Photography (hardware & technical discussion thread)

Angry the Clown

Recommended Posts

So I thought we'd stop the post your photos thread from getting clogged with by tech talk by creating a dedicated hardware and technical discussion thread. There seems no better time to do so as we're not far from the official unveiling of Canon's 5D MK3 in Shanghai, but the leaks now appear to be coming in full force.

I'm very curious about the HDR mode. I wonder if that includes the revolutionary idea that one might wish to bracket more than 3 exposures at a time? If it does in-camera exposure merging, it had better output a 32bit HDR file. It would also be nice if they could get 1080p at 60fps. Also interested in the new AF system.


Curious that Nikon and Canon seemed to have switched roles. Nikon has been pushing low pixel count, high ISO for a while...now it appears that Canon is doing that. Anxious to see the noise levels.


Looks like they borrowed a lot from the 7D externally.

It's curious that RAW is randomly listed amongst other video codecs. I can only assume that it's a bit of a hodgepodge of information on the retailer's part as I can't imagine the mk3 could shoot RAW video.... could it? It'd have to be output to some kind of external device but it'd cause a bit of a stir. Frankly I'd happily just taking the benefits of the improved processing and sensor along with (hopeful) improvements to combat the "jello" wobble and moire as far as video goes.


Oh and to answer my earlier question, the DOF preview button has now been moved round to the lower right hand side.

I'll be very interested to see just when it ships. Ideally I'd love one in my hands by the end of May, but these things never seem to launch when they say they will. That said, I'd like to think that the still buoyant MKII market and the Nikon D800 release in March/April will push Canon to make sure they get it by June and in relatively decent supply.

Strong rumors that Canon will drop the MSRP of the Mark II by $400. If so, the used market could see sub $1600 for clean bodies.


There is also a pesky rumor that Canon will announce shortly a high-MP 5D (5D X?) to compete spec-for-spec with the D800. But doubtful we'll see something until after some solid D800 market numbers come back sometime in Q3-Q4 at the earliest.

Mk2 bodies are dropping already ahead of the announcement tomorrow morning with an official price drop apparently set for next week. Again, though I understand a company deliberately slowing shipments of a new product to increase demand, my hope is that supply would be relatively plentiful if Canon want to encourage people to pony up the alleged $3400 for the Mk3 body. Many, particularly those wanting video - who must surely make up majority of those keeping mk2 sales afloat right now - are just going to stick with that given the mk3s apparent rise in price if they remain hard to get between release and October/November. We'll have to see. I'll have a list of dealers I usually use on standby throughout the day tomorrow and will call them as soon as they advertise pre-orders. I'm expecting about £2400-2800 here in the UK. I'll endure the premium to get one asap as it would get a lot of use from me on jobs over the summer. I'm ready to go, and the moment it ships I will sell on the 7D to a good home. I've enjoyed the 7D greatly, but that MK3 spec is looking like what I've been wanting from a dSLR.


I've seen the rumours of an alternate 5D too. It might be wise if they're worried about the megapixel war, and it might server those working exclusively in portrait and wedding photography. I've also seen, bizarrely, rumours of an SLR body from Canon geared more towards video... Not sure I can see the point of that given the quality the 1DX and mk3 are likely to deliver at 1080p, and from there you've got their C300 body if you just want video.

Now up on the official US website:



On the video front:

Addressing the requests of the pros and building on the unprecedented success of its namesake, the EOS 5D Mark III captures HD video with a level of sophistication on par with professional movie cameras offering phenomenal performance on a DSLR. It offers both All-I and IPB compression, supports H.264/MPEG-4 AVC High Profile, and automatically splits files greater than 4GB (FAT specifications) for extended recording without interruption. It offers the option of timecoding during recording only (Rec Run) or at all times (Free Run), useful for multi-camera shoots. It also features improved sound recording adjustment capabilities, offering 64-step volume control accessible through the Quick Control screen during video shooting, plus a dedicated headphone jack for convenience in shooting. The CMOS sensor's new drive system significantly increases image processor performance, reducing color artifacts and moiré (a common problem that occurs in scenes with horizontal lines), and ensures that the EOS 5D Mark III can record at a number of frame rates up to ISO 25600 in H mode.


Press release can be found here:



B&H in the US now have it listed for pre-order confirming the $3499 price for the body.

But what's the "Lock" button for?


It locks input from the wheel in case you turn it accidentally. The same position as the 7d. Movie mode, still mode toggle and start/stop in the middle also from the 7d. Left side top power switch, 7d. I expect this will best the 7d in speed, which means this should be a wonderfully nimble camera. The 7d is way more fun [\I] to use than the 5d mkii. The mkiii is probably a blast to shoot with. $3,500 is a lot, though.


From the dpreview article linked above


AE Bracketing ±3 (2, 3, 5, 7 frames at 1/3 EV, 1/2 EV steps)

Some video and still samples from Canon Japan:




Nice "making ofs" each video too. Surprised in the first one - with some lovely b&w footage - the girl's bedroom is all natural light save for a tiny little LED lamp the cameraman's assistant is moving around. It's been graded well. More surprising actually is them focusing without a follow focus. Good of them to test the improvements to moire reduction.

My one disappointment is they did not increase flash sync speed. Alas, I think anything beyond 1/200-250 is a thing of the past. Otherwise, this is note for note the camera I want next. (And by "note" I don't mean dollar bills. FFS the price got jacked. The 5D II debuted at $2699!)

It'll be interesting to see if the price does it much harm. I'm betting the UK equivalent will be more expensive still and closer to $4000us. Again, I will grin and bear the premium to get one this spring. I could feasibly see a price drop around November IF it is harmed by its $3500 premium. Guess it also depends how photographers judge it against the D800/D800E as well I suppose.


Should know in a few hours what the UK price is.

Sweet zombie Jesus. Obligatory UK "kick you in the face repeatedly" markup on the Mk3 has priced it at £3000.... That's $4475 to you lot. So don't ANY of you complain about the damn price in front of me. :) Good grief.... The US $3500 is the equivalent of £2200 here. I'm still getting one, but hmpphhhh. I will have to apply some research and tactfulness as to precisely when and where I place my order.

The D800 does look very nice. My problem would be the investment I've made into Canon and Canon-mount glass, and the fact I'm now so accustomed to the Canon menu system and so on. It took me an age to get into digital SLRs and move on from film as some here may remember (7D was my first dSLR!) and so much of it was down to being intimidated by all the menus, and all the buttons! I'm happy now, I can work my way round Canon SLRs... but the thought of maybe starting over again with Nikons is a bit daunting.


I could have a couple of days in New York for the additional cost of the Mk3 in the UK and buy one over there. Tempting.

I do rather wish I could wait until both Mk3 and D800 have been on the market long enough for quality comparisons to be produced. That could help sway me, but time is a factor for me at the moment. D800 does seem to have more bang for the buck in certain regards, but then the step up for me from the 7D to a 5Dmk3 is surely better than it is for those with Mk2s looking to upgrade.
