Picked up two lenses cheap on ebay for my D7100 - as my sigma 18-50 decided not to work with it I decided to get Nikon 18-70. focuses really fast and is quite a useful range and a bit faster than the kit lens. Still a budget lens but should do for now
Also go an old 80-200mm F4.5 N AI., Manual only but my word is it built like a tank and easy to use too. Paid £25 delivered for it, still a great lens and apparently was Nikons top pro zoom lens when it was made 40 years ago. Was in good condition too
Not had much of a chance to use them yet though, lockdown is supposed to ease a bit end of the week so maybe then.
