<p>Please can you assist me in finding the suitable adapted for my lens, I'm having difficulties.<br /> I recently purchased an Auto Tamron 35mm f/1:2.8 lens (please find attached pictures), and I have a Nikon D3300.<br /> I bought the wrong adapted and I got told that "the lens looks like modified or built in Topcon Exakta mount (the stoppers are like Exakta mount)" and would need a Exacta-Nikon adapter. Is this correct, or would you recommend something else?</p>
