EOS Bodies - For Video / Re: Canon 6d for video?
« on: November 20, 2012, 05:56:35 AM »
However the 5d mark II is down in price. Should I go with the 5d and save the money for an additional lens? Do you think it will go down even more when the 6d is released in December?

The big advantage of the 5d2 is that it runs Magic Lantern which adds a decisive edge esp. for video, it won't be available for the 6d for some time (if ever). And since both don't have swivel screens and are outgunned by newer and less expensive video-only solutions the cheaper (used?) 5d2 should be a good choice. The only known problem is aliasing which has been fixed on the 5d3 (and probably on the 6d, too, we'll see).

EOS Bodies - For Stills / Re: dpreview 6D samples

i only speak about low iso.. im not needing these incredible high isos for my shots. and like the 5D MK3 i see no real improvement compared to the 5D MK2... not in these samples.

And that wasn't to be expected - for lower iso shots the 5d2 should be great (actually even little better than the 5d3). But most people who upgrade to ff want to have the medium-high iso capability, meaning ~6400 which is exactly what is really missing from the crop sensors and in this region there is an improvement over the 5d2. I agree crazy-high iso speeds are mainly for marketing.

Lenses / Getting a used L lens in long-term production
« on: November 20, 2012, 05:33:34 AM »
I'd like to purchase a used 17-40L because I need some uwa for ff (group portraits in close quarters & some landscape). It might not see much use since I'll most likely get the Canon 24-70/2.8ii for most shots, so I'd like to save some $$$ on the uwa. And the 17-40L will do on my 60d if I don't want to walk around with €4000-€5000 gear.

Question: The 17-40L is in production for a long time, do you think a newer sample has an advantage over an older one because there were some optimizations in the production? I'm puzzled because most offers are rather expensive (80% of new) and they're all in "good condition" yadayadayada... so if you have any other hints please feel free to share :-)

Previously in another thread, I've raised the possibility that 6D is built on an entirely new generation of sensor.

Definitely not, this was already ack'ed by Canon - it's the same sensor tech, though the 6d has a bit little larger pixels for the loss in resolution. The reason probably is that after the criticism about the lack of advancement 5d2->5d3 Canon had a 3/4 year time to optimize everything else.

The 6D shots might be a little bit underexposed compared to 5D3 but nevertheless

If you look at the exif data, all 6d shots have a shorter exposure time then the 5d3...

but small differences in image parameters between a consumer and a pro camera.

However, this shows how desperate the Canon crowd is for sensor advancement ... the Nikon competition obviously has left its mark :-> ... and again, imho there is no fixed distinction between "pro" or not except for marketing, why not use the 6d if it is at least as good or even better (low light af) for some shots?

for someone like me coming from a 50D this looks like a dream come true.  :)

Given that nowadays the camera upgrades are incremental, it pays to wait a little to wait ($$$ and iq-wise) :-) ... and even with the 60d it's the same, if the 6d has 1 usable stop more than the 5d2 that's good news and a reason to get the newer gear.

it's nice to know that Canon has given DPReview a per-production camera to play with.

Where did you get this information? Everywhere I look it has the "The camera used for this gallery was pre-production, and image quality should be considered 'Beta' standard" notice, though that probably only means the in-camera raw-converter / jpeg-engine and not the sensor hardware.

Picture below was shot at f11 with 250W studio light, not the best but it does show how sharp the 5D III can produce.

At iso 100 like your shot you hardly need a 5d3 to produce a good result (actually the 5d2 is said to be a bit sharper at low iso due to the weaker aa filter). Esp. for studio shots putting money into a sharp lens might be smarter than the newest camera body...

The jpeg iso samples of dpreview are to compare noise, in the way that you can see what's left of the details after nr.  I guess dpreview is a reliable site and they had the same setup, and imho the 6d is indeed visibly better in these shots (detail left and noise in background) - I just loaded all into lightroom and compared them side by side.

So either Canon at last really did something about their sonsors (rejoice!) or the 5d3 shots were done with an older firmware version that had a worse in-camera jpeg converter - we have to wait for a 6d software raw converter and raw shots to be sure.

Well, unfortunately they did extremely heavy global nr on the shots again (compare the details on iso 50 to the other studio shots), obviously to them a noise-free black background is more important than details :-x ... hail to raw and the LR nr brush!

But looking at the iso samples it might be clean 6400 and the the 51200 iso shot look better than 6400 on my 60d, so if it's a 3 stop improvement over the current crop sensor I'd say that's a definitive step up :-) ... on the other hand side we don't know how the dynamic range degrades @high iso.

Actually....the 6d seems to have this same problem...just saw a thread on it. I guess Canon fixed one thing and
broke another (the response to focus assist infrared).

Can you give the link to the 6d thread?

I wonder if the 6d could really have the same problem given the fact that it uses nearly the same af as the 5d (minus some af assist points, plus better center low light af). I'm ok if it doesn't af in my bathroom, but it should be able to do dark meetings/receptions :->

Btw: Did you use a 600rt for your test? What af mode (single point/all/...)?

People want to see sharpness and contrast and color what good just showing they wax-look processed model shot?

Which people - you did a survey? And international tastes might be different, the Canon (a Japanese company) shots remind me of the Japanese 6d amateur samples that are on flickr - way too much noise reduction and "wax look", but maybe more Japanese people like it this way?

And not all lens buyers are gearheads, they see a "nice" picture and think "I want to have this lens so I can take such a nice picture, too" no matter how the corner sharpness is.

That fix is not acceptable...if you set to release priority...you get oof images half the time....so that really defeats
the reason for buying a camera with supposedly better af....what a farce!

Actually that was exactly my thought when I read it, but since I don't own a 5d3 (yet) and just am trying to figure out if to get a 6d instead it's hard to say if people are either protective of their expensive investment or - the other side - overcompensating and bashing it because of disappointment. Unfortunately this issue is not something I can test myself in a photo store, so I have to rely on owner's opinions.

The other problem is to define "low light" because nowadays photogs aren't running around with light meters anymore, so that's another cause for the contradicting opinions on how serious this is (with or without af assist).

Last not least, Canon ignoring this either means it's a non-issue silently fixed in the next fw or a really serious problem :-p

Lenses / Re: How long and how much: new 100-400L

Any experiences? Anything specific I should check?
Without expensive equipment it is very difficult to tell how good your specific sample is (I had this problem when I bought my 70-300L). The one method I could imagine and tired is compare the new lens to an older one that you know is a good copy and sharp (in my case the 100L). Then match this difference to the expected difference from the iso crops of http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx ... and if you are not satisfied try afma or replace the new lens.

Just joined this forum because of this particular discussion. Just bought a 5d3 and used it this weekend at reception. Boy...this thing is bad when using single point af and flash

The fix supposedly is not to wait for the af confirmation, but just press the shutter with release priority because the camera has finished focusing way before it confirms it (see the posts above for the original post of this method).

Does this method work for you? It's interesting to me because that would really be a reason to get the cheaper 6d over the 5d3 for me, esp. if Canon doesn't ack this problem or comes up with a firmware fix.

EOS Bodies / Re: 6D Coming Nov. 30th?
« on: November 19, 2012, 10:07:58 AM »
the sooner the better! hope for some xmas promotions as well! but probably not..

Since a lot of people who want Canon, but not the €3000 5d3 or older 5d2 are waiting for the 6d, I guess there won't be any promotions or price drops for ~2 month after general availability.

I have I question: Do you have a tip for a good softbox that works with my 430EX ii, 580EX ii, and 600EX RT? The way I intend to use it most, is to place the flash and softbox on a monopod to get portaits outside, so the softbox must not be so big that a person cannot hold it for a resonably timespan.

What's wrong with the vanilla commercial softboxes? Look @amazon, their weight is between 500-1500g (depending on size).  Your only problem might be that they consume much flash power so the 430ex2 could be underpowered for daylight outdoor shots.

24-70 is not equal to 24-70 ... it will be interesting to see how long and wide the f4 lens goes in comparison to the mk2 f2.8.

That's because the f2.8 mk2 is noticeably more limited in zoom range than the mk1 - so in all fairness you have to compare the mk2 distortion and edge sharpness to the mk1 @26mm or @66mm (numbers are rough guesses) ... same might be true for the new f4 lens.

I'm not impressed with the 24-70 images at all..

The imho most unimpressive shot is the "macro" one because of very mediocre sharpness @f4, though the bokeh is nice. And the lens has a very short working distance, so the object is lit from the side and back.
