I love riding my horses and I love taking photos. So here's the thing. Over time, somehow or another, my thumb joints have become arthritic. Not too bad on the right hand, very painful on the left. Holding the reins, even lightly, requires use of the thumb. Holding a camera in my left hand while shooting with my right also requires the thumb. Did you know, if you're right handed, you use your left thumb for so many things? Opening pickle jars because you have to hold the jar to open it. Worse yet, try opening a container of Talenti gelato! See my point?
I like my Nikon D7000 but it's heavy with the 28-300mm lens, which is what I mostly use. I don't know what it weighs but I can tell you, when I go out and shoot a couple hundred photos, I definitely feel it. That is primarily why I'm looking at smaller cameras such as the a6000 I mentioned. I realize it's a whole new system to learn, and I also understand from the countless reviews I've read and watched, Sony doesn't have a friendly system. Sony does offer a great product with well thought out features. Very fast auto focusing, 11 frames per second shooting, and many more. The more reviews I watch on YouTube, the more interested I become.
My thumb hurts and I wear a support on my left hand almost all the time. But I am not giving up my hobbies. Or Talenti.
