The heck?  That can't be right... maybe just a different release schedule?

at least it's not a joke like the 60D; it looks likes a real XXD body
can you name those apparent differences? i cant tell. im serious. in my eyes, it actually looks somewhat small

I agree, look at photos of the 70D compared to the 60D/7D bodies - 70D looks pretty much identical to the 60D from what I can see.  Looks like they share the same bottom height and layout, profile, etc.

A weather-sealed 16-50mm f/4 IS sounds wonderful.  As does the 14-24mm f/2.8 - but what'll she cost? $3K?

On the 5DIII, silent shutter modes have a noticeably greater shutter lag and longer viewfinder blackout times versus non-silent modes.  Still, it's an invaluable feature, and the shutter lag/viewfinder blackout time penalties are not too significant.

Windows 8 Pro 64-bit
Intel 3770K CPU
Gigabyte GA-Z77X-UD5H motherboard
AMD Radeon 6970 2GB graphics
32GB DDR3 1866MHz RAM
256GB Samsung 840 Pro SSD
About 6TB worth of mirrored storage across several 7200RPM drives
More storage via NAS

Unsurprisingly, photoshop runs great.  My panos take far less time to process on this computer versus my old machine (having 32GB of RAM comes in handy - I've seen photoshop using 28GB+ a few times while stitching together 40+ frame panoramas).  For general image editing, you don't need nearly as much RAM as I put in my machine - but having more can't really hurt.  The only time I'm ever really waiting is when firing up the mechanical hard drive arrays - they take a second or two to spin up from idle.  I can't really complain about performance.

Interesting design, but it's a workstation - and if there was ever a use-application where the size of the box was not a primary concern, it's workstations.  All those custom parts means you can pretty much forget expandability.  No displayport or DVI, so you are pretty much limited to thunderbolt displays (or HDMI).  Performance sounds pretty great for the size.  Built-in bluetooth 4.0 and ac wifi is nice.  What'll it cost?  I assume unreasonable amounts of money.

Nice caddy shack  drop.  I have nothing in response but I appreciated it.

so where it's this in the packing order of the  Canon 70-200 is f2.8L mkii.  better,  worse,  our  just a different lens so the comparisons aren't really fair.

Well, judging from TDP's IQ charts for the IS II and the previous version of the sigma 120-300mm f/2.8 OS, the canon is way better (at any aperture) in the 70-119mm range, and sharper across the frame @ f/2.8 from 120-200mm, but it just doesn't compare at 201-300mm.  Throw a 1.4x III on the IS II and @280mm the canon is sharper from mid-frame into the corners @ f/4, but the sigma is sharper in the center.  And the sigma also does f/2.8 @ 300mm - so it's got that going for it, which is nice.

Honestly, I wouldn't be surprised if the v2 sigma has better IQ than the previous edition, if for no other reason than that it seems like sigma's finally taking quality control more seriously.

If this lens has no autofocus demons with Canon bodies (or at least none that can't be banished using the USB dock), they'll sell quite a few.  Sure, image quality of the previous version (optical formula is unchanged in the new version) wasn't perfection like the Canon IS II's, but it was good enough, and the price is a bit more down to earth than first party kit.

The weather-sealing is a nice add (about time, too).  On a related note, does anyone know if it require a filter to complete the sealing (because 105mm filters aren't cheap)?

Just to confirm - everything else is the same with the physical setup?  Remember that it's not just what's in front of the camera that matters - light entering through the VF also affects metering so if you're in a different position behind the camera, that can make a difference.  Try covering the VF during testing (a lens cap hung over the eyecup does the trick).

Since Live View metering is done using the image sensor rather than the metering sensor, might be good to see if the same phenomenon occurs in live view.

The change was directly related to physically moving the AF/MF switch on the lens - shutter speed on the secondary LCD updated instantly as I switched the AF/MF switch (I flipped the switch multiple times a second and shutter speed changed directly in time with each flip of the switch).  Viewfinder covered, ISO100, f/2.8 - additionally, this issue does not replicate in LV mode or any other metering mode besides evaluative metering.

Please can you check your camera, in AV Mode and Evaluative Metering, do not move, and switch the lens to manual and back again to Auto AF and please look at your metering value does it change?

It doesn't seem to change with a different lens :o

But does with the 24mm

Thanks for your time,


I have a 5DIII and 24LII (that exact combo happened to be sitting on my desk when I saw your post...), and can confirm the issue you noted - switching between AF and MF on the lens changed my metering value by 1/3rd of a stop (AF mode was giving me an exposure of 0.3" and MF gave me 1/5) - an odd little quirk, but I don't really consider it to be much of an issue.  I'm running the latest firmware if that makes any difference.

A foveon-style FF sensor in a canon body would be sweet.  Canon, dooo ittttttt.....

I'd still like an updated 100-400L, though, as a more portable option.

Same here - large aperture superteles are fun and all that, but most of time I want something that can fit in my usual camera bag and doesn't weigh me down too much.

Need some advice:

I am looking for an compact Camera or Mirrorless for climbing or high-altitude hiking.
  • smaller an lighter than SLR
  • focus on high image quality
  • normal AF speed (shutter lag <0,5s)
  • able to use an polarisation filter e.g.
  • wide angle preference
Price unter 1500€ inclusive wideangle lens

I aimed at the Sony Cyber-shot RX100, but there are very variying tests. (Dpreview gives not the best notes. Color foto (German magazine) says superb,...) Which test to trust?
The Fuji 100s or the X-1E?

Which model would you prefer?

I have an RX100, corners at wide angle are a weakness.  Otherwise I like it quite a bit - IQ is better than any other compact I've used, but not up to the standards of my 7D.  Being able to charge the battery via microUSB is an asset in the backcountry if battery life is a concern (although the RX100 already has pretty good battery life) - you could keep it charged w/ a small solar kit (I have one that works with the RX100 and weighs about 8oz).

How about the Nikon Coolpix A or Ricoh GR?  Fixed 28mm equivalent lens, APS-C sized sensors (no AA filters on either), very good IQ for the size/weight.

Also consider the Sigma Merrill DP1 - amazing low ISO IQ, but a bit heavier, slower AF, slow write speeds, slower in general, battery life isn't great, high ISO performance is crap.  But that low ISO IQ is amazing.

I think the Ricoh GR would probably be my top recommendation at the end of the day - cheaper than the Nikon, IQ just as good or better.

HDR - High Dynamic Range / Re: Post your HDR images:
« on: April 25, 2013, 06:20:21 PM »
I recently moved into a new apartment, here's an HDR panorama of one of the new bedrooms, shot with a 5DIII + 24L II.  I believe there were a total of 12 frames - 4 sets of 3 frames (-2.3, 0, +2.3) converted into 4 32-bit tiff files, then reprocessed in ACR and photomerged via PSCS6:

Very nice. Great use of HDR, not looking like something produced by Looney Tunes.

Thanks.  Although most of the credit should really go to the HDR processing method I used - creating 32-bit tiffs in Photoshop CS6 and then reprocessing them in ACR makes it very easy to create well-balanced, realistic looking HDRs.  Someone here posted B&H-produced tutorial of that functionality awhile back and it really streamlined my approach to HDRs.

Edit: So it was actually Adorama that made the tutorial I'm referring to, highly recommended viewing if you own a copy of CS6 - http://www.youtube.com/watch?v=-JT1b12BBHs#ws
