Which 18-200mm lens for a nikon d40x?
hi,
im currently doing A level photography, and i have a Nikon D40x (not my choice.. would have gone for something better)
i have both a 18-55mm lens and a 55-200mm lens
but i find it annoying having to swap lenses, i was wondering by how much the quality decreses if i were to buy a Tamron lens not a nikkor as being a student i dont really have the money for a £450-£500 nikkor one.
i was also wondering if it actually is worth buying a 18-200mm lens when i have this range over 2 lenses?
thanks 
I’d say it all depends, if picture quality is not as important as convenience then yes, get the tamron. If you want to find a compromise go for nikon’s 18-105, load of range, good quality and quite affordable. Oh, and actually using that shift key on your keyboard makes your post readable and makes you look less like you’re intellectually challenged.
