M8.2 and the 50mm Summicron APO

1) The M8 has the same resolution as the M9, it's just cropped. The M8 images are "more crisp" to my eyes as the IR cut filter over the CCD is thinner than the M9.

2) For Black and White conversions, not need to use an IR cut filter over the APO- their will be no "IR ghost image" as the lens is better color corrected.

3) for color images- use an IR cut filter to get true color rendition.

4) Use Arvid's M8RAW. DNG-8 compression kills the fine detail of an image. Shooting Raw preserves more detail. If you are spending 50APO money, you are paying a premium for details.

 

I've used a Pentax Ultra-Achromatic 85/4.5 on a 12MPixel camera. The color rendition is beautiful.

Certainly a desirable lens to own (possibly more so than to use) and better to buy it second hand and let someone else take the initial depreciation hit. I don't think it makes any difference what camera body you plan to use – the lens will be useful long after the body has ceased to work or be relevant.

Couple of snaps at f/2 with M8.2 and current apo & non apo 50/2 (1.20m, C1 v4, CS3, 7MB files):

Thanks for showing these 2 images. Indeed a very significant difference!

It seems to me no. 2 is slightly out of focus. The edges of the text "Atmos" (marvelous piece of timekeeping btw :p ) in no.2 is more pixels/lines wide than in no. 1... This way no. 1 gives a greater feel of contrast and sharpness...:rolleyes:

Copy of another post (sorry):

Calibrated RF and 6-bit lenses (50/2 # 4156***, 50/2 apo # 4296***), tripod, cable release, focus bracketting (focus on the "VIII"). I did not keep the raw files but you may wish to take a look at these later snaps with metadata. Hope you can read them as i'm on an old Mac here (C1 v4, CS3). Please feel free to crop or reduce the files if need be
