Kr - AF Fine Adjustment
Film is build up with 3 layers much like a feavon sensor and the grains have some thickness too, no idea about what kind of thickness you're talking about but it's much thicker then digital. Don't get me wrong it's also an issue with film but less so. Just to give you an idea how precise it is, ...

Kr - AF Fine Adjustment
I forgot to say that 1/100 of a millimeter is the difference it makes at the sensor, quite stunning how much impact it can have and how precise everything must be. I've looked the numbers up when talking about medium format digital backs and arguing that the Pentax 645D can be make more precise t...

K7 to K5
It is worth it particularly on the high iso and dynamic range front. But I suppose you have to ask yourself how much these things are limiting your photography at present, and what new body Pentax might bring out next. And then you need to think about the cost. If you tend to shoot on sunny days and...

K7 to K5
I believe the difference from K7 to K5 is far less than K10 to K5, in terms of focus speed. The K5 is a little better than the K7 but I think a little more incremental than the shift you have experienced Matt. My personal concern about upgrading would be that Pentax tend to upgrade the sensor wit...

K7 to K5
In terms of the use of the word "tragic".... When I was a K20D/K10D owner I didn't have a problem with anyone saying the K20D/K10D had an ISO performance tragic in comparison to the K-5. I realised they were right and it encouraged me to sell sell all my wives and grannies in order to get a couple....

Using K100D and older flashguns
If you set the K100D to P and the flash to one of the two Auto modes then it should work as a fully automated program flash, with the aperture being set according to the ISO you pick. You can also use those modes with the camera in M, in this case you set shutter speed, ISO and aperture to what ...

Using K100D and older flashguns
On my K-m it sets it to 1/45 or so, which is ok with SR. To be honest you'd be better off finding the max sync speed and setting the camera to that in manual mode, it'll be faster than 1/30. I know I've used an AF160 before now, just setting the camera to what the flash expects and letting the f...

The Pentax Q is Imminent
Hmmm, I have 3 days left to return my Panasonix LX5. :? The sensor is a lot smaller on the 'Q'. The LX3/5 will be hard to match in terms of IQ. regards chris:D

If you want smaller just buy a point and shoot? For a third of the price and no worries about the sensor getting dirty and so on.

No wide angle lens yet and manual focus ffs.I can see ths is going to fail big time. Will be interesting how long will Ricoh continue to pour money into R&D into this. The only way I see this work is the range of small (read tiny), fast prime to increase quickly, a super massive resolution screen an...

The Pentax Q is Imminent
fast prime to increase quickly, a super massive resolution screen and something miraculous happens in sensor technology. The lowest f-number they can get would be f/0,26 at 9,2mm so there certainly is room for improvement. Technology is always moving forward, so no doubt they will reach a point t...

The Pentax Q is Imminent
The more I think about the Q, the more I have a sneaking suspicion that Pentax know something about a new type of sensor (something Ricoh has in the pipeline?), and want to get the jump on competitors by already having the hardware in place to implement it's introduction. It might not be coincidence...

I agree it is over-priced. I think there is a possibility however that the Q might end up in a later incarnation being an amazing bit of kit. If some radically new sensor is on the horizon then the one-lens-does-all approach of compacts is not going to be able to keep up with the technology. There ...

AS regards the viewfinder, I don't know what it is yet, optical or EVF, but an Olympus virewfinder has stabilised out at £199, not too far adrift from £240 RRP. That one are EVF i believe. Like it or not, we're talking about high class engineering and the cost is going to be high. Indeed, it's am...

I've added some prices of other cameras :wink: Is the Olympus E-P3 + 17mm which sells at £799 not overpriced? :? It's got a Micro Four Thirds sensor. The Q has got the tiny 1/2.3-inch sensor from

The Fujifilm Finepix x100 was about £1k when it first appeared. It's got not only a viewfinder, but an APS-C sensor!! Even better than a micro 4/3rds. The Pentax Q start price of £600 + £240 viewfinder = £840 has a tiny sensor which you would find on a £200 camera from other companies.

But the price that is showed now at the store is the advised priced by Pentax and therefore not the street price. The price when they will hit the shelves will be lower then that for sure, between the 500 to 550 pound most likely. Hopefully by christmas it might actually go under the 500 pound mar...
