - Please :)
I can give you a view from someone who hasn't upgraded. I've been torn between either a) getting another K5 b) getting a K30 for focus peaking c) getting a K5II variant d) sitting on my hands and waiting for whats next. Stuck with d) at the moment. I'd have gone for a K5II (probably the ...
