How long will your battery last.
Just to clarify in the case of of the Pentax battery I am fairly certain terminal "T" is a thermistor temperature feedback terminal. Yes, based on a number of articles I've found this appears to be so. I took the Hahnel battery off charge this morning (OE Pentax Charger) and the terminal voltage...

How long will your battery last.
Battery consumption isn't proportional to the number of shots obviously so it's not a definitive benchmark. Clearly not... but what really staggered me was the factor of ten difference compared with my usual experience. ... the amount of AF, live view, and how long the camera is on makes a bigger...

How long will your battery last.
I have started to take lots of pictures at 7fps and noticed a big improvement in battery life. Also just bought a genuine D-BG4 grip. First one was from fleebay and had plastic pins instead of metal as specified in the picture so sent back. Second one was a genuine one second hand but did not have ...

K5 vs M4/3
Hi, I have a Pentax K5 which I love, but I keep getting tempted by the small size and super fast focus of some M4/3s cameras - especially the Olympus EP-3 and the Panasonic GX1. Does anyone own either of these cameras as well as a K5? It would be great if you do if you could share your experience...

K5 vs M4/3
Thank you for your reply. I have played with an Olympus EP-3, and the touch screen focus and shoot was virtually instantaneous. My worry is that I would miss the high iso and DR of the K5.

K5 vs M4/3
I've never seen much point in comparing systems. They are all good and capable of producing top pictures. The only way to see if a system suits you is to try it. In the film days I had Pentax, Olympus, Canon, Bronica and Koni-Omega sytems plus Sinar 5x4..... I would happily use any of them again. Th...

There is a sister site to this one - ePHOTOzine - where there are all sorts of comparisons between marques and where the forum is open to the whole range, rather than being a specialist site like Pentax User. John, I did actually go to ePHOTOzine a few days back, but it is not that active, so the li...

Who is trying to "boost Pentax"? Me? I would say, clearly yes. You, of all people, John, have the most unrealistically pro-Pentax demeanour I've ever seen or heard. To hear you write about Pentax, it is perfect. If it has flaws, we should be figuring out ways of working around them, rather t...

K5 vs M4/3
Very interesting, everyone (didn't know I was stirring up such a hornet's nest!). However, I would still really appreciate it if anyone does have experience with the different formats. My only real issue with the K5 is inconsistent focus, and the appeal of the M4/3 system for me would be the dead ...

Our K-5s just snap into focus with no problem at all, even in the dullest light. I wonder what lenses you are using John, and whether the problem lies with the lenses?

K5 vs M4/3
I have used the 18-55 and 35mm f2.4 My problem has been inconsistent focusing at different distances. For example, the 35mm needed fine focus adjustment for back focus at close distances, but this would then cause the focus to be out at longer distances. I could not get either lens to focus dead o...

K5 vs M4/3
The K-5 doesn't use contrast detection AF in its normal mode (it will in LiveView) so I don't think that can be Chris's inference. CSCs do use contrast detection AF, so , like the K-01, will focus slower. Thanks jhnpennington, it seems you aren't discussing AF speed, but something else entirely -...

Hi, firstly if I could take John Riley's point about the CSC cameras being slower because they use contrast autofocus - in my experience when I have played with the latest CSC cameras the opposite is true. Secondly, I have done the tests as people have suggested. I when through the process of focu...

I have been having a good search through the forum, and it seems like this is not an unusual problem. I had been carrying the test out indoors whilst it was raining outside, so not the greatest lighting. I have come across a few posts mentioning inacurate AF in poor lighting conditions, but the fo...

You need to make your adjustments in daylight, after which any really extreme conditions can be sorted in a number of ways. QuickShift and Manual focus are two alternatives in odd conditions. When I say odd conditions though, they will have to be pretty extreme. Once it gets too dark for the AF t...

K5 vs M4/3
Once it gets too dark for the AF to work properly it's really too dark to manually focus properly as well. Not true. I can manually focus when the K-5's AF is no longer capable. Caveats about Viewfindes not resolving DOFs shallower than F/1.0 still applying of course
