I use the Canon 70-200L F/4 on my A7III which works fine, tracking not so much.Thanks NewBeetle.
The images look very good !
I am hoping to buy a A7iii in the near future and my EF canon fit lenses will be utilised on the Sony. I am hoping to buy a native 24-70 f4 lens hopefully with OSS, and perhaps another native E mount. Other than that all other lens I will hope to use on the A7iii will be canon EF fit.
Using mine with my 80D and its really good I have used the Sigma dock and Focal Reiken software to finetune the lens and have been able to test alongside my friends 100-400 MK2 and the Siggy does not let itself down on picture quality. The Canon is better overall in focus speed, contrast but the Siggy is very good for the price you pay if you are prepared to put a bit of time in tweaking the lensHow are people finding this lens on the canon APS-C fit, especially at 600mm?
My experience so far (Canon mount, 7D and 5D4):I had one of these for my birthday 2 years ago and it has just sat in the cupboard unfortunately. I was just to busy with work then. But from now on I will be taking a few days a week off, getting to old for full time graft these days. LOL
Going to start using it shortly for some bird photography. Do you guys who have owned one for a while have any tips for me when using please. Will be attached to a 70D
My experience so far (Canon mount, 7D and 5D4):
Get the dock and update the firmware, mine was distinctly average brand new out of the box
Have a play with the custom modes, there are a number of good ideas in the earlier part of this message thread regarding settings
Don't expect too much detail with big crops at 600mm
It's pretty sharp at 550mm f8
It needs good light for best results (true of any kit I know, but this particularly requires it)
Shooting my birdfeeder from the house (20yards) is "ok"
Birdfeeder at 20 feet is much sharper so despite the long reach the closer you can get the better
That's all I can think of for now, hope it helps.
I can't comment on what it's like compared with the canon 100-400, but used my lens for just over 3 years now, across the areas you mention and I have never regretted having it. It does get heavy, but I have a lot of weakness and strength in my right side. From the reviews of the 100/400 I have watched, I recall them doing a pretty good job Dustin Abbot's reviews are worth a watch if you haven't seen them.Sort-of tempted by one of these, or the 100-400mm sigma/tamrons instead of saving for the Canon 100-400mm Mark 2. Has anyone here switched from the Canon to the sigma, and what are your thoughts if so?
Mostly interested in portability, image stabilisation, build in poor weather. It'll be an all purpose long lens for me, for some wildlife but largely landscape/seascape and detail shots.
Edit: currently use a 6d and, for wildlife, will likely go for a 7d mark 1. Cheap and fast!
