Canon Extender EF 1.4x II Q&As

Good day dear fellows. Asking for advice... Photo for me is a hobby. have 7d mk1, 5d mk3, plus a bunch of lenses bought used on eBay. Recently I bought 100-400 mkII. 400mm feels short on FF (5dmk3), I have old 7d mk1, and 400mm on it feels about right. However, I cannot stand 7d binding, shadow noise, and high iso IQ. What do you think is the best way to move forward to get better reach for birdies? 1) Buy teleconverter 1.4x and use 5d mk3 + 1.4x & ef 100-400mkii? 2) buy 7d mk II (I hear...

Got myself recently a used Sigma 500mm F4.5 DG EX HSM to get some more reach, but i have some problems with extenders.  In earlier times it was often reported that this lens should only focus on 1D bodies using converters so i thought it should not have any problems with 5D mk3 that has same level AF system. But still it seems i have some problems locking down on AF spot. So at the moment i have tried with canon II extenders both 1.4X and 2X with and without taping the pins. It seems that the...

my 6d It works only with manual focus when I install TC 1.4 II. anyone had this problem? in BHPHOTO, they say it works, but my set does not work autofocus, only the manual.

Hi, I bought a Tamron 70-300mm f/4-5.6 SP VC Di towards the end of last year and I have been shooting water birds and small birds in general on my Canon EOS Rebel T3 (1100D) for quite some time. Recently, I rented the Canon 70-200mm F/4L IS and I must admit that it has been a pleasure to use it and the IQ is simply splendid in its focal range. I really feel like ditching my Tamron for it but then knowing that whenever I use these lenses, I always zoom out to the 200 or 300mm (Canon and Tamron...

Could anyone tell me which Canon camera bodies retain autofocus (without taping the pins) with a canon 1.4 teleconverter?

Hi. I just bought (almost) new Canon EF 100-400mm lens for bird photography for my 70D camera. As I already own an old Voigtlander Ultron 100-400mm I know that such reach (even with the camera's 1.6 crop factor) is sometimes not enough and I am not that much into photo-cropping in PP. I was reading many threads for last days - unfortunately all of them very outdated - about Canon's 100-400 L + TC setup (mostly with 5DmkIII or 1Ds) and read a lot about the problems with autofocus etc. My...

I am presently in the market for my first L lens. I am looking to get a telephoto lens that can get me to 400mm, and potentially beyond, for wildlife photography, mostly birds. I was convinced that the lens I was looking for was the 100-400mm f/4.5-5.6 because of the l-series build and image quality, and because of the IS. I have also heard good things about the focal range that the lens possesses "saving the day" for some, but I also have my concerns about the lens. I like to manually focus...
