OttoVonChriek: "As it turns out, my little tests just confirm things that were already published (if obscurely.)"
Well they certainly draw one possible conclusion. There are others.
A simple explanation for needing both newer cameras and lenses, is the following:
1) Nowadays PAF sensors are incorporated in large sensors with normal imaging capabilities. This provides additional information for exposure and focus algorithms.
2) Mirrorless cameras have shown how lenses need a continuous servo mechanism for high speed CAF foccusing.
3) A hybrid system would send a lens hurtling towards the position the AF sensor indicates, but continue to improve the lock using CAF data.
4) Canon have just entered into the mirrorless market and (Kudos to them) have chosen to use their standard lens mount rather than a new one. Therefore new lenses will be expected to incorporate the continuous servos essential for CAF.
I'm not sure how new all this is.Remember the ultra fast super precise E3 + 12-120mm?
"Canon have chosen to use their standard lens mount rather than a new one."really?
MDwebpro: Fun shot, but not uniquely creative or difficult to light, and certainly not worthy of a challenge win (as is the case with a lot of the winning photos on this blog).
I mean no offense to you, and I'm not trying to rain on anyone's parade, but I did work more creative than this in the Tabletop Photography class I had in college, 20 years ago.
we all eagerly wait for your "worthy", "more creative" contributions to the challenges, mr. webpro :D
stanic042: based on photozone review, this lens has bad reputation among some pentaxians, but this could be to sample variationI like the results
looking at the samples of Canon 18-135..okay, sharp enough, but there is also massive CA in the corners (even @ f/11) that requires correction, after which this sharpness will be lower

win39: They look to me like a big ego taking revenge against a client who has already deposited the money. "I am so good, they will think they are art and I will be laughing. Ef the Olympics." Hopefully he will regret it in his old age.
Ashley Pomeroy: I can't wait for them to attach cameras to the athletes - it might slow 'em down a bit, but think about the possibilities. e.g. beach volleyball. What happens if two rival news agencies put robot cameras next to each other? Will they fight?

good one :D
is that shoulder really dislocated?
bokane: Yes, useful, but we're still waiting for the big secret of the series - how do you get them to stay still while you focus stack?
liquid nitrogen? :)
sir_bazz: So how is the data for the new IQ graphs compiled?
Looking at the 5D MkIII RAW noise, (noise reduction set to zero), it appears that the 5D MkIII, MkII and D800 actually produce more noise at all ISO's than the the APS-C sensor used in the Pentax K-5.
Am I reading the graph wrong or is the data wrong?http://g3.img-dpreview.com/C530CBEACF7C45B7AA198AF6D56F8C85.jpg
check out the minimal read noise for these sensors, you are right about the K5 http://www.sensorgen.info/
stanic042: someone probably from this company has attacked me via private message for criticism of their grammar used in this announcement..well if this is the way they intend to do business, so be it and I wish them many customers happy with their services :D
apparently you missed the word probablywhat made me write that was fact that the message was written in their native language and apart from swearing they said "don`t you do this to my business"

iudex: It is pleasing to read about a producer from my country on DPR. However the site needs to be finished in order to look more professional.P.S. I think the correct adjective is "slovak", not "slovakian".
adjective is slovak as well, slovakian is an incorrect, "dialect" form made up by people who don`t know the grammar because similar form is used e. g. "canadian", but you don`t call the country Canadia slovak is the language of slovaks
Rupert Bottomsworth: I wish they would get a native english speaker to proofread their website.
even the first word is in incorrect form "Slovakian", it should be "Slovak"...
cinefeel: I am surprised.
Turns out that with sensible processing and upscaling to 45MP the SD1 almost borders on 645D territory:
apart from DOF, the resolution is truly amazing, details like artifacts from screen-print are visible, which is comparable to the 645Dvery nice sensor Sigma!
