John_Y: I posted this at a lower level (in response to another comment. Thought it might be useful to others):

If one wants to be a purists, RAW truly does not exist If one defines it by "Throwing data away". The act of using an A/D converter to digitize an analog signal " Throws data away". Anyway the Sony RAW process is a result of engineering decisions and trade offs which all manufactures do. It is "unfortunate" that we have the technology and tools search look at and magnify . Based on the amount of technology and efforts Sony has shown since the acquisition of Minolita they are probably working on these corner case observations. Probably not a firmware fix but down in ASIC design/ code.

If your work is impacted by the results of this design, then you probably do not want this as your tool.

Any sampled system is just that. You cannot capture it all (nor do you need too). As far as throwing away information... if redundant that's ok. One must still sample fast enough to preserve the highest "frequency component". You are correct...moot as far as topic...however I wonder what really is going on under the hood.

stevevelvia50: Perhaps this can be corrected with a firmware update? I wouldn't think it would be very problematic for 98% of images made with the camera, and even when it shows in a small percentage if photos, it wouldn't be that noticable. That being said, the highest quaity of RAW file should be accessible, especially at the high price being demanded for this camera. I just don't understand why Sony would make shch a marketing errror.

On article A look inside Sigma's lens factory (89 comments in total)

I come away with the feeling of focus and precision. All business. Seems cold, dark, and impersonal, however I an "more trusting" of product out of that factory after the video. Can't put my finger on it.

I purchased CS5 and it has served me well. I was (am) in the middle of "migrating" to CS6 (in trial). It seems that I can not purchase CS6 stand alone now during the trial period. All that can be purchased is the CC subscription. This is my hobby and I don't want another "monthly" bill. Can anyone confirm if the $199 upgrade is available (it was yesterday!). That is CS5 extended to CS6 Photoshop.

Does anyone know what "other improvements and bugs fixes " means...or is that a generic statement. I do not have the 16-50 lens and if there is no need to "wipeout" current settings (does firmware update do that?) then I won't update. Any suggestions.

On article Photo Tip: Five for Five (111 comments in total)

Thanks for the article...This is very simple technique and as they say less is more. You have detailed a technique that will alow myself and others to "capture" a keeper. I constantly remind myself to slow down because often I get cought up in the excitement of the moment.
