I know that this is a beta test...but I am actually selling this lens on eBay (not as an auction item..just sale) and will offer it here at a discount and purchase by PayPal ONLY. Paypal offers a level of security in an online transaction.  If you are interested I can also point you to my eBay page and you can see that I have an excellent history as a seller and as a buyer there, i.e. I have great internet credentials for buying and selling.   

This sale is for:
Zeiss Distagon 21mm f/2.8 T* ZE lens for Canon EF
Factory Box and all paperwork that shipped with the lens.
Zeiss Factory Metal Lens Hood
Front Lens Cap
Rear Lens Cap

Price: $1459.00
Shipping: $16.99

This is an excellent copy of the incredible Zeiss 21mm.
I bought the lens new and was the only owner. I purchased this lens in the USA from a reputable Zeiss Dealer. The lens was used and stored with great care.
The lens is virtually spotless. There are no marks on the front or rear element.
(See Photos)
The front element was behind a protective filter for the entire time that I owned the lens and is in pristine condition. The lens is clean with no spots or fungus.
The lens was used very lightly. It is an extremely sharp copy.
If you are into incredibly clean WA images with excellent contrast this is the lens for you.
The lens cap has a few scratches on it (see last photo), but that is about it for flaws here.

Any questions please contact me via the forum message board  and I will do the best I can to answer them.

Lenses / Zeiss 15mm f/2.8 vs. Canon 17mm T-E f/4.0
« on: March 27, 2013, 01:58:52 PM »
Here is my dilemma. I am a not an architectural photographer does come up.
I am not shooting northern I do not definitely need the 2.8, but......(LOL!)
The filter thing is not going to sway me..what is available at 95mm anyway?????  :-)
I shoot a lot of set up shots inside with models and props. I do shoot buildings... Occasionally tabletop product...but not shooting professionally any more....just what I like, when I like.
... it could be nice to shoot some handheld shots at times in low light. (I know that is a crap shoot).
Both of these lenses are awesome...and I am just wondering if anyone has used both and could give me
some insight as to sway me one way or the other. I have to is a wonderful problem to have I am enjoying the ponder....
I definitely want to order one or the other in the next week or two....
Any thoughts?

Lenses / 85mm f/1.2L II plus Canon 12mm Extension Tube II Questions
« on: January 11, 2013, 09:01:47 AM »
As many of you may know...The 85 L II is a special lens...but not the closest focusing lens out there. I find that, sometimes to get in tight I am using a (3rd-party) 12mm extension tube...but I am having some issues with this set-up on my 5DIII... (BTW my copy of the lens is spot-on with AF accuracy,i.e. AF micro adjustment is zero.).

1. When I use my 3rd party extension tube...I find that I have to set the AF Micro Adjustment to +20.
    Does anyone using this set-up with the Canon 12mm Extension Tube II have this much variation in AF?
2. When I use my set-up with the 3rd-party tube, in the AF Micro Adjustment Menu my 5DIII recognizes my set-up as           
    "only" the 85mm lens (not lens plus tube)...and therefore each time I use this set-up I have to manually enter the
     AF Micro Adjustment and then set the MA back to zero or it will throw off my AF the next time I use the 85mm   
     without the ext tube.
     My 2nd question is: If I use the 85mm with the Canon 12mm Extension Tube II does the AF Micro adjustment
     menu on my 5D III recognize this set-up as 85mm PLUS 12mm Ext. Tube and keep it separate from the AF Micro
     Adjustment for the 85mm by itself? (i.e. does the AF Micro Adjustment Menu treat this situation the same as it
     does when I use a Canon Tele Extender on a Canon Lens?)

EOS Bodies - For Stills / Canon 5DIII and Media Cards...
« on: January 04, 2013, 08:19:43 AM »
I know that this is an old discussion topic...but I just am trying to clarify things for my (old) brain.
Regarding how the 5DIII records to to the two different card types, my readings and my own findings with my
camera tell me that:
1. If I write to the CF Card ONLY  the write speed will be native to that card (with or without an SD card in the camera). i.e. a 600X card will record at or about 45MB/sec.
2. If I write to the SD Card ONLY the camera can only write up to 20MB/sec regardless as to the write-speed of the SD card that I put in the card slot. i.e. If I put a 600x SD card in the slot with 45MB/sec rated speed, the Camera will only be able to write to that card at 20MB/sec.
3. If I have a CF card and an SD card in each slot, both rated at 45MB/sec and set the camera to write to both cards simultaneously, in the same image type to each card (i.e. RAW, Jpeg, etc.),  when I record an image, both cards will be written to at the slower, 20MB sec rate.
4. If I set the camera to write to both cards with different imaged types (i.e. write RAW to the CF and Jpeg to the SD, or visca-versa the writing will take a longer time than if the camera was set to write the same type of image to each card as in #3 above.
What is the fastest CF card that the camera can write to at the cards native write speed? i.e. how fast can the camera write to a CF card?
Any input to confirm 1-4 above or to increase my understanding of my camera would be welcome...I think I have it correct..but I could be wrong.

Just saw this listing on Canon Watch
Does anyone know of any info or reviews about this lens.....Looks intriguing to me!
I would like to know if the lens is at least connected to the CPU on a Canon you get focus confirmation. It is not definitely apparent in the stats...only for the Nikon does Voigtlander specify that.

Lenses / Canon 24-70mm f/2.8 II Shipping Date?
« on: June 09, 2012, 08:55:18 AM »
Has anyone heard any new information for possible ship dates for the new lens??? I have not heard anything lately and was wondering if the ship date is still in July sometime for the USA?

Lenses / Tamron 24-70 f/2.8 VC Available for Preorder
« on: April 05, 2012, 01:15:33 PM »
Anyone seen any reviews of this lens???? The only reason I am looking into it...( I own no Tamron products) because of the delay of the CAnon 24-70 f/2.8 II.....(which, truly I know I will wait for...LOL!)...but I just wanted to see what reviewers thought of the Tamron lens...I am guessing the usual caveats....I doubt it will give the new Canon a run for it's money in the IQ dept., which is all that really matters to me.

EOS Bodies - For Stills / 5D Mark III AEB/HDR Question????
« on: April 04, 2012, 11:43:33 AM »
OK....I shoot a lot of HDR with my 5D MarkII.
I may be insane..but I have read on a number of blogs that with the 5D Mark III you can bracket up to SEVEN images (still not enough in my world..and my little MFT Panasonics have done that for years now), automatically.
I think I may have read bad information.

Can anyone tell me if I am incorrect about the 7-shot bracketing information? (I would consider buying the MK III just for the increase bracketing alone.   I just downloaded the user manual for the 5D Mark III and checked in both the HDR section of the manual and the AEB section on the manual. Both sections say that you can STILL only bracket THREE photos??? Is this true? It is 2012. This is a $3500 camera body. It can only bracket 3 images without touching and resetting the camera?  Someone PLEASE tell me I am mistaken... LOL!!! 

Also. currently with my 5D Mark II...I use a Promote Unit with two cords attached to camera (very cumbersome, slow, non-fluid way to work, no doubt). Have to load in manual exposure information to the Promote Unit and can bracket all I want without touching the camera...EXCEPT if the exposure is over 30sec. Then I have to adjust the camera to bulb in the middle of the bracket, something I would love to avoid.   Does the 5D Mark III still not allow you to bracket past 30 secs?

I know this is sniggly info that I need...but I would love to have a high rez, full-frame camera that can shoot a wide range of brackets automatically. I believe the Nikons have no problem with this ...but I could be wrong.
Thanks to anyone who can give me solid info regarding this situation!!!!!

This HDR AEB chart on the web states that the 5DMarkIII can bracket 3,5, or 7 frames (shots?).
