I’ve owned the Canon 70-200 f/2.8 for years and loved it. Since the switch to Sony I’ve been missing a good long lens. This guy fills the void in my camera kit with superior quality in a more compact and lightweight format. The weight of this lens in my hand feels perfectly balanced with the a7 body. It’s great for shooting the aquatic wildlife that surrounds us (if I’m fast enough to switch lenses) and I can easily capture videos and photos of the occasional wildlife we hope to see on land. I’ve only just begun to play with this lens but I am sure with the adventures ahead it will be a go-to lens for me.
If you want the top of the line version of this lens check out the G Master 70-200mm f/2.8 OSS.
I usually buy cameras from B&H, but I always check pricing on Amazon too:
