The current DX 55-300 isnt as well constructed, has a plastic mount, and to use it on the 1 System requires the additional FT-1 adaptor.. The 70-300 includes Nano coated, Super ED, Metal construction and doesnt require the FT-1.. I think the 2x price is justified. No? .. and comparing the FX 70-300, its around 590 + 200 (for FT-1) around 800.. so.. the actually price for the 70-300 1 system is 200s more.. If you already have this setup, then getting the new lens is pointless in my opinion.
But if you dont have the 70-300 and FT1.. it looks like a good deal.. and it has a tripod mount to boot.. I like this new offering.. but not the 10-30..
edited again.. tripod mount is optional accessory.. hmmm
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
