RED Alert


Some background here: Jim Jannard is the CEO of RED Digital Camera. He made his fortune by founding Oakley, the sunglasses-and-similar company. Jim's also into photography, so he founded another company, RED Digital Camera. According to Wikipedia, Jim likes to take pictures of his company-sponsored race cars, his dogs and his company jets. In short, our sort of bloke.

Anyway, we discussed here a while back how RED was threatening to shake up the industry with its emphasis on merging still and motion capture through the introduction of a new digital convergence device, the DSMC Scarlet & Epic camera systems. Jim's a bullish, "we will win this war" sort of chap, and it's easy to be seduced by what he says on the topic. However, I also mentioned that the big boys weren't standing still, and so was gratified to note that not long after both Canon and Nikon introduced new members of their own DSLR family that also now featured the ability to take HD video sequences.

Today, Jim revealed his counter attack. And it's no mere "sniping from behind a wall" sort of thing but rather a full-out, blitzkrieg-style frontal assault. Good stuff! Having fought his way into the professional video market, he's now heading out beyond those borders to conquer new territories.

You can look at the specifications and decide for yourself the pure technical merits at the sensor level, and there's plenty to look at! The FF35 looks very interesting, especially with 16 bit capture and a very decent resolution of 24 Mpix. Being RED, the other specification to look at though is the frame rate: from 1 to 30 fps .... which is very impressive indeed. Just imagine how fast that thing - somewhere in the lower-middle range of what's been announced - is pumping data when running at the full frame rate? Actually, you don't need to imagine, it's 1.44 Gbytes per second. Serious stuff.

However, there's another aspect to what's being announced here, and that's the complete modularisation of the camera's main components. The sensor block is of course separate from the lens but unlike a DSLR, RED's use of electronics instead of a mechanical shutter, combined with the lack of moving mirror mechanisms etc., makes this now a much more attractive proposition, more like the digital back approach applied by the likes of Hassleblad, Phase One and others.

Downsides? Price of course. The new Canon 5D Mk II is around $3,000 for a full-frame sensor, 6fps frame rates for still use and a very decent HD video capability thrown in. The FF35 RED sensor "brain" is listed at $12,000 alone, before you add the viewfinder, battery packs, control grip and the rest. And whilst we are looking for problems, I have no idea as to what the metering is like, how the autofocus operates or indeed any other the other aspects of the photgraphic capture process we take for taken for granted in current generation pro/am DSLRs. After all, even 24 Mpixels at 30 fps is pretty useless if what you are shooting remains out of focus 90% of the time. In the video world, all of this is more manageable than is often the case in the stills market, but again perhaps that's just old-world thinking. We will see when all this starts to roll-out in mid- to late-2009 and the classic camera users begin to get their hands on one.

Modularisation always comes at a price, regardless of who is producing it, and in many markets it's a price consumers are unwilling to pay. I think it's definitely the right way to go at the high-end, especially for this class of device that has to cover still and motion capture, but don't expect this particular innovation to work its way down the food chain very far. Built-in obsolescence is alive and well in the halls of Sony, Nikon and Canon, and that's where what most of us will continue to get our equipment fixes from.

Canon 1D Mark III: Field Review


As previously reported, between the two of us we generated 35+ Gb of images over the course of our two week trip to Africa. That’s a result of shooting roughly 4,000 pictures between the Canon 1D MkIII and a Rebel XTi. As detailed here, the Mk III survived a bit of an accident, and pretty much on day 1 in Tanzania to boot, that my 70-200 L lens did not, so right off the bat I guess it gets good marks for ruggedness and dependability! I’d also have to give it high marks for the way in which it repelled dust. When we were shooting in Arizona with my (now) old 20D, sensor dust was a real problem by the end of the trip, resulting in frames towards the back-end there that were almost unusable thanks to the files showing dust marks all across the skies. The 1D was both a) better sealed and b) had Canon’s vibrating “shake ‘n clean” sensor technology This two-pronged approach of prevention plus cure seemed to do the trick better than, say, just the sensor-shake piece that is in the Rebel. And just to to be clear, Africa is a pretty stern test in this regard! Safari roads are no more than dirt tracks that are fast turned into airborne dust plumes by the many tourist vehicles plying back-and-forth, something that is especially evident when you are parked trying to photograph something and they are driving past you. Add to that a constant need to change lenses and you have a recipe for slews of images spoiled by specks on the sensor. A big win for the 1D here, then.

Over the course of the trip I got to really like the form factor, size and weight. The extra heft helped balance longer lenses and overall the body quickly felt familiar, despite my first impression of the whole thing being a bit too large and cumbersome. Coming from the Mk II, say, you’d have absolutely no issues adjusting and even my switch from the 20D ultimately went well. Indeed, about the only thing I wish they would to improve the handling is to differentiate the buttons a bit more. I like to use a separate focus button, and I’m pleased to say that this body now has one, but, it’s small, tucked round a corner and I can’t quite reach it comfortably. I’d prefer Canon provided something a bit larger and with more feel than just yet-another-button so I can be confident on what I’m doing without having to pull the camera from my face to check which button I'm about to press. And copy that comment too for the ISO button. On the plus side, Canon have finally included the ISO reading in the viewfinder; on the minus side I kept hitting focus lock or something else when I was quickly trying to switch ISO settings.

One reason in particular why the ISO button got to bug me was that the biggest change in this generation of camera was the noise performance of the sensor, and hence the way it really did allow you to use the ISO setting as a third dimension to get the settings you want for aperture and speed. On my old 20D, going above ISO 200 means you quickly start to hit the law of diminishing returns as noise quickly becomes intrusive and severely impacts perceived image quality. However, once you figure out that on the Mk III, ISO 800 is very acceptable from a quality standpoint then all of a sudden you have degrees of freedom not available to you before to get good DOF combined with a shutter speed that will keep things pin-sharp. This really was a revelation, and indeed it took me more days than it should have done to push the ISO to those rarified levels above 400 because I just couldn’t get my head around what it would mean in terms of the results.

The other big change for me is overall picture quality: right out of Lightroom the images look significantly better than I’ve seen before. Image files are clear, well defined and smooth, much more so in fact than I’ve ever seen with my own camera, confirming the notion that it’s not how many pixels you have but the quality of the data flowing from each of them that ultimately matters most. (Quick aside: I wish Canon would produce a black-and-white only version of this sensor. Quite makes me drool to think of what it could produce once de-Beyer-ed.)

OK, onto the more controversial stuff. To say that there have been a lot of reports about the auto-focus capabilities of this body, both good and bad, is the biggest understatement since the Captain of the Titanic announced that they had hit a small piece of ice but that the ship was unsinkable and so everyone should just keep dancing, having a good time and not worrying about it. Just for the record, the sample I used was a body reported to have had the mirror fix applied and was running the latest version 1.2.3 firmware.

In short, when it worked well then the Mark III's autofocus was very good indeed. Focusing was generally fast and accurate, results borne out by looking at the files afterwards and on the same day so that I had some recollection of each frame sequence shot. I used both one-shot and AI, each mode working pretty much as I expected it to. It took me a day or two to be able to convert how the image looked on the LCD into what that meant for actual sharpness when viewed in Lightroom, but it soon became clear when the image, err, wouldn't be. (The frame shown on those on-camera LCDs is, I assume, still a JPG constructed on-the-fly and hence is compromised even before you look at it. Add to that the fact that it's being displayed on a 3 inch square screen then there’s a limit to how critically one can judge things in the field on an absolute basis.) However, I could certainly see things well enough to know when shots were not in focus which is really all you can - and some would argue, should - be doing whilst out taking pictures. Remember the mantra, “memory is cheap, the shots you miss by playing with the camera are not”.

Throughout the trip I largely used just the central focusing point (with surrounding AF assist) and recomposed once I had lock. I did use the full-up pattern from time to time but mostly stuck to rifle-shooting rather than shot-gunning (if that makes any sense?) However, I did experience some issues when either the contrast was a problem or, quite frankly, I was in the wrong mode for the subject being shot. Not perfect, therefore, but way better than I was used to with the 20D and perfectly easy to figure out what was going on once you knew it was happening. Again, I got better at sorting this out as the trip went on and really the only time things were particularly challenging was trying to catch, for example, white birds flying quickly across grey skies (i.e. low contrast and fast moving subjects).

Speed shooting? 10 FPS? “Bloody fast” is the short answer, and in all honesty I had the burst rate dialed down to more like 5 or 6 FPS for the entire trip. Animals just don’t move that quickly, but having said all that I’d love to try it at Laguna Seca, the surf beaches or somewhere else where there’s fast motion because I’m sure the results would be very impressive indeed. Hmm, in fact I might think about renting one again for the ALMS meeting at Laguna Seca in October. Stay tuned ….

Other stuff: very impressive battery life, even with significant chimping of pictures just shot. (Great LCD by the way, though you have to keep brightness cranked up in order to see it in strong daylight). Didn’t try live view so no comments there except that I could see it being useful. Never got to try it in low light, with a flash or otherwise push it in areas outside of just shooting animals doing whatever it was they happened to be doing at the time we showed up, so nothing more to add really outside of the basics.

Value for money when figuring a price close to $4k here in the US? I’m tempted … very tempted, in fact, as reverting to the 20D to photograph the new dog this past weekend was a real comedown. But another $4k is hard to justify today, especially given just how much we dented our finances by being away on safari. Think I’ll wait and see what the 5D replacement looks like before deciding (to be revealed to the press on 26th August?), and even then may wait for the 1D Mk IIIN to see what the next generation brings. However, it was absolutely worthwhile spending the $630 for three weeks rental so no regrets at all on that front. I ended up with better quality files that can withstand tighter cropping and that show lower noise, and that ultimately do better job of bring you back to what was a wonderful experience each and every day we were in-country.
