Mark IV Pre-production Images

[Arthur Morris]

The four images I am posting here were created with a pre-production MIV bodies when I had a chance to test them two months ago.

The JPEGs that you see here were created from the large JPEGs that I created along with the RAW files. As I did not and do not have the DPP that supports MIV RAW images I could not convert them and was forced to go with the JPEGs.

This Sandwich Tern was photographed at Alafai Banks on a trip aboard the Hooptie Deux with BPN co-Founding Father James Shadle. (Note: other founders include Alfred and Fabs Forns, Blake Shadle, and Robert Amoruso. And to be technically correct, Robert O'Toole and Jim Neiger were with us at the start.)

Canon 800mm f/5.6 IS with the 1.4X II TC and a pre-production EOS-1D Mark IV. ISO 640: 1/1000 sec. at f/8 confirmed by histogram check. Central sensor AI Servo AF. Slight crop for COMP. No NR.

Canon 800mm f/5.6 IS with a pre-production EOS-1D Mark IV. ISO 250. Evaluative metering +1/3 stop: 1/1000 sec. at f/8.

Canon 400mm f/4 L DO lens handheld with a pre-production Mark IV body. ISO 1600. Evaluative metering +2 1/3 stops off the sky: 1/1250 sec. at f/5.6. No NR. Central sensor AI Servo AF.

Canon 400mm f/4 L DO lens handheld with a pre-production Mark IV body. ISO 12800: 1/8000 sec. at f/5.6. Photoshop NR on the BKGR and the gull's mouth. I screwed up the EXP with this image while experimenting. There were a few hot pixels that could have been recovered in DPP or in ACR.

Art, They look great, Did you have a chance to microadjust before using or was everything OK. I noticed my combo needs plus 5 to produce the sharpest image. Ron

[Arthur Morris]

These were out of the box.... No micro-adjustments.

[Morkel Erasmus]

looks very good. when are you getting your own bodies, Maestro?

[Arthur Morris]

Mork-man, Thanks for the reminder. :) I am calling Canon now in hopes of getting at least one before I leave for San Diego on Monday.

Hi Arthur,
Can you please post the ISO 12800 image without the NR. It would help compare the noise handling performance at different ISO levels. :)

[Peter Hawrylyshyn]

Artie -
Was there a reason you only used Central sensor AI Servo AF for the BIF images? Did you try other modes?
Did you use a tripod?

[Morkel Erasmus]

hope you get one in time...:)

It did not make it yesterday.... Today is my last chance. :confused:

As requested.

Most expert flight photographers (I do not include myself in that group) use and recommend the central sensor only (with or without expansion to surrounding points--depending on the camera body). Robert O'Toole (when he used Canon) was the only person I know who used 45-Point for flight all the time with great results and that was even true when he borrowed a MIII from me!

I think that I used 45-point in a few situations but without the DPP I cannot see the focusing points....

Yes to the tripod.

I eventually answered your FLA e-mails :); did you get my response?

Artie,
Those shots look great...especially for limited processing. Thanks for sharing the info....especially the higher ISO shots. That was what I was most curiious about.
