Hey guys, I'm having a bit of a dilemma, I'm trying to decide which way to go gear wise to accommodate my 70-200 2.8 l is ii. I am an enthusiast looking to move up to a ff, and shoot landscapes, portraits, and some sports(why I got the 70-200 and my extenders.)
Making lens choices having a Crop Sensor Body looking ahead to a FF Body is difficult. The 70-200 you have currently will have much shorter reach on a FF and therefore your dilemma will be different with a different body.
You have the cream of the crop zoom now, so you will want to find something comparable in your next selection. I would also recommend the 16-35 f2.8 II. On a crop sensor it provides a 24-55 zoom. This will give you the range, speed and image quality you are familiar with form your 70-200 f2.8 II.
If/when you move to a FF body, I suspect you will find yourself wanting a 24-70 and a 300 to gain back the range lost without the 1.6x crop factor.
