Lenses / Re: New Wide Angle Zoom Discussion & Opinion
« on: August 15, 2012, 05:43:56 PM »
I own a 16-35mkII and it worked perfectly with the 1Dmk3 I had.

After I replaced the 1Dmk3 with a 5Dmk3 the 16-35mkII wasn't good enough anymore: the off-center unsharpness is just too visible. I bought the 17-40 which is a lot sharper (but obviously lacks the F/2.8).

I really like the 16/17 to 35/40mm focal range, so I'm really hoping they are going to release a sharp 16-35mm F2.8. The 14-24mm F2.8 sounds as a nice addition to the 24-70mm, but for the type of photography I'm doing I'd rather use a 16-35 + 70-200mm combo.

Just my 2 cents.

Mark.

You're the first person I've ever heard say the 17-40 is sharper than the 16-35 MkII.  I'm going to go further and say you outright had a defective copy of the 16-35 because every tester says the 16-35 is sharper and my own experiences have reflected that.

If I recall the charts correctly, the 16-35 is sharper, but has a fairly dramatic drop at the edges.  The 17-40 has less of a change from center to edge - so it the perception may be less pronounced.

That or yeah, crappy 16-35 copy.  But even then, I recall most of the sharpness is in the upper end of that lens - which can be handled by far better lenses.  A 14-24 or even a really good 16-24 would be preferable, since just about everyone has 24 on up.

The only way I even care about new Canon wides is if they finally become edge sharp.

Regarding the tail end of the article, when does the Zeiss 15mm finally make it to the channels?  I love my Zeiss 21mm (its become my landscape walk-around) and the 15mm would complete my needs at the wide.  Except for maybe a Canon TS-E 17mm or if I want to fisheye with the 8-15mm

But if Canon finally does get their sharpness at the level of some of their longer lenses... maybe I would consider.  But that would mean they care about more than wedding and sports.

Thank-you for the photos.

I have the Zeiss 21 - absolutely stellar - and thinking about the 35mm down the line.

EOS Bodies - For Stills / Re: Bought a 5D Mark iii Today (YAY)

Hey, I know exactly where that is in Vegas.  I was less than a mile away at my office off Bermuda. 

Congrats on the purchase.   Its a damn good camera.

This was certainly one of the upgrades I was hoping for as well (why wouldn't canon do this - it must be a fairly straight forward change?).

-----

Even if sounding a bit repetitive :-p ... magic lantern does this, too, it even calculates how many brackets you need on the fly - so shoot 10 or more pictures with 0,5 ev steps for exposure fusion, no problem there.


Yep, but no Magic Lantern for the 7D as noted above.  The Dual Digics are the complicating factor. 

I suppose that means no Magic Lantern for the 1DX as well - with 2 Digic 5+'s and a Digic 4.

 

51
5 or 7 AEB bracketing would sure be nice.. considering what else they are doing it should be a simple addition. i hope they dont leave that only to the 5dmkIII and above

Amen.   5 and 7 AEB is one of the most useable day-to-day improvements I have enjoyed with the 5D Mark III.  With the 7D, I need to take 3, then go into menu, shift it all, and take 3 more.  With the 5D Mark III, I can lay a -1 to +1 range on thirds.  Should not require any technology changes - just firmware.


52
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.

53
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.

Quote from: RLPhoto
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.

55
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.
