Lenses / Tokina 16-28mm FX Focusing Issue with 5D3

« on: March 21, 2013, 12:11:17 AM »

I have had this lens for about a month and have been enjoying it. However, tonight I noticed when I went outside to take some shots that it didn't seem to be locking focus on the left hand side. Even if I placed an objected toward the left side of where I was aiming, making sure that the object was closer to the lens than anything on the right side of the view finder, it still seemed reluctant to grab focus toward the left.

I put my 5D3 in a different focusing mode, eight-point selection to the far left, and it managed to lock on okay then. However, once in awhile the camera would seem to do a "freeze lock" and even if I took my finger off the shutter, I could immediately press down again and take a picture without the lens regaining focus.

I tried to replicate this issue on my 5D2, but I can't seem to reproduce it. Everything seems to work normally.

When compared to my 24-105L on my 5D3, aiming directly at the edge of a table, the 24-105 picks up the table in a completely perfect focused line in the view finder. The Tokina 16-28 only picks up the right side of the edge of the table. Again, this doesn't seem to be an issue with the 5D2; the lens worked fine.

I have used FoCal to calibrate the lens on both the 5D2 and 5D3. My adjustments with the 5D3 were -11 for the wide end, and +3 for the telephoto end.



Do you guys think this is a calibration issue, or do you think I should return this copy of the lens and see if I can get another?

EOS Bodies - For Stills / Camera body lens mount removal

« on: February 21, 2013, 10:58:51 PM »

Does anyone know how to take the lens mount off a 5D2?

I have the four screws out, but the mount won't lift off. I'm assuming there might be a slight lip to the mount that's preventing its removal.

Lenses / Tokina AT-X 16-28mm F2.8 vs. Canon EF 17-40mm F4

« on: February 01, 2013, 12:59:11 PM »

I'm thinking about purchasing either one of these lenses. I have read reviews on both, and both have their advantages and disadvantages. I also did a search on this forum for information, but I am just seeing if anything has changed regarding the Tokina and if more people are using it now.

Does anyone have any experience or recommendations with purchasing either one of these lenses?

Software & Accessories / 5D Mark II with Magic Lantern + Reikan Focal lens adjustment software

« on: November 27, 2012, 01:11:03 AM »

I just installed magic lantern on my 5DII tonight (which is awesome, BTW) and I'm now wanting to use Reikan's Focal lens adjustment software.

My concerns are:

- Now that I have magic lantern installed, will it affect the operation of the Reikan Focal software?

- If I decide to remove Magic Lantern down the road and I have to reset my camera, will all my lens micro adjustments be gone until I reuse the software to get them back?


Thanks for everyone's time.

EOS Bodies - For Stills / 5D Mark II ~Help!~ order of metal shims over superimposed plate?

« on: October 25, 2012, 04:43:06 AM »

I disassembled my 5DII to get some dust out from behind the focusing screen and the superimposed indicating plate by the prism. There are two metal shims between the focusing screen and the SI indicating plate - one a gold colour and the other silver. 

When I took it a part I swore the gold shim came out first and was closest to the focusing screen, and the silver spring second and closest to the SI plate.

Now I am not too sure...

My questions are:

1) Does anyone know the correct order of them?, and

2) Does the order even matter as long as they are both there?

Hi Everyone,

I've been a lurker for some time here on Canon Rumors and I've finally decided to join and contribute to the forum. Here's some pictures I took with my 7D earlier this month of my beautiful city, Calgary.
