I have only had cameras reapired, never routinely serviced.

The one exception was a very fine Voigtlander Bessamatic that was cosmetically so superb that it deserved a full overhaul and it got one. Now that was superb engineering, very over-engineered in the way that the Germans do best.

I have had one MX repaired, one MV repaired twice and one K10D repaired.

Many thanks for the report, IT will pick that up and look at it.

Your best bet then is to make a report asking for a new tab under Forum called "Unread Posts" and I'm sure if it's possible to do then it will be added to the To Do list.

As far as I can tell the green markers exist until you leave the site. By logging on from elsewhere it was presumably arriving fresh, so to speak, so the only green markers would have been new ones since your last visit.

If that's a problem why not just minimise the page until ready to resume viewing. I can understand that it's daunting to try and read everything if you haven'y visited for a while, but it would be the same if it kept the markers. You would never know what was new, just what you hadn't read.

As things stand, you arrive at the site and everything that's new since your last visit has a green marker. You leave the site and the slate is wiped clean. It seems to me as good a way of doing things as any other way. If the markers remained, then eventually everything in sight would be marked as green unless you read every single post. If you do read every single post then the current system isn't really a problem anyway.

As a rough guideline what speeds would you suggest the SR becomes unnecessary?
The old rule of thumb is to use a shutter speed equal or faster than 1/focal length. E.g. for a 50mm lens use 1/50 s or faster.
The Pentax manuals explain that this figure is modified by the crop factor. So a 50mm lens, for example, with its "35mm equivalent" of 75mm needs 1/75sec or faster.

Of course even this may not be enough unless we take care, so to be sure some photographers double this again to 1/150sec.

As an experiment, try fast shutter speeds on and off a tripod and the critically sharp ones may still be the ones with the tripod.

SR mechanisms are fine when the camera is intended to be held still and the subject is still. They don't help at all with rapidly moving objects, panning, and probably much of sports photography.

Even a simple picture of a flower, which may be moving in the wind, can be an action photograph.

With close ups, limited DOF is the problem, so keeping the camera still with SR is still second best to using a firm tripod. We tend to waver backwards and forwards, so the point of focus shifts very easily when hand held.

There are plenty of forums on the web that I don't like in one way or another but I don't get over excited about it.

All forums are not the same and they don't all operate the same way except PU....

I'm pleased to hear the articles have been useful Andy and I'm hoping that in the fullness of time there will be more. It would be undermining PU a bit if I started to distribute copies through their forum, effectively in competition!

If you don't want to join PU Plus then PU are selling off the magazines at the cost of postage so you might consider getting the appropriate issues?
