Pentax warning on rechargeable CRV3's
(Back from hols :) ) There are two types of rechargeable CR-V3s. There's the original that are to be avoided - they have an output of 3.6V, and this is too much indeed. Then there's the Uniross "compatible" CR-V3s which have three terminals and output at 3V and claim "100% compati...

Pentax warning on rechargeable CRV3's
I do worry about those Uniross CRV3s. I have two pairs which I have been running on my DS but I have found that newly charged they seem to have an on-load voltage of around 3.4 volts so I worry that a pair at 6.8V is a bit risky. [Measuring on the 3rd terminal, which I assume is before the diode...

Pentax warning on rechargeable CRV3's
Having fully discharged and recharged my 4 NiMH's (see previous post), they seem back to normal - whereas they were showing 'half' power after 70 images or so, I took around 400 on saturday and they still showed 'full'. Maybe not the most scientific way of doing things, but it worked for me. :D ...

Pentax warning on rechargeable CRV3's
Just had a couple of weeks away (sunny Cornwall), and started having problems with my AA's again. After a few dozen shots, they'd show half power. "Blast", I'd say (I think that was the word :wink: ), and try switching off, then back on, and usually they'd show as full. I use a 'D'...

Where are they made?
I wonder if there will come a time when further development of digital sensor technology will be unnecessary and we will again see camera production runs lasting years, rather than months. Pentax's range of digital cameras are very good, but I can't imagine them ever being held in the same regard as...

What, hovering like this? :D istD, Sigma 105mm f/2.8 @ f/13, Manual Focus (preset then waived in front of hovering hoverfly), manual flash - Centon FG30 with diffuser. Cropped down to approx 1/4 of the frame. This one worked, many didn't! :D But nowhere near as sharp as Brian's. ...

Great Shots. Hehe!! macro is fun when you have nice bugs around, gonna try and set a focus trap this weekend, see if I can match Dan's excellent shot. Peter, that bug would feed my cat for a week, pity Scotland is so cold and damp, bugs that size never come this far north.

Hi Brian, That shot was taken by focusing the lens to about 12 inches, holding the camera at arms length, looking out for a hovering hoverfly and approaching as quickly as possible, then guessing when the hoverfly was in focus and taking the shot. Just so you can see the results you can get wi...

I think I was lucky - only about 40. There was one more than was nearly as sharp. But it was a pleasant afternoon spent in a Welsh cottage garden when we were on holiday back in June, so I didn't mind one bit, I could happily have taken 100. I wouldn't call it a perfect one either, by any means...

Quite right Peter, wouldn't have even tried. That was one of the reasons I convinced myself to 'go' digital - I kept seeing potential images, that may or may not have worked, and thinking "if I had a digital camera...". And I justified the initial expense of the camera, lenses, memory ...

Anybody suggest trap-focus? You set the camera on manual focus, use a manual focus lens or the manual focus ring on your autofocus lens, and set it up so as you track the quarry, when it enters the focus distance you've set the shutter goes off.

Don, that's why I said "I think I was lucky"! I was also lazy, because although the composition was poor, I didn't try too hard to get a better one, thinking it would be easy enough to digitally move the fly if need be: Original Moved Arthur, Brian mentioned this a little f...

ISO Setting Reminder
Hi All, One of the benefits of digital photography is being able to vary the 'film' speed between shots, so the most appropriate speed can be selected for the situation you're currently in - great. However, after several occassions when I've changed the speed to 400 or 800, from my usual and p...

ISO Setting Reminder
There is a very useful button on the back of the *istD and I think the *istDS labelled 'INFO'. Can you tell what it does yet? If your model has this button, try to get into the habit of pressing it before an important shot, or every new shooting situation for that matter, and review the INFO that it...

Shock News!
Hi, just thought I'd say that of the Jessops stores I've visited in the last few days, most had the K110D (the K100D without shake-reduction) selling for £399 with lens, but not the K100D itself. A couple also had the DL2 still selling for £350. Obviously the fact that it's been replaced by a virtua...

ist DS problem! Hope I can fix it :(
I tried loading the newest 2.01 firmware... with bad results. The firmware update app showed "COMPLETE" and i turned off the camera, turned it on... and the menus work just fine, the new features and fixes were showing, etc. Bad thing is, in any mode, none of the features worked what so ...

ist DS problem! Hope I can fix it :(
Stevey500, It would be very foolish to try and 'fix' such a complicated mechanism as a Pentax metering system. Most of the clever bits are inaccesible to Joe Public as they surround the pentaprism/pentamirror. And if you were to open your camera to 'fix' the problem you would certainly 'break'...

ist DS problem! Hope I can fix it :(
that is true, i dont want to do anything obvious to expire my warranty, just looking for a possible easy fix. but yeah i have tried going back to 2.0.. same thing, but if I go back to 1.02 it works just fine in manual mode.
