Hopefully you'll be in luck as pretty recent Canon stopped support for this - was within the last year. This thread suggested an option - Midwest Camera Repair - Good luck and brilliant if you get ...

is it the f/4.0 - or the f/4.5 ?  If the latter, unlikely.....

The mark 1 is slightly shorter than the 400mm 5.6 prime in focal length - I briefly had both. 380 seems about where the mark 1 was. The new mark II is slightly shorter in focal length than 70-200 ...

Owned a 35mm f/2.0 IS for while and loved it apart from coma which is essentially non existent within APSC but really strong just outside the APSC crop on full frame - not just at extreme edges at ...

:-)

Hi Have owned both - like one earlier poster a recent and good copy of the mark 1. IQ differences in the centre I think can be seen, but not amazing different. So not a marked differences. Unless ...

Great sensor at ISO 400 upwards even by today's standards. Sold mine due to lack of joystick on the 5D series and AF not great other than the centre spot.

Ouch - that convinces me - the 75-300 at 300mm f/5.6 I could not use happily from past brief experience... but guess subjects and sought effects different with the 50 1.2. The 28 1.8, another lens ...

Hi As long as you stick to eact process, Ebay tends these days to side with the buyer. Just make sure you pack the lens really carefully and with insured tracked delivery to the seller. Be very ...

sure - but would still expect the 17-40 to compete with the even older 20-35..... 17-40's were used by pros and reviewed very favourably to the mark I and II 16-35s. Not the best but not this bad.....

Hi - sorry it looks like you have a defective lens - as long as everything is done correctly your end. The 17-40 will have soft edges at 17mm f/4 but should improve by 20mm f/5.6. It is not the ...

Brilliant  lens 100-400mm. Just my experience: (1) Add a TC in my view becomes "OK" - f/8 vs the f/6.3 in OP has in the 150-600 and in some cameras AF limitations. Build good too. IQ of 100-400 + TC vs ...

Tricky really - the sigma and tamron 150-600's are good - the only close canon equiv. the 100-400 II which I own is great but you lose the long end and whilst I think you'll gain some advantages ...

ouch - what's gone / going wrong with the 500 and how might it have happened?

Fully agree :-) and guess what I was trying to say - the downsizing to 22MP of the 5DS actually beating by a slight amount the 5Dmark III shows this nicely on the digital picture + what you see on ...

Never had a 1DX 2 but have experience with the 5D series (classic, 2, 3, SR) and various crops 20D,50D,7D1 and 7D2 - and yes I've usually also had too short lenses to fill the frame on APS-C - ...

I own the 500mm f/4 II and the 1.4 and 2X II extenders and used to own a 7D2 and still own a 100-400 II. I'd personally suggest 5D mark IV and the 1.4X TC with the 500mm I think in your situation. ...

The search tool and google are great in my opinion

No not with the lenses - suspect you will be fine AF'ing on the centre AF point on the 6D1 - as this AF point is excellent. Let us know how you get on with the outer points as they are not cross ...

No AF with the 6D1 unless you have a non reporting or electronically interfered with TC - and even then be careful with exposure and may need to AZ adjust.  (I used to have a kenko 2X DGX with my ...
