Hi all, I've been following the site for a while now and just signed up today.
I'm looking at upgrading from my 600D which I have really enjoyed using and learning from.
Without seeing any real hands on reviews and images from the 70D quite yet, I am keen to hear some thoughts on which camera you guys think would be a good upgrade.
I am not interested in the video side of things, only stills photography. It is not something I do to make money, but I do get a lot of enjoyment from photography.
I like to shoot landscapes, but also with 2 young kids like to photograph them too.
I'm looking at either the 6D or the 70D when it comes out. I have a friend who shoots with a Nikon D800e and he always recommends the full frame route.
I'm also wondering if the price of the 6D will drop at all when the 70D is released.
I'm just interested in opinions either way.
In my opinion, nobody should have an opinion on the 70D just yet. Wait for hands on and some real testing.
The price has already dropped as low as it will go on the 6D, with B&H's current "deal" and $400 rebate. Not sure if you can take advantage of this if you are outside the USA, though. The only time the 6D's price will be lower, is when its own replacement gets close.
My vote is for the 6D, especially since you're only interested in stills photography, and you shoot landscape. Much debate exists over the 6D's autofocus ability, so I will now delve into that abyss for four paragraphs. My copy works just fine, even in servo mode in low light, whether with all points or center point. Certainly the outer points are the weak link, but at the 6D's price point (compared to Nikon's D600), I feel there is no significant difference in overall autofocus performance. The 7D's sensor (which the 70D is supposedly getting), however, might fare better...I have not done a side by side to test autofocus with one yet. I've only used the 7D on it's own.
Further on the above point...just two nights ago, I performed some servo tracking testing with my 135 f/2L lens on my 6D. With a bit of tweaking of the servo autofocus menu, at 4.5 frames per second, I was able to get 6 to 7 out of 10 shots at or near perfect focus...all points active. However, to achieve this I needed to keep the subject at or around the center point. But...With only a single outer AF point active, the number of sharp shots dropped to 3 out of 10. This is certainly what most of those who complain about the 6D's autofocus, are complaining about. Additionally, apparently there have been some samples of the 6D which included a faulty AF sensor. Not sure if Canon has officially commented on that. I would say, perhaps beware of samples with early production serial numbers. HOWEVER...there are also those people who just want to brow beat 6D users, in a lame attempt to convince them they wasted their money, and should have bought the 5D3 instead. Ignore these people; their minds are closed. They seem to lack photographic and technical ability.
The subject was a camera lens box on a moderately lit (a lot less than daytime sun intensity) table, indoors. Color temperature needed about 2600K, so that should indicate the low quality of the light. The movement was me, holding the camera and walking very swiftly toward the target. Shutter priority mode was 1/800, aperture varied between f/2 and f/2.2. Auto ISO varied between 12.8k and 20k. The results are more than adequate servo autofocus performance, compared to the 5D3, 1D4, and 1DX I have used. Apologies to those 6D haters out there, but it really does work adequately. On still targets in a comparably very very dark room, I was able to coax some auto focus out of the outer points, but it took time. The center point obviously worked fairly well. In a similar very low light situation (with the same 135L mounted), I could not get the 1D4 to AF at all, it hunted and gave up.
In bright daylight, servo autofocus via my 6D, can get between 7 and 10 out of 10 shots in perfect focus...depending on how difficult and busy the background lighting is...especially if that background has bright contrasty elements, and the target subject is dimly lit with very little contrast. So this is basically very close to the best autofocus available in bright light
...in my opinion...achieved with a much reviled AF sensor to boot. I will admit that there are probably situations with extremely fast moving targets, where my results would fall well below 7 out of 10 sharp shots in very bright light. But I have not encountered those yet. I'd like to. Some of these targets include machines that rev to 18,000 rpm and will visit the "Circuit of the Americas" in Texas later this year.
However, considering a purchase of the 6D, is dependent on how many full frame lenses you currently own, or are willing to buy. Price is a huge factor with them.
The advantages of the 6D as a full frame camera for landscape, should still prevail even over the new 70D with it's digic 6...especially since wide angle landscape will likely always be hindered by dedicated crop format wide angle lenses, with their inferior resolution and higher effective chromatic aberration (due to their lower quality of design, lower tolerances, and the CA is magnified by the smaller pixels of the crop format). I have owned and rented quite a few, none of them were stellar...some better than others.
However, if you use the best quality full frame wide angle lenses and are happy with the narrower FOV of a 1.6x crop, such as with a Zeiss 15mm f/2.8 (it might be the "best" overall wide angle lens currently available)...then I suppose a 70D could suffice, if you like its other qualities better than the 6D.
But...for low ISO, and/or longer exposure/tripod landscape imaging only...overall the Nikon D800E is certainly still the best body available. When the future high MP Canon body comes out, that will likely change...
but it should be priced well above the D800. So price could be a factor there, especially for a non-pro, or a part time pro who does not yet make big money, like myself. Not that I am considering Nikon...but it's low ISO performance advantage is real, and widely accepted on here. Nikon as a system, however, is not superior, and much of the time, inferior.
Oh, and as for high ISO performance (above 1600, but specifically between 2000 and 10,000...where low available light photography lives
), I say the 6D generates the cleanest files available in 35mm format. Depending on the specific ISO setting, I have found the 1DX's RAW files to have less chrominance noise than the 6D, but higher luminance noise (grain). Ditto for the 5D3, only it's slightly worse than the 1DX. Their grain is large in its structure, and thus it cannot be "reduced" without throwing away a lot of resolution. The 6D's grain at the pixel level, is much finer. Thus a bit more of it can be reduced in post editing, without throwing resolution out with it. The Nikon D600's noise performance, from the comparison samples I have seen, looks far worse with both types of noise, than any of these three Canons.
No doubt the 70D will have fine noise performance for a crop camera
, but whether or not it beats the Sony/Nikon 1.5x crop sensors, I don't know. It might only equal them, if that. That would still put it miles ahead of the 7D, and the T4i or T5i.
