BIG LENS or BIG SUPER ZOOM ??

I have a chance to buy a Tamron 150-600 VC lens used at a good price ??but the NEW Nikon P900 will ship soon ??Birding & Wildlife is my goal,,have a Canon SX50HS and like it..the big lens would be used with Canon 50D & 40D,,, My hands are strong but getting old ( 73 ),,also have and like the Tamron 70-300 VC,,,but wife thinks i should get the P900what do you all think ??only can afford one ?? any imput would help??
Thanks Ron

Nikon P900
Pro: 83x (2000mm equivalent), which no DSLR can reach! And very light weight
Con: JPEG file with much small sensor

Tamron 150-600mm:
Pro: Yes, Definite wild life lens
Con: Heavier

If I'm 73, I'll most likely get a Nikon P900 for my Safari

Thanks Tan,,,,

if you're not trying to catch shots of things moving, the superzoom seems like a good choice...

Heya,

Depends on what you want the final media to look like.

The superzoom will not do well on moving things in low light. The smaller sensor will have more noise, less overall dynamic range and definition, and simply not be as sharp. It will, however, be light weight and small and easier to use for casual shooting if web media is your intended final media output of the work.

Personally, I'd rather have the 50D + Tamron 150-600. It's only 3lbs. Put it on a tripod.

Very best,

My Choice would be the Tamron, and a monopod to take the weight.

Thanks i am about to go 4 da Tammy,??i can always get the P900 later ??
