EOS Bodies / Re: Canon EOS 70D Spec List [CR3]
« on: June 29, 2013, 07:56:45 AM »
I couldn't believe it either at first when I tried the 6d, and I am still wondering if I got it wrong: The fact that Canon forces the *source* files to be deleted is so impudent that it knocks your socks right off... and all reviews I know missed that, they only state "jpeg only" for hdr but don't say that it's impossible to do a custom hdr from raw afterwards in postprocessing and use the in-camera jpeg as a quick preview.
NOBODY.. really interested in HDR will do in camera HDR.

I dare to disagree, because there are two types of hdr I do:

* High quality hdr, I'm doing this a lot, often in combination with panorama or focus stacking. For this you just need the raw files, a lot of time and processing power & and end up with all raw sources plus a 100mb+ tif file.

* Quick hdr when I do some walkaround and know there's some higher dr in a static scene than the sensor can take (like the sun/sky/shadow, a reflection, ...) that doesn't require high quality postprocessing. For this I'd find in-camera hdr very useful because as far as I tried it the 6d/5d3 are very good at assembling the shots.

The problem with the 6d here is that you *have* to decide up front if you want to postprocess or do in-camera because it deletes all source files, jpeg as well as raw, and you end up only with a jpeg with known shortcomings in comparison like no way to adjust the wb afterwards. Deleting the source files as an option is ok if you're on holiday and don't want to fill your cards with 7x brackets, but being forced to do so imho is just ridiculous.

The 70D needs to be compelling and different enough to get lots of 1xxxD, xxxD and xxD users to upgrade to it. The 60D was very underwhelming in that regard.

Beyond any specs, the xxd line will always have customers like me who hate the Rebel ergonomics, small (grip) size, no back wheel, no top lcd, completely cripppled fw - I'd pay more just to not be bothered by these problems.

If it's like in the 5D3 then you can shoot the bracketed shots in RAW and get a preview in jpeg, then you can still use the RAW-files
True, but if it's like the 6D then you only get the Jpeg file :(
Oh I didn't know that.

Either way, the point remains that I would not expect an antenna under the display bezel (front face) to be significantly worse than an antenna on top, as that's the most common antenna orientation for devices like phones while you're using them.

GPS does not need to "look up".

In my experience gps doesn't *need* to look up, but it certainly works better the less matter there is between the gps sensor and the satellites. At least with my dedicated gps logger, more occlusion means less precision and/or more battery drain because the gps needs to keep trying to find a signal.

Either way, the point remains that I would not expect an antenna under the display bezel (front face) to be significantly worse than an antenna on top, as that's the most common antenna orientation for devices like phones while you're using them.

That point was already made by Dr. Neuro, and it's indeed a mystery to me why they put it next to the prism instead of under the lcd display ... but then again I never screwed my camera open to see how the wiring is how it's built.

I have to recheck my 600D ... I think it was the 650D and the EOS M where it started?!

I mixed that up, it was the 650d, the Rebels are in so quick succession I'm getting confused :->

I am not sure it is just for the video crowd - think about an "adjustment mode" which makes AFMA due to the comparison between the fast phase detect (via special unit) and sensor phase+contrast AF ...u

Canon might include some auto-afma adjustment mode, but that's the same thing Focal or Magic Lantern does right now, so no big deal - and it has nothing to do with the on-sensor phase detect because that should automatically sync with the on-sensor contrast af anyway.

The whole on-sensor af is really for video people who don't mf, still shooters on tripod or people hold their dsl(r) in non-reflex p&s mode. But I admit that if Canon should include a touch screen it'd be attractive that the camera instantly focuses where you touch, anywhere on the screen.

In science, once you have questionable data and your peers catch it, it raises red flags about all of your data.  This is very troublesome.

In science, when you are caught with your pants down you either discretely fix your study or discredit your peers :-> ... btw my favorite scam site btw is the German traumflieger.de who seem to simply make up their (surprisingly precise :-)) data out of thin air, proof is that they are able to measure the 70-300L @f4 @300mm, my copy cannot do that :-p

To me, this seems to be the same tech they started using on the 600d, but now the whole sensor is covered with phase detect pixels and they seem to be able to handle the high processing power demand.

This is great news for the video crowd, but bad news for traditional old-school still shooters like me who only use lv on tripod ... if Canon has the edge in lv/video af, they probably can get away with a straight viewfinder phase af copy from the 7d1 and nowhere near the -2ev/51pt-af of the d7100 :-\

IMO, this is all feature differentiation (and profiteering) by Canon - i.e. if you want GPS with this model, pay us for a GP-E2; we included it as a feature in that model to appeal to that particular market segment.

As usual, you might be correct - marketing is about squeezing as much money out of people but only up to the point when they'd feel ripped off or made fools of -  but if there is any seemingly compelling reason for cut specs will be readily accepted by the crowd, as just proven by me :-o

The 70D will hopefully provide a lot of bang for the buck... which will hopefully help fuel a healthy and continuing competition between major DSLR manufacturers for a decently priced 7DmkII eventually.

Don't hold your breath - Even if the 70d has an updated sensor+wifi over the 7d1 it will have a hard time competing against the 24mp/51pt-af Nikon d7100, even more than the "low light king" 6d vs d600... but of course that depends what price tag Canon has in mind.

I could be wrong.  Can you cite where Canon said that Wifi was the reason for no flash on the 6D?

I don't have a source either, but I suspect that gps is more of a reason than wifi because the chip needs to look up for obvious reasons ... for the same reason the 70d seems to have a flash, but lacks gps.

1958
if you will compare the 6D auto focus with my old 550D, then it's insane fast.

<sarcasm>Maybe we should just be more lenient with Canon and start comparing the 6d only with 6 year older camera, ignoring the fact that you can get three (3) current Rebel 700d for one (1) 6d :-> ... but sure enough the 6d will do just fine for high contrast objects moving in a predictable straight fashion in the center of the frame like the motor cycle you shot, you'll even only need a singe af point for that.</sarcasm>

But this proves that there are very different ideas what to do with a camera and if €1700 is a good price for what the 6d delivers, and a thread like this should help people sort out if the 6d is a good choice for them.

60D AF ----> Rebel.
7D AF ----> 70D

The base af is the same, but they do some tuning - for the 70d it'd be paramount that it's more precise than the 7d1 af (even 60d is better) and can use the enhanced precision of the latest Canon lenses like 70-300L  & 24-70L2 ... the 5d3/1dx can, the 5d2-copy af 6d cannot, let's hope for the best concerning new crop releases.

1960
Here is a capture from a 6D video... Nothing like that ever happened to me with the 5DMKIII or the 1DX.

Canon took great care to make the 5d3 an excellent video camera (with Magic Lantern :-)) and to make the 6d a stills (non-action) shooting camera, for my (lack of) money they could have just removed video alltogether and cut the price by €200.

You can plug a 3rd party aa filter into the 6d just like the 5d3, but considering the price you could also go straight for the 5d3... if people buy the 6d for video it's their own fault considering the well-known moire problem since the 20mp sensor isn't built to downsample like the 22mp version.

Keep in mind that while many people refer to the 5DII as a 9-pt system, it has 15 AF points.  Only 9 are selectable, the 6 'invisible' points sit between the center and the outer points, and are active only during AI Servo focusing (if enabled - they're off by default).  Now, I'm not saying the 5DII was actually good at handing off from the center to the outer points...but it was designed to do so.

That's what I intended to write :-) ... Canon tried on the 5d2 and failed, and they stopped trying on the 6d because the rationale is that anybody who wants a real multi-point af should buy the 5d3 (or a 1d4 or Nikon :->).

Dual memory card slots please.

Forget it, this is reserved for commercially usable "pro" bodies, it's Canon after all.

completely new sensor or just a revamped 18MP sensor, that´s the question. I hope for a smaller manufacturing process.

I don't care for the process if it's one *real* stop iso improvement with no strings attached, i.e. iso1600 looks like iso800 now inc. the dynamic range of the lower iso settings.

Is it just me or does that look like 7D to me?
No, it's not just you  8).
Except for the articulating LCD, this is basically the 7D ... with a new sensor.

The digic5-based cameras have many qualities that are not immediately visible in the core specs due to the higher cpu power: more continuous fps, in-camera ca correction, higher res burst pictures (with Magic Lantern), ... the question if Canon again chooses to cripple the firmware for a "consumer" model

What's not clear about 70D yet:
- AFMA is present or not
- body is magnesium alloy or not
- SD card slot speed

It will have afma after all the 60d complaints, body mag/"plastic" is overrated, and sd card speed of course will be uhs-1 (the 5d3 just happened to have a crippled controller, doesn't seem to be intentional on Canon's side).

... the best thing about the 70d though: If the price is somewhat reasonable it's a tough competition for the 6d and should bring the latter's price down.

Lenses / Re: 16-35 f/2.8II vs 17-40 f/4

I almost thought the lens was defective, actually, until I examined some of the shots I took at closer distance....weird.

This doesn't seem to be mutually exclusive to me - while it's true lenses show different sharpness depending on focus distance, the effect on your particular copy of the lens could very well be stronger than the average "standard" due to a defect or simply bad luck with a "bad copy".

Animal Kingdom / Re: Wildlife Tips?

You may want to consider using a flash.  A flash can add a catch light in the eyes and it can add fill for backlit critters (e.g., birds).

Good idea, I use flash all the time for this. But you also have to add a flash bracket to prevent drop shadows, to prevent red/green eyes on animals (it's surprising how many have reflective eye backgrounds) and to get the eye reflection away from the center which looks horrible "p&s-like".

1964
Did I include enough context for you?  I stated, "When I tried servo tracking with an outer point on the 6D, it would frequently start out in focus then drift successively to backfocusing as the kid ran closer," and subsequently, "With the center point on the 6D, the handoff to the outer points sometimes 'missed' and the outer point would lock onto a pipe on the wall or something."

I have to admit I find it valiant to have even expected this af system to hand over focus between the points as "real" multi-point af systems (5d3, d600, d7000) do :-) ... on the 9pt crop cameras the focus points are too far apart for focus handover to work in real life, but they interpolate the focus if the tracked object covers multiple points.

On the 5d2/6d I'd also rather expect the outer points to serve as helpers for the center to do some correction, but not to work as 11/9 real, independent but interconnected points... or did anyone get them to work that way (I'd be delighted)? With this af point spread it doesn't seem plausible for the camera firmware to be designed with "real" multi-point functionality in mind.

One interesting piece of information: Canon deactivated "focus patterns" on the 6d - with the 5d2 (and all 9pt crop cameras) you could select patterns with Magic Lantern like the 3 leftmost,  the 4 around the center and so on. Since this isn't possible anymore on the 6d it might be that Canon even in internal development expects the 6d to perform only ok in either "single/center point only" or "center + all other points as helpers", i.e. no real handover.

You shoot 8-10hours a day with a 60D....why?!

Because it's fun and you have to be patient with animals, frogs quak or yawn only so many times a day, wild horses run or relax only for some minutes, butterflies are in perfect light and position only for so many seconds, ...

Plus I'm learning how to do it and thus am not getting paid for it - hence I can either shoot or earn money :-p ... and 8-10h is not 365d/y but only in the peak summer season when I'm on holiday and the weather is good.

Get a battery grip.

I was always hesitant to buy more stuff that only fits my (old) 60d and cuts away the 60d's main advantage - size & weight... but well, I'll have to think about it I guess.

Fyi all: I Just looked up two pages on how to hold a dslr :-p and now I know why I have gotten around to do it otherwise - I lie flat on the ground a lot (handheld macro, animals) with the camera near ground level and putting the wrist under the camera isn't possible this way...
