Thank you...honored at the compliment, but not a professional - just a hobbyist!
A majority of the shots are from my Sony H5, an 'ultrazoom' camera which has a 432mm telephoto, and I also used a 1.7x extender for alot of the far away shots, which gives me a 720mm. Four shots were taken with my newer
DSLR, a Sony A300, mostly with an 18-250 lens that gives me 375mm total zoom. I also have a massive 200-500 lens (total 750mm telephoto), but that's usually a bit much for lugging around Disney! I use it for wildlife and birding shots down here at home.
I have a Canon & a Pentax, and had Minolta & Nikon in the past - I'm not a brand snob...I go with what feels good and works good for me at the time. I don't think any of the top 8 brands make a bad camera nowadays, so I ignore the 'get a Canon', 'get a Sony', or 'get a Nikon', etc. Try them all, see which you like, learn to use it as well as you can, and the brand won't matter as much! I've had good results, like the features, ergonomics, and the image quality, and good reliability from Sony, which led me to stick with them the last few cameras.
I'm up there in December myself - Maybe I can tag along and snap a few shots for ya!
