Canon General / Re: More Canon Lens Mentions [CR2]
« on: October 11, 2014, 04:51:44 PM »
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?

Pricewatch Deals / Relevance?

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?

Then you can have a look at this: https://www.facebook.com/video.php?v=10152698112494763
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 SensorGen.info)

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

Maybe videographers aren't underwhelmed?

Maybe BIF or outdoor sport 'togs aren't underwhelmed?

I'm speculating that the 7d2 has a "mild refresh" of the sensor in the 70d ... and I hope I'm mistaken when actual in-depth reviews are available.

According to SensorGen.info, the DR of the 70d is 10.9 EV. That's actually LESS than the 7d or T3i with 18 mpix sensors and 2009 technology.

"Best of breed" APS-C sensors from Sony range from 13+ to 14 EV (for older D7000 which may be a misprint?)

I will admit that the AF system of the 7d2 looks very impressive for outdoor sports, but I'm not that much of a "sports shooter". The sports I do take tend to be indoor basketball.

I wouldn't consider the 7d2 to be all that suitable for indoor sports action ... based on it not having good enough high ISO. I again hope I'm proven wrong when in-depth reviews are available.

It will be interesting to see how long it takes 7d2 video technology and AF to "filter down" to the Rebel line.

My 2¢:
• If I owned a Rebel with one or two EF-S lenses, and
• was seriously thinking of upgrading to full-frame,
• I'd give very serious though to abandoning Canon and going to Nikon or Sony full-frames

YMMV

Outside my budget, but actually not as high as I was expecting.

Yawn. Looks like an upgrade to the 70d.

Third Party Manufacturers / Re: Samyang Teases New Lenses

f/2 or f/1.2?
F/2 should be either superb quality or really cheap - like give an opportunity to try out MF lenses for newbies.
F/1.2 sound interesting though.

I've been very happy with my Samyang 14mm for Canon f.f., and 8mm fisheye (which works well on f.f. with two part lens hood full removed, even though the description makes it seem like it is for crop 1.6)

I am very much more interested to see them market relatively slow f2 and f2.8 lenses for low price, rather than faster, less sharp f1.4 lenses like the 35mm and 85mm. Those are relatively expensive, and would seem to be a bear to focus with shallow DOF. However, they would have a bright image in the viewfinder.

I think a very interesting bundle of Nikon D810 + Samyang 14mm f2.8 and Samyang 50mm f2 would be appealing, at least to me. It would be a waste of the Nikon AF system, however.

15
Also smaller than Leica S2?

And perhaps the hypothetical EMF mount could accept EF lenses directly?  The image circle from EF primes might appear like a true 8mm fish-eye, but obviously be rectilinear.

My understanding of the existing T/S lenses is that they have the image circle of MF lenses.

Those T/S lenses could have T/S removed, have the EMF mount, with AF and maybe IS. Those could be the initial primes for the hypothetical  Canon MF.
