the only thing I'd do differently about the 5D Mark III would be to have it be able to morph into the LX100 or G7X at the push of a button for when I don't feel like hauling around the weight or when the DSLR form is too obtrusive. Given that I can just purchase one of those for under $1K, and my 5DIII cost about $2K after trading in my 5DII, I see no reason to spend $10K on a supercamera.

Would I get dramatically better photos if the high-ISO IQ were doubled? focus speed was doubled? frame rate was doubled? nope. Whatever shots I'm not getting now, I probably still wouldn't get then, because I'm fairly confident the capabilities of the 5DIII as a camera exceed my capabilities as a photographer.

if coma, astig, and vignetting are good I'd happily buy this over the Canon 24 L II. all of the canon offerings make a very poor showing of the corners when doing wide-field astrophotography.

I know I'm going to get shouted down for this, but I wonder if it can do 720p/120fps video. my brother in-law shot some slow-mo video with his iPhone 5 at the shooting range the other day and all I could think about was how awesome it would be if we could get that on something with a decent-sized sensor and a high-utility lens. pretty sure this is on the S120 and the G16 but not the G1X, hopefully they can do it on the G1XII. even if they don't ... could still be the perfect backup camera to the 5DIII.

Perhaps it's a case of you-always-want-what-you-can't-have but I feel like Canon is totally missing the gauntlet just thrown by Tamron with the new 150-600. instead of covering the 70mm-100mm range yet again for the zillionth time, how about moving up into the 500mm or 600mm range for consumers and serious amateurs? I think that they will absolutely lose sales over this, not because the Tamron is amazing (although initial reports seem to show that it's pretty good at the least) but because Canon simply has zero competitive offerings in the focal length-to-price class. How about a 500mm f/5.6 L prime to replace the 400mm f/5.6? How about matching the 150-600mm variable aperture, or a 200-600, or a 150-500?

I know that the Tamron is just hitting and it will take some time for Canon to rework its lens designs and patents. I also know it's easy for webgeeks to sit and critique decisions that were probably made for very good reasons based on more factors than we will ever know about. But I seriously think Canon has been short-sighted in assuming that the 400mm maximum focal length would satisfy amateur photographers forever. Just because that was a realistic assumption 20 years ago doesn't mean it's a realistic assumption now. I have way more confidence in Sigma creating a competitor to the new Tammy than Canon at this point; can't wait until Sigma waves their new magic wand over the Bigma lineup.

If these perform at the level of the 35 f1.4 I will be looking forward to buying both

I'd be less worried about whether the lens is stolen or not, and more worried about whether or not this lens even actually exists. the whole thing could be a scam, as the old "if it's too good to be true..." adage holds up very well with photography gear on the internet.

Realistically I think we're looking at $7500 to $9000 for this

Lenses / Re: Is the upcoming 50mm F/2 IS USM for me?
« on: April 03, 2013, 09:11:33 AM »
I would think that they could make it a 50mm f/1.8 IS or even a 50mm f/1.4 IS, sticking with their current product positioning trend. a 50mm f/2 actually seems a little slow for what they should technically be able to accomplish.

I personally just bought the 35mm f/2 IS to serve as a walkaround on a 5D Mark III as the trusty ol' 24-70mm f/2.8 L was far too bulky and too intimidating for many situations. it's a great lens, the IS works well, the resolution is excellent. color and contrast are good, contrast may actually be a bit overdone for my tastes, but the images certainly have 'pop' straight out of the camera.

I tried the 24mm f/2.8 IS in the store and it also looked good, but I have far too much overlap at the 24mm f/2.8 position already, with the 24-70 L and the 16-35 L. a 50mm f/2 IS should be good but I wouldn't trade my 50 f/1.4 in for it. frankly, even if it's a 50mm f/1.4 IS, I would trade my current 1.4 in for it, but it would at least make a more compelling argument for upgrade.

I finally got a great deal on trade-in gear and made the switch from 5DII to 5D Mark III ... and I gotta say, if the D800 is any better, then it must be an insanely good camera. did some shooting at 1-stop underexposed at ISO 6400 last night with the new 35mm f/2 IS and yes, while the blacks are a bit crushed (I feel this also has something to do with the lens, the 35 f/2 IS is ridiculously contrasty, maybe almost a little too much so), there is excellent detail in the areas where it matters and the files from the 5D Mark III clean up far nicer than the ones from the II in terms of noise reduction. back when I was comparison shopping, it looked like the 5D Mark III had a 2/3-stop advantage over the 5D Mark II in terms of sensor performance based on web charts (dpreview and the like), but I'm finding in real-world usage, it's functionally a 1, maybe 1-1/3 stop advantage in terms of true usability.

I haven't done enough architectural/landscape work with it yet to tell if the dynamic range is improved over the 5D II, but from the bit of work I have done so far, it looks pretty good. I've shot far more restrictive film formats before so dynamic range, limited or not, doesn't bother me. I do think more is always better, but for those folks on here clamoring that the dynamic range limitations of the Canon are a deal-breaker are definitely exaggerating. please look at the work of Galen Rowell to see how dynamic range is controlled at the point of capture. and if you claim that it's too cumbersome, remember that half the time he was photographing in locations that he either had to ski to get to, hike to get to, or be roped in to get to.

I've stopped using Long Exposure Noise Reduction because I realized it wasn't actually time effective. when shooting, it closes the shutter for a time equal to the exposure time to try and figure out how much noise to subtract. as Aglet pointed out, it's really mainly just to remove the hot pixels.

I've discovered that when night shooting, I'll typically shoot numerous frames of around 5 to 10 minute exposures, of which I only select a couple to really work on in post. removing the hot pixels manually takes me only a few minutes per frame, whereas a 45-minute series of shots would cost me an extra 45 minutes in the field of waiting for the long exposure noise reduction to do its thing. totally not worth the time, just clean hot pixels in post and use a decent noise removal plug-in.

empirical test-wise, I don't think anyone is going to argue that Canon is slightly behind Sony/Nikon in terms of dynamic range recorded by their sensors.

the argument is whether or not it's a deal-breaker. I think if the photographer is uneducated, lazy, or lacking key tools, then yes, it could be construed as a deal-breaker. but if you're really taking your work (paid work or personal artistic work) seriously, it should not present itself as any sort of impedance. people took amazing photos on slide film back in the day. I won't claim to be someone who took amazing slide film photographs, but I did use it for architectural work and I devised ways of working within its narrow dynamic range, the though process of which greatly improved the quality of my photos.

this is like a 180-degree u-turn from the previous rumors about the 7D Mark II being a huge leap forward rather than an incremental step up. is this perhaps the 70D instead? that would be a whole lot more exciting.

I'm not sure this is much of a disappointment, since as far as I understand the optical design is unchanged from the existing model. And we can be sure the new one will be significantly more expensive. Of course we have to wait and see if this is how it plays out.

I'm more annoyed the street price dropped some 20% since I bought the current version, but have no regrets as it is a good leans already.

Where did you read that it was the same optical formula?  I'm not doubting you - I just hadn't read that and was curious.

if you compare the lens diagram that sigma posted for the new one, and the lens diagram they posted for the old one, it's the exact same diagram.

I usually use it only from about 16 to 28mm, because my version is not very good at 35mm

that's exactly consistent with my experience of the lens. if I need to go mostly 24mm and above, it's really not worth using the 16-35, I go to the 24-70 instead. but for the wider-than-24 range it's fairly unmatchable in terms of flexibility if you're using a Canon camera
