Lenses / Re: Zeiss 100 f/2 vs. Canon 85 f/1.2 II vs. Canon 135 f/2
« on: May 29, 2013, 07:17:15 AM »
I was going to recommend the 135L, but the Zeiss is a great piece of glass.  100mm also is also closer to your 35mm.  As somebody else pointed out, the gap between 35 and 135 is a big one.

+1
Every 2x in focal length results in 4x FoV. You can fit four 70mm lens frames inside one 35mm lens frame (sh :)ot from the same distance) and almost sixteen 135mm lens frames inside one 35mm lens frame.
No matter how good the Zeiss 100mm is, the Canon 135mm f/2L has great IQ AND it can autofocus which is a great plus for that focal length (until your subjects sit still).

Plus, one could get a 135mm f/2L and a 85 1/.8 (which is a very decent lens) for the price of Zeiss.

Keep in mind that the above come from someone who swears by his Zeiss Distagon 21mm 2.8.
However, I also have the above 2 mentioned Canon lenses and I am very happy with them  :)

It would be 6D and 24-105 for me. No dilemma!

If you go FF you will have no need to upgrade to FF later. You can built upon this system.

EF500mm f/5.6L IS DO (But with quality rivaling that of EF500mm f/4 L II)

One can only dream  ;D

I don't agree they sent a useless brochure. If I recall correctly you have 2 daughters, so the 2 Rebels - which by the way are of different size - would suit them both!
(OK may be in a few years)

Tempting, but I'm waiting for the SL1X.

I expect rumors should be popping any day now.
Hmmm, you'll wait!

SL1MkII
SL1MkIII
SL1MkIV

EOS Bodies - For Stills / Re: 1DX, 6D and 5D3 RAW files
« on: May 20, 2013, 08:46:00 PM »
May I take advantage of this thread - instead of opening a very similar one - and ask to include EOS 6D in  the equation.

Can someone comment on its raw files too (in relation to 1Dx and 5D3 raw files) ?

Thanks.

That's the problem with 3rd party manufacturers.

I'd say this is the problem with *2nd* party manufacturers (I guess the 1st party is us, the customers) - it would be no surprise if Canon, Nikon or whatever changes specs and didn't open their protocols just to +1 their own equipment. Luckily, the 3rd party just got smarter and Sigma now has an usb dock for lens fw updates...
That's a very welcome addition! Let the (lens manufacturers) competition begin  :)

That's the problem with 3rd party manufacturers. I have a nice Tokina ATX-28-70 f/2.8 which stopped working since my analog days Canon 50E. It continues to work fine on the old 6xx series and my EOS1n though!

Regarding teleconverters however I guess Canon could have done better.

Even if not regarding the f/5.6 constraint at least regarding the design that limits the Canon TCs use on specific few lenses.

EF-S 400 4 IS

Why not try the EF 300mm f/4L IS, as it is the equivalent of 480mm on a 1.6x crop body?
Maybe because it would be the equivalent of much more mm (actually 640) on a 1.6x crop body and some need it?

No, a theoretical EF-S 400mm lens on a 1.6x crop body would be the equivalent of 400mm.  Note: EF-S lenses, which is what the OP requested, can only be mounted on a 1.6x crop body, so there is no crop factor.
Actually there is crop factor:
EF-S10-22 gives the equivalent of 16-35 for example.
The difference is that EF-S lenses cannot be used on full frame and there is no spare glass in the sense that the imaging circle is not big enough for full frame. So the quality may (or may not depending on the lens) suffer at the very edges.

Finally I found time to test my 5D3 with a 300mm f/4 (non-iS) lens with EF2X II teleconverter.
The test was inside my house and not much light.

It worked fine  :)
More information about "not much light"

Shutter: 1/50 Aperture: f/8 ISO: 25600

According to an EV calculator I found it worked fine to 3.6EV.

Next step would probably be to use half the lights I used...

I was surprised that Canon hadn't included f/8 AF on that body right from the start. Perhaps they needed to iron out some issues first, I don't know.
+1 Same with the 1DX. As it was replacing 1D4 (at least!) it was very strange that they omitted this feature initially.

I don't like being an "early adopter" (although this firmware update is not exactly a totally new thing), but reading these comments has convinced me to go ahead and install it.
Firmware seems fine :)  Just read the instructions. The part at the end that says to remove the battery for a few seconds seems new to me. I remember members of this forum mentioning the same thing for the 7D upgrade but I do not remember this instruction for the 5DMkII firmware updates.

(Or there was and I simply omitted it and I didn't know it!! )
