Hi all, I have searched previous posts & only a couple touch on this product. I am fairly new to this interest but the more I do it the more I want to do it. Like anything I do I am drawn to the entry level, I'm not sure if I am doing myself any favors by doing this. ATM I am shooting cricket & AFL sports using a EF-S 55-250 1:4-5.6 IS STM. I find myself doing some heavy cropping to get full frame photos. I haven't looked through a 400 so I'm not sure what I'll get. Our grounds are approx 70 meters to the middle but I'd like to shot a tad further if I could. So once again I have been drawn towards the entry level 400 lens, is it the one for my requirements? Will I kick myself a month after getting it? Any advice would be appreciated.

BTW, is the MKll the same as this one I have supplied a link for?
