So, what will a 7DII be like? Are these hints of a probable change towards FF or aps-h?

7DII would bever be FF. wildlife & sports photographers would go crazy :P

That 1.6X Extension for Free is too good to have available.   I see the 7DII likely to benefit from the work on High MP sensors.  Low Noise, higher FPS (maybe 12 as crop), great AF.  With that, it maintains a great pairing with the FF's for those who need a backup or need the reach with the same lens bag.

Thank-you Canon.  It makes my 7D and 5D Mark III all that much more a great pair.

I don't understand how a jump from 15 to 26 can be done with a firmware update either. Good question.

A friend and I brainstormed a few possibilities:
  • They had previously used the available RAM as a simple linear buffer, but changed their algorithm to use it as a circular buffer, allowing more images to be taken after the first was written to the card.
  • There was already a circular buffer, but the write order was optimized.
  • A redundant write verification step may have been disabled.
  • A delay that only became evident when the camera was used with higher-speed cards than were available at launch may have been discovered and eliminated.  (If you need a very fast card to get 26; otherwise, it's not this one.)
  • Someone did something really boneheaded in the original coding and it slowed everything down.

Good thoughts. 

I have to believe they already use Circular Buffers, but they may not have been very good at it.  This brings the other elements into play.  At the time they may have prioritized other tasks thinking they had the time; or yes, it could have been crappy programming.  The hack guys may have a better opinion of the quality of Canon's embedded programming.  It could also be an improvement in their proprietary OS that gave them more time/space headroom.

I almost forgive you canon for the 5D3 but if you can do this with the 7D, you could surely do a wicked firmware update for the 5D3. (60fps at 1080P would be nice.)

I have to believe this round is a derivative of the work done for the 5D Mark III.   Sounds like the same team.  But yes, hopefully they can get back to 5D3 upgrades; or maybe they'll be tasked with the high MP camera.

Lenses / Re: Recommendation for landscape lens on 5DMk111.
« on: June 04, 2012, 04:13:58 AM »
Pls recommend a suitable lens for landscape photography. Money is not an obstacle.
I'd suggest Zeiss Distagon T* 21mm f/2.8 ZF.

I second that. Zeiss 21mm.  Wonderful edge-to-edge sharpness, color rendition.  Magical.

But I will also note Kernuak's answer...  my 70-200 IS USM II rocks for many other landscape situations.  Strangely, I dont use the middle ground too much.

The TSE's are also nice for their purpose.

Got a Zeiss 21mm and I do not miss the AF at all.

Keep in mind though that this is wide and mostly used for landscapes and other events where I have a second or two to focus in.  The Canon Focus-Assist gives you an Auto-Focus confirmation - the only thing different is that you are the "motor".   I can see it being an issue on longer lenses or action/sports shot. 

For the wide, the edge-to-edge sharpness, microcontrast, and color rendition easily out-performs the Canons.  For me, its even worth being a prime instead of a zoom for the quality shots I get.

No regrets.

^this.   Looking back at the history of photos since WWII, yes - you see a LOT of huge DOF photography.  But those were also times where everyone on the planet didn't have a P-n-S camera in their pocket.  People hire a photographer to capture an image in a way that they can't.  (with the exception being photojournalism, where the qualities of a picture are less important than the content)   These days, almost anyone can capture a shot with huge DOF.  And until they figure out a way to get an f/1.4 lens with amazing IQ on an iPhone, I think that shallow DOF, buttery bokeh look is going to be what continues to give our services a perceived sense of value.

I and I know a many others are playing with focus-stacking.  Used effectively, its another way to get those impossible to capture shots with a P&S or camera phone.  And totally opposite of the dreamy bokehs.  My other sinful obsession is edge-to-edge sharp wides.

Focus stack when wide open means that you get the creamy bg blur with only the subject focal plane in focus

You can do it that way if you choose not to provide a background shot in-focus.

I mean numerous shots at different focus planes assembled together with software so that you are sharp near field to far.

On getting a FF (5D Mark III) and looking for a replacement to my EF-S 10-22, I have become a Zeiss convert with the Zeiss 21mm.   

The 16-35 just disappointed on the edge.  The TS-E 17 is likely a good Canon choice and may be on my shopping list.  14 not so much for that price.   So while the Zeiss 21mm is MF, turning for focus-assist is quite fast and the shots - amazing.  And I dont really miss the zoom.  When I need something wider, I'll look at the Zeiss 15mm.

If it works faster than fifty monks working on parchment, I guess I am happy.

Patiently waiting for fourth generation chips so Adobe can cripple my workflow again.

Serious memory pig. 

Interesting to hear about the memory usage on a well-built out system.  I got an older Alienware m9750 and LR 4 RC 2 runs like crap.  Lots of hard drive thrashing.  I guess upgrading isnt going to help much.

As a long time software developer, I got a few theories about whats happening and none of them good. 

Recommend Adobe give us 5Dm3 and D800 support on LR 3 to cover us; then release a LR 5 when its good and ready.

You might do HDR if you are capturing landscape as well - your mileage will vary. Actually its more of a Photoshop composite or maybe ND Grads

But back to filters - OPTCorp in Oceanside CA may be able to ship raw 250mm x 250mm sq sheets of Baader Astro at this late date - but its really late.  Truth is, the primary vendors have been slammed since April.   If you dont have the supplies now, its going to be tough unless you catch a break.

But if you do have film, there are plenty of instructions out there on how to make foam-core based cap filters.  I took an actually easier approach and built a LEE Filter form factor frame out of 1/32" model airplane plywood material with the film held with double stick inside.  I thought I needed some glue as well, but the double stick holds well enough for the purpose, and if I need to change out the film (its fragile!) I can just open it up and replace.  The LEE filter holds that assemble well, and I have at least 1/32" inch of wiggle room in the slot.

Circular ND's may work.  I got a 10-stop ND 3.0 B+W I may try for a second camera.  But any turning could throw your focus or composition off (and once that type of filter is on, you can not see through it).  And ND is not good enough for direct viewing - it does not block IR and UV.    The Baader and other films are at the ND 5 level (100,000 times if my math is right) and do block IR and UV, but you cannot see through them with a naked eye.  In fact Baader is somewhat reflective.  Makes a great mirror!

Also if you have dont have the software, get The Photographer's Ephermeris.  It free on PC (and likely Mac), with a small charge for iPhone and Android.  The software tells you all the geometry of the sun and moon over time and location.  Its required reference for anyone shooting sun and moon critical photos.

Use caution and common sense.  I'll be out in the southwest somewhere

Oh yeah, you'll have about 3.5 - 4 minutes to figure it all out.  Its kinda like shooting at Upper Antelope Canyon where I'll be on Friday.  :)

I have a 3-yr damage warranty through Mack when purchased my 7D.  As it turned out, I had a tripod accident and blew out the back CF card area.  Ok, it paid for itself but took 5 weeks to fix.

I recently purchased into the Canon Professional Services (CPS) program at Gold Level.  For a significant repair to my 70-200 f/2.8 IS USM II (same accident), I paid around $300 for "Major Repair" + parts at discount and got the lens back in one working day (sent Thursday, arrived Friday, sent back to me on Monday via FedEx).   This for $100 / year CPS Gold and there are more benefits than that - event onsite service, clean certs, swag, borrows.

So for the 5D mark III I recently purchased, I think that is the better way to go - in fact I may upgrade to the Platinum program soon - more expensive but so is my gear and I get significant discount on repairs.  And I get my gear back with very little down time.

EOS Bodies / Re: Canon fixed 5DIII light leak with tape
« on: May 02, 2012, 02:01:48 PM »
(Plus, I'm pretty sure that Canon Service can work on things inside the camera without messing up the imaging sensor, I mean, things do go wrong in there, shutter failure, etc., and Canon can fix them, right?)

As much as I loved using CPS repair to fix a "bump" on my 70-200 f/2.8 IS USM II, I did notice a few more dust specs inside the lens (when looking through it unmounted) after they opened it up.  Not enough to ever care, but still, not fully dust free.  It happens. 

As for the issue - yeah, its a non-issue.  I dont shoot in dark closets and only maybe if I am shooting the Milky Way at 12,000 ft 100 miles from any city would I ever have to compensate, and I usually AEB anyway.  Exposure Meter only folks!

Tape.  You should see the stuff I work with :)

I am sure somewhere there is a new inventory item on the Canon Repair Supply System -
(1) Roll 20' of Light Absorbing Adhesive Blocker - $100.

I got the Zeiss 21mm f/2.8 recently -  amazing, sharp, beautiful color, "3D".
With my 5D mark III - Wow!

I want to go out and shoot just so I can play with that lens.

Keep in mind Zeiss is for Full Frame.  Its way too much price for Crop if you are not using that awesome sharp edge.  Though I may use my 21mm sometime as a "35" on my 7D when needed.

Yes it is manual focus but the camera's Focus Assist beep/flash confirms you are are on target.  I actually love that - I can set my focus on what I want in the frame, then frame it up without AF messing it up.   Yes, you can switch the AF point or switch to MF, but its just so pure with the Zeiss.

My lens strategy - Canon "L" on the long (got the 70-200 f/2.8 IS USM II for starters - want the 100 Macro and 400 DO).  And Zeiss on the wide end (the 15 and 35 are next).  And a mix in the middle (the new 24-70 II should be phenomenal, and the 85 is going to be a debate of sharp/microcontrast vs aperture/AF).

Keep in mind you can buy Zeiss in ZF or ZF.2 as a Nikon native F and convert to Canon EF-mount if you are thinking playing both sides of the line.  As much as the D800 is interesting to me, I have confidence Canon will match or surpass the resolution in a year so I am sticking with Zeiss ZE and keeping it simple.

For crop, the EF-S 10-22.

But now that I got the full frame 5D mark III and my 7D goes to backup/long mode, I had to find a new wide.
For Canon, the 17-40 and 16-35's became non-starters with their lousy edge; the 14 was interesting; but only the TS-E 17 was of practical interest.

I went with the Zeiss 21mm - edge to edge sharp, magical color, and very wide for most situations.  A Zeiss 15mm comes later.  Its Manual Focus but Focus Assist does works great for situations where you would use ultra-wide on a FF.  And for a crop, its essentially a 35mm (33).

The 10-22 is likely up for sale soon.  Its like an old putter - love it, but I have a much better tool now.

Yeah really,

 I use the top LCD frequently.

 Anyway, went outside in Phoenix AZ around 3:00 PM, no issue.

 I suppose in the most light-tight situation, lens cap on, covered eyepiece, etc, maybe the LED could be a faint light source.

Someone mentioned tripod placement - yes I would agree.  Even slight changes of aim during a test like this may change the metering.
