Given that Canon is probably going to lay all their cards down in September

SLRgear has updated the Sigma 50 review since publishing the Otus.
The crop comparisons show well what tradeoffs Sigma made in designing this lens to be slightly less sharp but provide better microcontrast.
I like what I see from the Sigma more than from the Otus at this stage but for me a lens must balance sharpness and bokeh so I'll still buy the Sigma cuz it's cheaper.
from this excerpt, they agree
"All in all, this is a case where the raw test numbers doen't carry the entire message. For our money, we'd go with the slightly higher CA, lower sharpness, but higher micro contrast of the Sigma, even if the two lenses cost the same."
12 mp? Foveon or Bayer sensor? It's hard to believe that Sony, which got good reputation because of its high MP sensors, would go back to 12 mp camera
... I don't think these documents should be released, its a dangerous game and I don't think CR has the money or the power to fight a big corporation like Canon ... but be my guest and prove me wrong.I'm with you - it is a risky endeavour to release NDA'd or internal documents.
Think I'll bookmark this.
Might be useful next time I hear some litany about disservice from Nikon or Sony and how much more attentive Canon is to customers.
Oh yes because Nikon (D600) and Sony (just about everything from flaming TV's to laptops) don't have similar lists!
The optics of FE 24-70 f/4 are very much from ZEISS made by ZEISS, including the anti-reflective coating ... its just that the lens isn't all that good for the money they are charging, because of which some people speculate that ZEISS "only provide QC to Sony".
Just out of curiosity thanks to a conversation in Marketing 101 - why would a company like Sigma create products for other brands, specifically lenses for Canon? I'm curious about the thought process that went into a decision by such a company to create accessories and devices for someone else's products since they already have their own line of camera bodies...
Unfortunately, The Sony/Zeiss 24-70 f/4 OSS lens has received disappointing reviews at both photozone and SLRgear.
I read those reviews and that's pretty much what I feel about the FE 24-70 f/4 lens ... it is a good lens to have for about $700 (maybe $800 max, but no more) but for close to $1200 it is just not worth it, one might as well stick with the kit lens.
I would consider buying a flash that I can bounce off the ceiling if that's going to improve my indoor photos more than buying a faster lens would.
