Software & Accessories / Re: Adobe Lightroom 6 Coming Very Soon

Any info on whether there will be a new PV (process version)?

If Canon will produce a sensor with the dynamic range and relatively noiseless shadows of the Sony sensor, I will consider it. I did consider buying the Nikon D800 when it was first available. That was not because of the resolution which is excessive for most usage but for the quality of the image shadow details.
I really don't have much use for such high-resolution image files although I could change my mind if the dynamic range is an improvement.
Actually, I'd be happy if Canon could work out a license deal (like Nikon) and use something very similar to the Exmor 36 mpix.

For this EF 35mm f2 IS owner, no IS = no sale. I won't be getting a 50mm or 85mm until there are IS versions (and then only when the price comes down in 6 to 12+ months).

I would give almost anything for a sharp, reliable 50mm lens like the 35 IS

Same here.  I'd be ok with f1.8 or f2, but would really like a 1.4 version w/ IS.  That would be a killer walk around lens for me.  And, I think it could be similar in size to the 35mm IS, when looking at past lens sizing (I.e. 35 f2 vs 50 1.4), but I'm no physics expert  ;D

I am also a Huge Fan of my 35 IS.

Actually, I think a 50mm f1.8 IS would at most be about the size of the 35 IS, perhaps a bit smaller and less weight. (but I'm also not an optical engineer).

This may be heresy, but if you "only" make letter size 8.5x11" prints, the amount of cropping to turn a 35mm into a 50mm won't be noticed. Even with pixel peeping, my impression is that you would have to be relatively experienced and know what to look for to see much, if any, difference.

Further, my understanding is that there is NO scene that can be captured with a 50mm that a 35mm can't capture (with relatively minor cropping and NO zooming with your feet). The opposite isn't true. A scene where a 35mm FOV is perfect would take some compromises with a 50mm, if even possible (like can't back up).

So? Get the 35mm ... yesterday ... rather than waiting another 12 to 18+ months for a rumored 50mm f1.8 IS to come down from an introductory high price for pro's and well heeled early adapters, to under $500. Obviously, a f1.4 would be a somewhat more $$$.

And with minimal pano skills, my 35mm IS on 6d can become a "poor man's medium format camera with a very wide angle lens" (not uwa) with 10000+ x 3700  resolution in portrait mode. I'd think such a capture would be darn close to as sharp as a Pentax 45z with a native, prime very wide angle. Or not?

Note: pano-head and tripod recommended for interiors, and for scenes with prominent, large foreground is important. I've been using my pano-head less and less with some attention to detail to reduce stitching errors.

mmm, a lens that when used open wide means you either get a person's nose, eyes or ears in focus.

Am I the only one who would perhaps re-write that quote to something like:
either get the left eye or the right eye in focus ... maybe?

Me the practical one on a budget with no soul and/or nostalgia?  And at the threshold of WOW (wrath of wife : :o )

If both the f1.0 and my EF 35mm f2 IS were $500, and they both depreciated to $0 that day (no resale issues), I'm confident this 63 yo geezer would get more keepers with the 35mm. But I'm not into extreme shallow DOF. YWWV.

Reality (for me)? With a lot of practice, I might get 10 captures ... perhaps out of 1000+ ... that were different than anything else I'd ever taken, but then I'd perhaps lose interest after the novelty had worn off. Or not?

My experience with Yongnuo is mixed. The first flash seemed to work well, so I got another to use in Slave mode. Shortly after the 2nd one showed up, the first flash stopped working.

Also, the Guide number was significantly "optimistic" ... it might have put out half of rated power.

I just can't get interested in "zooms" with such a small zoom range (24 / 11 = ~ 2.2). To me, 3x zoom range is the "sweet spot" for sharpness and usability. Significantly less than 3x zoom range becomes a "who cares". YMMV.

With the well-reviewed and apparently popular EF-S 10-18, that is even more the case ... a "zoom" range of only 1.8. Why bother?

My inclination is to use a faster, sharper, FAR LESS EXPENSIVE uwa prime like the Samyang 14mm f2.8 on f.f., and "zoom with my feet" if possible,

Or, use cropping to get the equivalent of 11mm.

Or with static subjects, use the 14mm in portrait mode and stitch together 3+ images to get medium format IQ. I haven't done the math, but my speculation is that such a pano would be pretty close to the FOV of an 11mm FL on f.f.  Or not?

An alternate reading could be ...

"At Canon, we see impossible" ...
to overcome challenges to cost effectively match the performance of modern sensors with our obsolete fab.

Or not?

I'd be more interested in higher DR value than more mega-pixels.

I'd be pleased in Canon integrates the Sony Exmor 36 mpix sensor. Canon was willing to use the Sony 1" sensor in the recently announced G7x.

However, I'd think that use of high mega-pixels would tend to slow the FPS spec down, perhaps significantly. Or not?

Maybe I'm being slow, but I don't see the relevance of this article to CR.

Is Canon equipment used at the work-shop?

Thanks. Impressive, although I'm not informed enough to really know what to look for.

The original 7D was an amazing camera with a mediocre sensor
Mediocre by 2014 standards?

IIRC, the 2009 18 mpix 7d sensor was considered excellent, and exceeded expectations. I recall the DPR article about the 50d being underwhelming because the per-pixel IQ was less than the 10 mpx of the 40d. DPR declared the "end of the DSLR megapixel war" since the 15 mpix of the 50d wasn't really that much better, if any, from the 40d.

And then the 7d was released, with better per-pixel IQ than the 40d or 50d ... I really don't think people in 2009 considered the 7d's sensor to be "mediocre", except compared to the full frame 5d.

And then the Sony Exmor sensor started showing up in Nikons, like their excellent D7000.

...the 5DII was a mediocre camera with an amazing sensor
I'll agree that the AF of the 5d2 was underwhelming.

However, I haven't noticed the kind of "feeding frenzy" to pre-order a 5d2 on any other camera announcement. People were paying significantly over MSRP to get a NIB 5d2 on eBay.

Thanks for the link.

I'm mostly ignorant about video, but in that sample video, I didn't see what I consider to be a real challenge to follow focus ... a person running diagonally through the scene towards the camera, from upper left in the viewfinder to directly in front of the camera, and then running away from the camera to the upper right.

The movement of the dancers seemed mostly side to side, rather than front to back.

That challenge would be like a baseball video from a seat just behind first base, and the batter running to beat out a bunt from home plate to first base.

I wonder how the 70d does on such a challenge, and how the 7d2 will do.

Perhaps even more challenging ... tracking a single runner among multiple runners, like at an outdoor soccer game?

And more challenging? Indoor sports with multiple players running around, like basketball action?

As wildlife photographer there is a lot of important key features.
Agree, as long as the wildlife weren't moving around much in dim light.
think is as 1dx with smaller sensor.....

If the 1Dx had so-so high ISO from 2009 technology, and lower DR than the 7d's 18 mpix sensor (according to

I'm anxious to see what the new sensor has to offer. Hopefully, it's got more latitude than the 18 mpx it replaces.

Same here. My speculation is that the sensor will turn out to be a mildly refreshed 70d.

According to, the 70d at 10.9 ER actually has LESS DR than the 18 mpix sensor in the 7d and T2i (with 2009 technology)
