As greynolds999 states, you current PC looks OK, however you may benefit from a graphics card upgrade.

A better reason to upgrade would be SATA 600 (if you want to use solid state hard drives), USB3 for external hard drives and support for DDR3 memory.

One point to note, most programs are written to use one core, some can take advantage of 2 cores, very few (i.e. games) can use 3 cores. I do not believe that any programme will currently take advantage of 4 or more cores. The OS will however distribute processes across the cores so great for multi-tasking.

If you want to speed up a PC, invest in a good solid state harddrive! It's what Windows 7 really wants!

I really want to know more about the video capabilities, such as focus during video, internal microphone noise and the various resolutions/frame rates avaliable. Also how is the video white balance and apature/gain (ISO) control handled?

The K7 has 77 seals and 77 segment metering - it was a part of the marketing, all the 7's. The K5 is an upgrade!

I will do a search for the Polaroid one and are what it looks like, thanks.

Pall, looks interesting but seems to not connect to the camera, but provide a recording track that will need to be overlaid on the video track. Or have I missed something?

I am looking to upgrade my current microphone for video. It is a basic but does the job quite well, however the wire is damaged from storing in my camera bag, also when I use the camera through the viewfinder when the mic is attached (as I like to switch from Video to stills) it dents my head and is in the way.

Does anyone have any experiance with a good medium range sterio michrophone that is hotshoe mounted at about £100 price mark? It needs to be reasonably compact, and not extend too far back so that the OVF can still be used.

Was at the London Wetland Centre on Saturday afternoon and I saw 2 other Pentax owners, even spoke to one! There were a couple of canons and a nickon user or two, however the balance was very good - then it was raining!

Not all the EXIF data is avaluable, however, just the focal length as a searchable range could be very useful.

I sometimes search the gallery for shots by subject, however when considering new lenses, it occurred to me that searching the Gallery for images taken at a certain focal length or with a certain lens might be very useful.

Anybody else think so?

As this information is in the EXIF data, it should be possible.

Larger buffer size, faster processing chips, faster data transfer rate to faster cards

Even if the if the rate at which the buffer can be cleared off to the card is the same, at 62.5% bigger image files the frame rate should be 2.19 (using a very basic calculation)!
