Reviews / Re: Review - Canon EF 50 f/1.2L
« on: January 16, 2013, 09:20:03 PM »
As you can se, 50/1,2 are less sharp than 50/1.4  at F-1,4

You have to select the 2nd 50L sample, the first one is a "bad copy":

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=403&Camera=453&Sample=1&FLI=0&API=0&LensComp=403&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0

The center is better on the 50L and there is less haze in shots i've taken from the 50L vs the 1.4.

Somehow the intra-Canon dogfight between the 50L and the old and rather crappy 50/1.4 seems a little strange to me, if there is a cheaper alternative it'd be the Sigma:

I also used a portion of the savings to scoop up an EF 85mm f/1.8 which I am really enjoying too.

Well, this is off topic, but I'm putting the saved money into a 17-40L, a flash bracket/diffuser and nd + polarizer filters that are incredibly expensive for 82mm - after long considerations that should result in better (at least more versatile) pictures than getting the most shiny camera body which is like burning cash.

But I wish everyone with a 5d3 luck solving this problem, if Canon should really ignore things like this and get away it's not good for any Canon shooter.

Again....it should be considered as 1point AF camera.

I partly disagree, it simply depends on the possibility of re-taking the shot or not - for "mission critical" shots the outer af points are probably out of the question, but if you want less focus & recompose with shallow dof and then review/retake the "extra" 10 points should be nice to have. And for tracking in good light it's most likely better to select more af points because the camera interpolates between them and single point af might loose focus faster.

Off topic, too: For peace of mind, it's best not to think of any other dslrs or competing brands out there.

I would love to be wrong and see some major changes in the next firmware release!!

The next 5d3 firmware release is scheduled for sometime in April (2013 afaik :-)) - maybe they'll do a silent fix by then, let's wait and see ... but I've decided to save the €1000 and get a 6d anyway, so for me it's more like general interest in Canon reacting or not.

Considering the amount of posts and information that is already here in this thread and several other threads, what do you think the chances are that someone from Canon that is reading the posts on the Canon forum might simply click over and read  the CR threads if the links are posted on their forum?  Just sayin'...

Personally I doubt the really important people who could actually fix things (i.e. the Japanese devs) read the US Canon forum either - with the lack of easy reproducibility some really important photog or tester would have to step on their toes so they actually try to provoke the problem, otherwise the "don't ask, don't tell" solution comes to mind... some mod in the Canon forum writing some comforting words imho doesn't mean anything.

I must have missed that because I haven't seen where anybody said a newer camera necessarily have a better sensor across all aspects.

Oh my, please don't be too picky, I don't deliberate too long over everything I write here and it's a recreational rumors thread - but there was talk of "significant iq improvements" somewhere in the vicinity of your name :-> ... I read this not only concerning snr and thus responded also to dr/sharpness, please do forgive me if I misunderstood.

Just be carefull quoting the internet categorically without actually having first hand experience

Thanks for the information concerning your 5d3 experiences, it's in line with what I've read here before. Though I don't think a "hands on" experience is necessarily more valid than a research across multiple sources, just because it's published on the Internet doesn't mean it has to be wrong.... and btw what you're writing is in the Internet, too :-p

I put less than zero credability into any of these back of the lens cap naval gazing DR tests people seem obsessed about.

Me, too (believe it or not :-)), I already wrote the differences are too tiny to really matter - I only mentioned it because a user wrote that newer cameras necessarily have a better sensor across all aspects, and this simply isn't correct.

It is sensor data, and 6D is slightly better than 1dx at base iso regarding DR,  11,5 compared to 11.2

Yes, I saw that, but who shoots at base iso anyway if it's no different from iso 800 except for a little more more dr (and high dr scenes require hdr anyway)? That's why I looked at higher iso levels, and here the sports-oriented 1dx seems to be the best of the bunch by a small margin.

You can gp to http://home.comcast.net/~nikond70/Charts/PDR.htm

Doesn't include the 6d (yet), that's why I was asking for other charts - thanks!

You can read about different sensors  QE and DR here http://www.sensorgen.info
Thanks for the link - does their testing method include the full highlight recovery available in raw?

The sensor in 6D is the  best sensor from Canon today
... except for the 1dx (as far as I understand the figures).

About 6D. Anyone who uses low-ISO shadows, they will appreciate, like the much lessened banding noise, and if you like to use 800 and above you will like  the  lower noise, including banding noise and if you like  to crop or print large will find more usable and real detail.
I'm looking forward to my 6d purchase (once the early adopters premium is gone) :-) ... that's because if anything really kills my shots on the 60d it's banding when raising shadows, iso noise can be somewhat disguised if the final output size is small.

I have no virus or spyware on my PC, so that is not the problem.

How would you know :-> ... anyway, never came across that problem myself and you're giving too few pieces of information (browser type, version, installed addons and so on)

Do you own these cameras or are you quoting the internet?

You see most of my equipment under to the left - and I already stated that the dr comparison is from the traumflieger review. Also see here, the 6d has ~1 more stop of dr at higher iso: http://www.sensorgen.info/ ... though of course I cannot verify the validity of their testing and methods.

iso 100:
5d2 - 11.2 dr
5d3 - 11.0 dr (like 6d @iso 800)
6d - 11.5 dr

iso 6400:
5d2 - 8.3 dr
5d3 - 8.5 dr
6d - 9.3 dr

The said review is very definite on the spatial resolution test, and at least this falls in line with what the CR user mst (Canon beta tester) often wrote and what I've seen myself when looking at 5d2/5d3 sample raw shots.

highest  QE  and DR

Could you please post the link to the 6d dr curve (and comparisons to 5d3/5d2)? Thx.

Lenses / Re: 70-300L with Kenko 1.4 TC on 6D
« on: January 16, 2013, 04:48:50 PM »
I have a bad a reputation at work for "damaging (my own) camera gear" so my buddies with cameras don't like lending me stuff for too long :)

:-> me, too - but here the Kenko tc is also a good purchase - it's rather inexpensive, sturdy, very compact (in comparison to Canon's tc) and should be hard to damage since the glass is not protruding but safe in the tc's center.

In the mean time I am shooting great photos and avoiding making sweeping generalizations about my peers.

Well, I did try to limit the generalization a little and of course it's just my 2ct personal opinion in a rumors forum. No doubt you can take great shots with a 5d3, 60d (my current camera) or 6d (my next camera). But imho it's like with all tech advancement, people on the older/current tech often seem to like to stick to the status quo, like b/w->color tv, horse carts->motor cars - you seem to be an exception to the rule if you say you'd like to have d800 specs.

At bottom, a super wide DR gives one a RAW that looks dreadfully flat not gloriously beautiful.

As long as the bit depth rises to 16bit, I don't see any problems with higher dr sensors - dropping data is easy, adding it after highlights are blown and shadows are noisy is another matter :-o

Why you need new Canon sensors like every year? If they pump out something awesome every 5 years im down with that. Would be crap if my new FF purchase would be blown away by next years release.

That's just it - the current Canon sensor tech is 5 years old (5d2-gen, recycled in 5d3/6d) - Canon is bound to make a big leap this or at least next year, if not for the sake of tech advancement then to keep up with the competition. The 1dx sensor with might be the first indication, it has other tech as the iso->dr curve shows.

You would expect the 5DIII to perform better than the 6D being that the latter is what I consider the Rebel of full frame

"Better" is relative here - the 6d gains a little higher iso capability (maybe about 1/3 stop) but produces less sharp images than the 5d3, so it's about what people want from a ff sensor. To me, the 6d appears like a downgraded 5d3 sensor with some readout adjustments and forced chroma noise reduction even in lower iso modes (in higher iso modes, the 5d3 also has nr in raw).

Can you show me where the mk ii beats the mk iii?

The 5d2 has a higher dynamic range (highlight recovery) and spatial resolution (i.e. sharpness) in low iso modes, even with the little less mp count than the 5d3. This fact has been known for long, Canon changed the iso/mp/dr tradeoff to gain better high iso performance and probably less banding on the 5d3 - all these ff models basically all use the same sensor tech. Since ff is about higher iso shooting it's a smart move, but I recon most 5d3/6d owners don't really want to know anyway :-p

The best proof of this I know is a recent German 6d review one on traumflieger.de - but the differences between the 3 ff bodies are not large enough to make a decisive difference for potential buyers, but it proves the point.
