Thanks for the replies and links correcting my assumptions. I stand corrected on my worst fears (much less than 1/2 area and circuitry is lost to AF). Seems a less naive time and space division...

Theoretically not quite the same wrt. S/N ratio, considering http://optical-technologies.info/noise-in-photodetectors/

Is actually half of the sensor's effective (light gathering) real estate given away to AF...? Does anybody here know the details on 70D sensor's pixels, ulens design and the readout circuitry? Also...

Thanks for the work and link, i'll give it a try. Thus far none of the leading commercial defishers have satisfied me wrt. crop and distortion types. Actually, i most often prefer the native...

On. This actually is the target, not to switch glasses on/off 2000 times a day (i shoot that much in a good location)... and not to perform 2x that many +/- accommodations (end up shedding lots of...

As a long-time bespectacled (myopic) photog, i found OVF as the best - even when just small, dark rangefinder tunnels as in P&S. Ditto for my wife, who needs reading correction.  However, as...

Love them or hate them, wind and solar are a must... though barely complementing today's oil, natural gas and nuclear.  Blot: Not always, see...

Useful, well written tutorial on an important tool (PS & LR5)... thank you, Jean!
As a previous PS user, i'm still amazed how time consuming even the most basic operations are in Adobe products:...

Besides speed, Picasa has one of the best photo rendering engines around.
Comparing its JPG and NEX/NX RAW renditions vs. LR5 on AdobeRGB displays (lab references 4-9Mpix), i wonder how could...

Good compositions, sharp shots, classy PPS... Superb!

my 3C does the same every now and then, seems random... If it's dead sensel remap, then it's indeed a random process, not just monthly as suggested here. I wouldn't worry about it, though i'm...

it's fairly priced, though i personally prefer the 20-50kit on this NX; the body has a great UI, good (albeit low res) AMOLED, can be customized more than many entry-level dSLRs and NEX... and its...

"the lens does not resolve far-away detail to the point of being tack-sharp at any distance or aperture setting" With the exception of the review samples, hand-picked and calibrated, most of these...

"Ok Did some ruler tests. The infinity is not as sharp as the closer object. This is at any distance on the focus ring. What could be the issue?" Seems that your lens is a bit too far from the...

RNDMAN: The angular operation range (120deg. twist) translates into ca. 1mm of linear lens displacement. Linear operational range (OR): The lens linear travel of an 8mm Samyang across the full...

link seems OK https://picasaweb.google.com/107634715157732050217/Samyang8mmFisheyeOnNEXAndNX100?authuser=0&feat=directlink We're talking about "de-calibrated" as in not able to resolve more details...

Mike, indeed it's interesting to follow the debate, though i disagree w/ the "hyperfocal' (HF) conjecture trying to rescue those lenses not too de-calibrated. Mine, however, was so deadly out of...

Jerry, Chimere: Thanks for the discussion and sorry for x-posting. However, despite its huge hyperfocal range, a potentially large fraction of the 8mm Samyang production is hopelessly out of focus....

Please compare the first 13 shots (before) w/ the rest (after) below. This sample could not focus at less than 10 feet before, at any aperture, on any body (Nikon, Samsung, NEX). No problem...
