What size for raw please?
I wouldn't bother with anything less than 32gb as prices are very low at present. I just got a MyMemory own brand Class 10, 32gb SDHC for £13.97 inc del. If you want a genuine SanDisk 32gb Class 10 its only £16.97. I've used their own make cards for many years and never had a problem. Service is q...

No it's not. RAW is the unprocessed data that an image is made from, the software you choose to use takes that data and adapts it as you tell it to, then you choose to 'save as' the image type that you want to use. A RAW file is still an image file. i.e a series of binary numbers that denote an imag...

What size for raw please?
Anyway pointless arguing to and fro over this.... back to the OPs discussion. :) I have the last word... Re Gartmores suggestion, perhaps shoot RAW+jpg for a while and see how you get on, if you're finding RAW too much hassle or not getting the results you want then at least you know and have n...

What size for raw please?
I'd caution on that approach - converting in camera results in an 8bit image only - both TIFF & JPEG, and there's nothing between them. You've lost all the 16bit advantage straight away. Sky textures are a bit rough and patchy even on TIFF (just like a JPEG with no NR) and you can't get it back. To ...

What size for raw please?
Going back to the original question ... You can use any card size I would suggest 4 or 8 GB. If you shoot RAW+JPG then the PEF files will be around 20MB each and full resolution, high quality, low compression JPGs around 10-12MB. So, allowing for 33MB per image pair you can store around 30 i...

The predjudice isn't against RAW shooting, it's against people being made to feel they have to because they're doing something inferior. The "serious photographers shoot RAW" is clearly not true, but more importantly leads some to areas that detract from their enjoyment. They don't need it, but are ...

What size for raw please?
I have come to this posting quite late but to answer the ORIGINAL question I prefer to use 8GB cards most of the time even though I always save BOTH RAW and JPEG files, and have found this size plenty big enough. My thinking is that the smaller the card the fewer images you will lose if a) you lo...

Focal Lengths ...
With the front/back focusing issues I am having lately yards would be more than accurate enough :roll: Jim.

With the front/back focusing issues I am having lately yards would be more than accurate enough :roll: Jim. Focal length, not focus distance! It would be useful though to have the focus distance in the EXIF data rather than a meaningless "name".

Focal Lengths ...
I remember many of my old Leica lenses had the real focal length scratched on the back or when the lens head was taken of the 90 and 135mm Elmars with pencil written on the inside of the focusing mount. For example with the 90mm lenses, I had anything from 87- 92 and with the 135mm lenses from ...

Auto Focus Stacking
I think it would be nice if Pentax could use the micro focus adjustment for focus bracketing. It would make focus stacking a lot easier. Maybe it could be implemented in a firmware update. It could be another "first" for Pentax.

They could also automate micro focus adjustment and make it variable across a zoom's focal range, but no, they haven't.

SR doesn't work in the Z-axis. Surely any focus bracketing would be done by offsetting the AF motor anyway?

SR doesn't work in the Z-axis. Surely any focus bracketing would be done by offsetting the AF motor anyway? We were talking about using the lens micro focus adjust facility for stacking automation rather, nothing to do with SR. As you say, at the end of the day, whatever the controlling logic is,...
