Nikon d3100/sony slt a33?

Any one dslr camera has manual focusing in video mode?
I don't have any one.

Sony alpha nex-5

The Pentax DSLRs with video have manual focus in video mode.

The Nikon D3100 can be manually or auto-focused in the video mode.

My guess is the A33 can be manually focused as well.

Canon EOS T1i, or T2i have manual focus on video.

Any dSLR that shoots video can be switched to manual focus, just like you can switch it to manual focus for still photography. The advantage of the Sony A33 and A55 is that when used with auto-focus it is FAST, much faster than other brands.
