Canon General / Re: Sony A7 + Canon 24-70 f2.8 L II
« on: December 16, 2014, 04:26:41 PM »
Hi,

Does anyone have this combination with the newest Metabones adapter?
I am curious as to how the autofocus performs.

Thanks

Have you ever consider their native FE lenses? It gives you a must better balance and faster AF. With Canon L + adaptor, I just don't see the point of going mirrorless system.

In the past, I had used a7 and a7r with:
1. Canon lenses + adaptor
2. Sony/Zeiss A-mount
3. and of course, native FE 35mm and 55mm

It took all the funs away when not using proper lenses on that mirrorless system.

The point is to use all of your world-class Canon glass against a 36MP sensor with "14.1 EVs" of dynamic range.  :)

I agree with Dylan777 that the Sony FF mirrorless system is not very valuable if you don't use FE lenses.  But the 55 is the only remotely interesting lens for that system right now...which is why I don't have one.

Lenses / Re: First Image of the EF 100-400 f/4.5-5.6L IS II Lens

Second  look (who am I kidding), after several looks I noticed there are no focal length markings, which by reference to 70-200 and 70-300 layout should be visible wrapping over the top.  Excitement fading  :'(

It is probably racked all the way around to the short focal length setting and the last mark is top/center in that position and not visible from this particular viewing side.

Agreed. If you look at the comparison picture from ahsanford on page 4 of this thread, the top view of the 70-300 shows that the numbers go down the side of the lens that we do not see in this leaked 100-400 image (when zoomed all the way out).

EOS Bodies / Re: Canon EOS 100D Detailed Specs Appear

Here is the "EOS-b" (placeholder name? EOS-"baby"?) page at Best Buy:
http://www.bestbuy.com/site/Canon+-+EOS-b+18.0-Megapixel+DSLR+Camera+with+EF-S+18-55mm+Zoom+Lens/8153056.p;jsessionid=FBE3200F8A85AF839C4B49F9F8AA93AD.bbolsp-app03-131?id=1218865165970&skuId=8153056&st=8575B003&cp=1&lp=1

Only thing remotely interesting except for its size: "Hybrid CMOS AF II" which "offers a widened focusing area for enhanced speed and accuracy"

Dimensions for comparison:

EOS-M: 4.29 x 2.6 x 1.26
EOS-b: 4.6 x 3.6 x 2.7
T3/1100D: 5.12 x 3.94 x 3.07
T4i/650D: 5.24 x 3.94 x 3.11
6D: 5.71 x 4.37 x 2.8

I'm trying to figure out what would happen if 0.34" were cut off of the T3/T4i and still maintain compatibility with all possible EF lenses.  Maybe no protruding Canon bulge in the front and therefore not as tall of a flash?

EOS Bodies - For Stills / Re: 5D Mark III Frustrated Focusing problem

I assume you are all referring to Bryan Peterson's Understanding Exposure?

i.e. http://www.amazon.com/Understanding-Exposure-3rd-Edition-Photographs/dp/0817439390/ref=sr_1_1?ie=UTF8&qid=1355123291&sr=8-1&keywords=perfect+exposure+bryan+peterson

It does seem to be the defacto standard for beginning photographers.  As an experienced photographer, I found some things quite oversimplified and some things he said that don't matter really do matter in cameras like the 5D Mark III, if you're going for maximum quality (like choosing f/22 apertures).  Also, it won't tell you how to use the AF system of the 5D3, you'll want to read Canon's http://learn.usa.canon.com/resources/articles/2012/1dx_guidebook.shtml.  You'll also want to search around for "5D Mark III af tutorial" on Google for more information.

All that said, you really should pick up a copy of Understanding Exposure and read it.

EOS Bodies / Re: Asking for 5D III firmware improvements
« on: December 03, 2012, 02:49:05 PM »
You can submit emails to Canon technical support with your requests and they will be read.  You will get a polite email saying your requests will be considered and/or forwarded to the appropriate people.  Here's to hoping they actually follow through with that...

5D Mark III email support:
http://usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digital_slr_cameras/eos_5d_mark_iii/form_display/support_by_kb_email

Generic support:
http://usa.canon.com/cusa/support/consumer

I've asked for:
1) Illuminated focus points
2) f/8 AF (they have promised this now)
3) Old zoom functionality in addition to new (I still hate the slow wheel zoom, but love the instant zoom)
4) Allow "Flash sync speed in AV mode" in "My Menu"...5D2 and 7D have this
5) More minimum shutter speed options
6) EV with auto-ISO
7) Built-in intervalometer functionality
8) Clean HDMI out (they have promised this now)
9) 1080p 60fps
10) Better dynamic range in future sensors

Regarding AF point and exposure linking, I too really wish the feature was available on the 5D3.  I posted about this a few weeks ago, so I'll copy it again here.

On the 5D3, the density of the focus points versus the density of the metering grid does not match well, so I don't think that this is a likely 5D3 feature.  The 5D3 and 7D share the same 63-zone, 9x7 grid.  On the 7D (which has AF point-linked exposure), the focus points directly matched up with the exposure metering region, as can be seen in this graphic from the-digital-picture.com 7D review:



So AF-linked exposure was a no-brainer on the 7D.  Not so on the 5D3.  However, on the 1DX, the metering grid is now 4x more dense (252 zones or 18x14), plus it has the 100K pixel RGB metering sensor, so it can match up the regions and pixels closest to the AF point with much more precision.

EOS Bodies / Re: Canon EOS 5D Mark III Blinking Red AF Point Information
« on: November 15, 2012, 03:25:32 PM »
I'd rather have metering linked to AF point, than a red blinking one anyway.

And I shoot most frequently in very dark circumstances, usually in AI Servo... I've just gotten used to it.  If I don't know where the AF point is, I just move it back and forth (which lights it up a bit).  Thumb is always on the joystick anyway.

The metering at the center, regardless of AF point is what really kills me

EOS Bodies / Re: DxOMark Sensor Performance: Nikon vs. Canon

I encourage everyone to let Canon know of your disappointment with their recent sensor performance (compared to the competition).  http://usa.canon.com/cusa/support/consumer
