but if you're going to shoot birds, the DSLR s have better tracking and focus capabilities and better ISO performance than the mirrorless cams. (from what I hear and read)
Sony A6000 has 11 frames per second and 179 Focus Points the Nikon D5 a £5,200 camera still only has 153 points ...
An A6000 can go up to 25,600 again just as comparable as a DSLR
Another thing is, I believe that shots per battery charge is much lower with mirrorless... You can always buy extra batteries. Just another thing to consider.
Probably about 400 shots to a battery, Sony add (in some cameras) 2 batteries in the box so it can be negated just like a lot of us use a battery grip
I recently watched a video by Tony Northrup, he said that one issue with the Sony mirrorless was the start up time.
Hmm 1-2 seconds start up time, if he was really going to get shots the camera would be ready especially with wildlife
P.S im really not a fan of him
I am not a mirrorless expert by any stretch of the imagination, but DSLRs still have WAY more lenses to choose from, and I think that in itself makes them better for birds and other wildlife.
The Sony has a VERY good adaptor in the LA-EA3 from Sony to Canon Lenses so you have every single Canon lens available to you. It doesn't work the other way (Sony to Nikon) yet as Nikon uses a mechanical focus and that is harder to reverse engineer over Canon's electrical focus
Other points of interest:
Weight- I feel it when I have been lugging my D600 gripped with a 70-200 2.8 on it after a while.
Focus Peeking - Who doesnt want to be able to zoom into their image and make sure it is TACK sharp before you take the photo.
EVF - Why is DSLR's so backwards in still wanting to put prisms into the cameras where you can add an electronic viewfinder and see what changes you are making in the camera instead of having to look at the back of the camera. You get the exposure how you want it in the camera and shoot and shoot and shoot no need to worry if the lighting has changed as you will see it in the finder.
ALL Flashes work, be it Yongnuo, Nikon, Sony or Canon, on a Sony it just works
BUT the biggest one is price ... A6000 Body is £389, a D7200 is £569 ...
Just to finish I still LOVE my DSLR and my D600 but looking at what is in the Mirrorless ... the advantages are far outweighing the negatives at the moment for me ....
