EOS Bodies - For Stills / Re: Canon EOS 6D Rating by DXOMark
« on: December 12, 2012, 02:08:18 PM »
Is it just me or does the 6D sensor slightly outperform the 5D3 sensor in dynamic range and is on par in everything else? Maybe Canon started moving and can improve their sensor performance after all.

Also need a 17 - 55 (approx) but the Canon f2.8 one is too expensive. Anyone know if the Sigma 17-50 2.8 is good?

The sigma is good, but it has some drawbacks. The focus ring only turns about a quarter from nearest to infinity. It's hard to impossible to focus a shot manually.

Also some photos are out of focus (phase AF, centerpoint) but i don't know if it's the error of the lens and if the tamron/canon lenses would have less focusing errors. In the reviews i hear no complaint about the autofocus that's just personal experience.

with the new lens series from sigma you donĀ“t need canon for that.
you can do it yourself.

Which means you don't need to have a camera with AFMA or software like FoCal??

Correct me if i'm wrong, but you use FoCal to estimate the error and then enter that number into the AFMA field of the camera. Now you replace the AFMA of the camera with the lens adjustment but you still need FoCal (or you just use magic lantern and jog the focus around manually).

Are Canon cameras still outselling Nikon cameras 10:1?

Does anyone know how many points the weather sealing is in the score?

It will all come down to the optical quality.  It has to about match the 100-400L at 400mm and f/5.6.  If it's substantially worse than that, and up-res of the 100-400L might beat it.
I kind of disagree, simply because this goes to 600mm. If it can match the 100-400 at f/5.6, then thats a really impressive feat, but, I think its equally important for it to be as sharp at 60mm as the 100-400 or 400 prime would be with a TC on. Cause if it is, then the fact it does it natively could be another leg up.

But really, the key is gonna be price. If its around the same price as the 200-500, then the range it gives might cause birders to go with it over the 100-400 (IS less important, and 600mm more critical than 400mm). Especially if a new 100-400 comes out and raises prices. If it costs more like $1300, then I can't see as many going with it

What I meant was, it'll have to be as good at 600mm and f/6.3 as the 100-400L is at 400mm and f/5.6.  If it's not, an upres of or teleconverter attached to the 100-400L could equal or beat the Tamron, making it pointless.

That is always the problem of cheap tele lenses. Even the 100-400L has no edge over a 300+1.4TC.

EOS Bodies / Re: 60D or t4i for video?
« on: October 22, 2012, 03:53:13 AM »
You should definitely have a look into magic lantern which doesn't support the 650D yet. (Or does it already?)

If you want to save yourself some money you could also look for the 550D/t2i which has the same sensor as the 60D. Even if it's just for a backup camera which you should have ready.

EOS Bodies - For Stills / Re: upgrading from rebel xsi: T4i or used 7D
« on: October 21, 2012, 05:14:49 AM »
Lower noise is only for JPEG photos. According to DXOmark the sensor itself is not better. RAW testshots look almost identical.

Do you need live video autofocus? If not i don't know a reason you should get the T4i.

EOS Bodies / Re: do crop sensors really add reach?
« on: October 20, 2012, 03:16:57 AM »
I'm confused about most the comments here.
Comparing a REBEL and a 7D to 5D II or 1DX is just not happening.

I have used all cameras and i would much rather crop pictures from a 5D II because of one simple reason.
The image quality from a rebel is simply put A LOAD OF CRAP. Doesn't matter how much reach you get if you only get to keep 1% of the pictures because of poor imqge quality. You can zoom in with 5D II pictures a whole lot and the image quality is still awesome!

And why exactly are your pictures shot with a rebel so bad? Is it because of the sensor or because you can't focus right?

"Quantities are limited so act fast"

Why should we act fast?

So Canon can get your money in this year's financial report.

Lenses / Re: Should I sell my 70-200L vii for the 85mm 1.2?

Then the 85 probably wouldn't get used. Maybe invest the money otherwise.

EOS Bodies / Re: Canon EOS-1D X Firmware 1.1.1 Now Available
« on: October 18, 2012, 02:23:43 AM »
I notice on the splash page, http://www.usa.canon.com/cusa/consumer/standard_display/EOS1DX_firmware, that the first lens listed as newly compatible with the 1.4x is the 70-300L. WTF? The two aren't physically compatible.  Does Canon want to boost service revenue by repairing broken elements?

You could us an extension tube between lens and extender for macro photography.

Most people don't need these "features" anyways and Canon is all about market share as i learn here every day.

Well they do matter for a few specific use cases. E.g. if you can't get the lighting right and need to brighten your pictures.

Those of you who defend DxO scores, why do you have Canon gear?
Because Canon offers the better package. It's not all about the sensor. It's the combination of the sensor, AF, ergonomics, processor and lenses. Similar to cars, where one company offers the better engine, but another company offers the better car. The best engine won't do the job if the car "sucks" ;)
You wouldn't go offroad with a racecar or wear slick tires in the mud.

Every job needs the right tool.
