Which SLR Camera will be best for Global Photo Exhibitions and Youtube?

I want to purchase an entry level super zoom SLR Camera having Full HD Video Recording facility for youtube video and it can shoot photos for international Levels. My main requirement in SLR Camera is 14 to 19 Mega pixels, Full HD Recording and 90X Digital zoom (I will purchase super zoom DX Lenses additional). My Budget is around Rs 35000/- for SLR Camera body (without Lenses). I have selected two models based on my video requirement for youtube. They are Nikon D5100 and Sony Alpha A37K.

Both SLR cameras have similar features. But I prefer Nikon D5100 for making HD Video for Youtube. Can you suggest me any other model which can be better option than Nikon D5100 for my requirements.

90x digital zoom? There's no such thing. Let's start with digital zoom: it's a marketing ploy to fool idiots. Optical zoom is the only meaningful zoom. Then there's 90x. If your widest angle was 18mm, the zoom would have to go to 1620mm. An impossible lens. An 18-300mm is the most zoom for a DSLR lens.

Perhaps the Nikon P520 will meet enough of your requirements to make you happy.

I will suggest you to check some best camera sites like canon, nikon and fujifilm they have the bunch of cameras in their list. Once you have a list of potential cameras in your budget range, you should visit a website like digital-cameras.findthebest.com to compare the cameras, and find the best from your list. Keep in mind that you do not necessarily have to buy the best camera in your budget and you could always compromise a little money on the body itself (as long as they both have the same sensor size) and get an additional lens instead.

Both (Nikon 5100 and Alpha A37K) have great live view systems, great image quality, and video performance is very decent.
The Alpha Alpha A37K is a more like a traditional DSLR, but uses a translucent mirror which enables the camera to permanently use phase detect AF, even during video, so it's very fast and with Hybrid CMOS Sensor and STM lens, Nikon 5100 rocks!
