EOS Bodies / Re: Canon EOS 7D Mark II in 2014 [CR2]
« on: July 20, 2013, 12:20:04 PM »
I have a feeling the new 7d Mk II won't come in too much different than the original 7D body

I'll do a price guess poll once the specs are out as a [CR3] or from Canon :-) ... but remember the $3500 5d3 which also is an "above mainstream" model, everybody was surprised to shocked then. And since you can save thousands of $$$ (and weight/bulk) by not buying 600mm lenses with a crop body, Canon might want to take a premium for the "top of the line" birding and semi-pro sports model.

Well, I have an overall good feeling about the 7D Mk II.  I think they know they set the bar high when the original came out and given the popularity of the camera, my guess is that the Mk II won't be anything to sneeze at...   That being said, who knows!

Some Canon big shot also said so in a recent interview, they know after all the sensor and feature recycling (sans adding some gimmicks) it's time for them to have a showcase model again that shines without compromise... let's hope the 7d2 won't be so expensive that you could buy a used aps-h 1d4 for it, which afaik also isn't something to sneeze at :-p

Canon 17-40/L, when used as an UWA on FF gear, not as a standard lens on crop.
Why do you say this? I use the 17-40 as a standard lens on crop and it performs very well for the most part IMO, as I understand it it's biggest weakness is used at the wide end without stopping down on FF. Using it on crop negates most of this issue.
The 17-40 is Canon's best full frame WA zoom.

I'm using a 17-40L on crop as a standard zoom because I plan (for CR regulars yes, really :-p) to upgrade to ff sometime and most of all the L is sturdy and sealed which makes a great difference because I regularly shoot in snow and dusty/dirty outdoor conditions. Just be sure to replace the lens hood with a 83J...

... however @f4 the 17-40L is clearly lacking in sharpness and except for the above reasons I really wouldn't recommend it on crop, even though it has a very good price nowadays esp. with Canon cashback rebates.

I'll kick off with my Canon 28-70 f3.5-4.5 II  :)

I have to admit you beat me, but considering longevity I've been shooting with my 1992 28-105 mk1 (replaced the 35-135 which was too narrow) up until a couple of months ago :-) ... and it held up great, a bit soft @f3.5 but surprisingly ok @f8 on crop for walkaround shots.

Unfortunately I cannot say this for the even a bit older 100-300 4.5-5.6: the good ol' Canon usm doesn't help if the lens is so soft @300mm that cropping @100mm has better iq :-\ ... so it's now a nice paperweight, this is really a model from the analog days where you couldn't crop the picture with the click of a button.

Wow that makes soooo much more sense now. I don't know why it was so hard for me to grasp that DOF is a subjective quality of a photo, which is highly dependent upon the human eye.

Welcome to the club :-> ... my guess is that often we talk about "hard" nerd/tech stuff which is a nice distraction and sometimes very helpful if you need specific advice. But over all that, the elephant in the room gets overlooked, meaning that so much about photography is "soft", subjective and relative. The only time this regularly surfaces is if someone is cornered in an argument and states something beyond the original point like "Well, but a good photog can shoot great images with a 10d and tech details don't matter anyway."

IS is so much better than f/2.8 for landscape stuff, f/2.8 isn't much DOF. f/4.5-5.6 and IS does soooo much more.

When I started shooting macro, I had to realize how many things in the natural world actually move a tiny bit, I never realized until I tried longer exposure times. Often the same applies to landscape, IS doesn't freeze leaves from jiggling or water from waving. In this case, neither shallow dof *or* IS will help, what's really required is a high iso high dr camera which Canon doesn't have yet.

I think the 6D has been a good seller, and have not seen any stats that say otherwise.

Canon's interest in volume is secondary, as every company they're after profits. So the question is how far the 6d price drops after other enthusiast cameras with much better af are released (70d, 7d2) that also have good iq for most of us. If the profit margin becomes too small, they'll release a 6d2. They won't do it just for sticking a "new" badge on the 6d2 like the quick succession of Rebels though.

As for the 150k shutter cycles...I thought it was only 100k.  Also thought 100k rating was average, and the only body that's rated for more than 150k is the 1Dx, is it not?  Pretty sure the 5D3 is not rated for more than 150k.  In any case, that's still a lot of cycles.

Uhg, you're correct, the 6d has only a 100k rating, just like my 60d and the Nikon d600. I had 150k (like 5d3) in mind since I see the 6d as the "real" 5d2 successor which also has 150k... the 1d series have 200k or even 300k.

Indeed, I wonder how long it takes for yonguo to hack the RT system, not that I'm entirely sure it can be done though. I'm going to assume canon has built in lots of checks to prevent hacking it.

I'm also keen to see how long it takes to reverse engineer the rt protocol. Of course it theoretically *could* be prevented by Canon by using strong asymmetric cryptography (i.e. you cannot replay the communication, and each flash has a different key signed by Canon's secret master key).

Still, I wonder if Canon would really go to such lengths to screw 3rd party manufacturers - after all, cheaper 3rd party units (lenses, flashes) are also a strength of the Canon system vs. for example Pentax.

And I'm sorry that this basically excludes all non-mkiii owners, but ya'll haven't drank the Kool-aid yet.

Imho everybody who though about getting a 5d3 and then, considered the price, opted to skip it or go for a 6d/5d2 can have some valid opinion on this? So for me spending €3000+ on a 5d4 I'd like to have:

* red af servo indicator like they managed on the 1dx, but obviously weren't able to to on the 5d3
* spot metering linked to af point - yes, "1d feature", but should be very helpful for high contrast tracking
* rgb metering like Nikon & Canon 1d
* built-in rt controller (saving €300 st-e3 price & bulk)
* higher dynamic range at all iso, iso/res could stay as it is as far as I'm concerned

It is around f2.8 so when you shoot wider than that you get much shallower dof than you expect. As a follow on to this it is impossible to accurately manually focus an ultra fast lens with our standard focusing screens.

For once, I knew this, but I've got a question since you or neuro probably have tried these screens: Amazon customer reviews tell me that the effect of the more visible dof is not that large, while the effect of a darker vf for slower lenses is significant - bottom line to only get this screen if you shoot f1.2-f1.4 wide open very often, correct?

As you stop down with the DoF preview button pressed, the VF doesn't get dimmer, but the transmissive LCD gets progressively darker until ~f/2.5, then the whole VF starts getting darker, too.

... meaning the exchangeable screen for lesser cameras also has zero effect for f2.8 lenses, but only for f2.5 or faster? I was never able to research how large the effect of the screen is for what aperture, and unfortunately you cannot try these in a shop.

Fyi, don't know if this has been mentioned here: unlike other ml features this will *not* be ported to other cameras since only 5d3/7d have the required readout (for details see the pdf linked in the ml thread) :-\

DoF does not rely solely on optics, so badgerpiper's  statement is false. DoF relies on apparent aperture (optics) and subject magnification (optics, reproduction size and viewing distance).

Thank you very much that you are so persistent explaining it, simple /me really learned a lot in this thread from you and the links you posted, esp. http://www.josephjamesphotography.com/equivalence/light.htm#dof

I was mislead by the dof calculators that output a precise dof range, I never read the fine print :-> ... but on the other hand I knew that the apparent dof changes drastically with perceived image size (like from camera display -> large lcd and your distance from it) which actually requires you to take multiple shots of the same scene with different apertures to have the dof *you* want for every output situation you have in mind. The CoC explains this and having read about it I don't know how I could have ever thought dof would only depend on optics :-p

1873
or if that happens you might as well shoot JPGs.

But with jpeg you're loosing the ability to alter wb in post ... having said that, I also never use s/m-raw, it *would* be useful though if it'd be a crop mode like newer Nikon models have it if your tele lens is maxed out and you're discarding the off-center data anyway.

EOS Bodies - For Stills / Re: Move to full frame (6D) or New Lens?
« on: July 17, 2013, 06:58:57 PM »
but the bigest improvement will come with your 50 and 70-200.

I doubt the 50/1.8 makes a good ff lens, I have it and even on crop using only the center it's less than mediocre.

Thanks for your input. I have looked at the 5d2 and actually wanted it over the 6d for some of its features such as ergonomics and PC sync, but people still want a lot of money for 5d2s.

Yes, again same here - I cannot find a used 5d2 on the open market that has what I'd consider an ok price considering shutter count and the improvements of the 6d. I just mentioned because you might happen to know somebody who'd sell a 5d2 for an ok price to "good hands" of an enthusiast.

Part of me says to get the 24-70 first as I would need a standard zoom on the 6D, but part of me really wants to try out full frame. I thought about just getting an old 5Dc to try out full frame, but I figured it was more worth the money to get a current model camera. The 5D3 is currently more than I would like to spend if anyone was thinking to suggest that instead. Thoughts?!?

Same here, the unfortunate fact is: you need both, which results in quite a large investment over the also ok crop iq in good light. If you're lucky you might get a cheap 5d2 if you don't need the new 6d features (see  http://www.canonrumors.com/forum/index.php?topic=11309.0), and I'd advise the Tamron 24-70 over the Canon mk1 (the Tamron is as sharp or sharper and has IS, the better Canon af doesn't really matter on the 5d2/6d).

Getting the 24-70 is a good idea because the 6d price keeps dropping, while the lens prices are stable, it's just that this focal length is a bit awkward on crop. So look for lens rebates and used ff cameras...
