Lenses / Re: How many times did you return (L) lenses to get a good copy?

ps:  If anyone can tell me why it says Powershot G-15 below my name I would appreciate it.  Went to edit my profile but could not find that....

I have owned probably 30 different L series lenses, mostly super-telephotos (including three different 100-400s) over the past three decades.  I never do any tests and I have never returned a lens.  For the past few years I have been micro-adjusting all of my long lenses with the LensAlign.  I have done OK over the years with my bird photographs.  I think that it might have been Micheal Reichmann who said, most lenses are sharper than most photographers. 

I just checked.  He said, "Most lenses are better than most photographers.   In either case, I agree whole-heartedly.

Indeed - that's why the Magic Lantern devs always have to wait for the first firmware upgrade to get access to the code, they found no way to dump the current firmware out of the camera.


Guess that I will not be sending my 1DX to Canon for repair....

Should point out that Phil on BPN stated, "I have a Kenko 1.4X Teleplus Pro 300 sitting in my dry box for years."  It's been mentioned in a couple of places that the f/8 AF on the 1D X seems to work only with the newest DGX version of the Kenko 1.4x, not with the older DG version (therefore possibly not with the even older vanilla Pro 300 version). 

So, perhaps there's some hope...

Not really.  Folks with a 1DX with 1.06 who have just purchased the Kenko 1.4 are reporting a no-go--at least that is my best current understanding.  Also, on BPN, Martin Lord tested the Kenko 2X Teleplus Pro 300 with the 600 II; the results were dire--nowhere near sharp....

Well, I am confused about who said what   .

But when I went to the link it talked about the TC focusing with a Canon 2X or something like that.

What I know is based on the comments of several others both on my blog and on the BPN post here: http://www.birdphotographers.net/forums/showthread.php/102647-1DX-Canon-800mm-f-5-6L-IS-Kenko-Teleplus-PRO-300-DGX-1-4x-AF-Teleconverter (I believe...)

Agree. Not very nice at all.  I have written some folks at Canon for confirmation.... Will advise.

Maybe known, but anyway.

A Kenko 1.4 PRO 300 DG won't do the trick on my 7D with 400 5.6. I guess you need a DGX  .

Just had a look on the Kenko site. It should not be possible according to them. They state that:

"Most Canon EOS camera bodies are programmed to shut down auto focus if the calculated effective aperture for the lens and teleconverter is smaller than f/5.6, the Kenko Teleplus PRO 300 converters work the same way"

Childeric,  Not to be a pain but that is not exactly what you wrote. In fact, what you wrote is not at all what I wrote .

I don't understand the need to dial in -1 stop compensation?  Doesn't the light loss caused by the TC automatically result in a lower metered exposure?  I'm confused

It looks as if you nailed this one....

It seems that firmwares later than 1.02 disable to ability of the 1DX to AF at f/8 with the  Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter with all the accompanying benefits....

Does anyone know if it possible to save the firmware that is on the camera?
