So, I'll be going to Europe this summer, and I'm having a difficult time deciding what to take with me, and what to buy. Currently I have a Nikon D40x, the kit lens and a Nikkor 105VR. I don't intend on taking the 105VR, and my kit lens is saying its goodbyes, so I'll need a new lens. Taking into account I might have $800-900 to spend, these are the option I've contemplated so far: 1- Keep the D40x, buy a Tamron 17-50 f/2.8 VC and a backpack. The Tamron is $625 and the backpack is around $80-90. Or I could buy the older Tamron for $450, without VC. 2- Sell my D40x with the 18-55 for around $300-350, and buy a Nikon D90 with the 18-105 for $1,000. And also buy the backpack for $80-90. What do you guys recommend?
