Nice little review on the FLU Card
I had Flu about 12 years ago, was not very nice, so will not be paying a 100 squid for a card full of germs:shock:. As for WI-FI/Tethering or Gps, i buy a camera to take pictures i don`t need the techy gismo`s, and that go`es for the dreaded video to. If you need GPS to tell you where you are you ...

Exact crop factor of K3 Sensor.
Anyone know, the exact crop factor of the 23.5mm x 15.6mm sensor in the K3, and no 1.5 won't do!:twisted: I need to know the exact value, my little brain won't wrap itself around that one today.:oops: Got 1.53 in my head but that could be wrong of course... Ta in advance...

Exact crop factor of K3 Sensor.
Is it just the aspect ratio you want or the exact mm size? The aspect ratio is the pixel size of the RAW files. 6016w x 4000h = 3.008:2 or 1.504x The spec. also mentions 16:9 which I presume is a crop. EDIT: If you mean compared to 35mm FF it's 36/23.5 = 1.532 OR 24/15.6 = 1.538 base...

Exact crop factor of K3 Sensor.
I always thought the crop factor was calculated as the diagonal of a 36 X 24mm frame ie 43.2666mm approx divided by the diagonal of the particular sensor you are comparing (APS-C 23.7 X 15.7mm is 28.4285mm approx). If so the answer is :- 1.5264180559885595966299171925376 Hope that's exact enou...

Exact crop factor of K3 Sensor.
Jules, I think they use the diagonal measurement due to a throw back to the original TV Cathode Ray Tube days. As the original tube faces were circular the measurement of screen size was the diagonal of the largest 4:3 aspect rectangle that could be made from the tube face. It doesn't really make a...

It doesn't really make any sense these days but they've stuck with it Bit like the FF debate then :mrgreen:

I'm very curious as to why you like / need to know the exact crop factor :?:

I'm very curious as to why you like / need to know the exact crop factor :?: Indeed, I would have thought that 1.5 is near enough for most purposes. Do tell.

jamieallen gave an answer - but with an incorrect calculation which I corrected. That is assuming the sizes of a 35mm frame at 36x24 and APS-C at 23.7x15.7 are exact and for example an APS-Cis not 23.7003x15.7002 But Jules wrote in his first post that the K-3 sensor is 23.5mm x 15.6mm (as shown ...
