I read in last month’s issue that some of Nikon’s latest lenses are incompatible with older DSLRs. Which camera bodies are affected? Tony Kramer, via email
Jason says… The issue mostly affects AF-P lenses with pulse motor autofocus systems, and E-type lenses with electromagnetically controlled apertures. AF-P lenses are fully compatible with the D3300, D3400, D5500, D5600, D7500 and D500. They’ll also work with D5200, D5300, D7100, D7200, D750, D810, D5 and Df cameras, although a firmware update may be required. However, they’re completely incompatible with all older Nikon DSLRs, where focusing is impossible in both auto and manual modes.
E-type lenses lack the usual mechanical lever for controlling the aperture and rely on an electronic connection. This makes them incompatible with older DSLRs including the D40, D40x, D60, D70, D70s, D80, D90, D100, D200, D300, D300s, D3000 and D5000, as well as D1 series and D2 series cameras.
Lenses like the new Nikon AF-P 70-300mm f/4.5-5.6E ED VR with a pulse AF motor and electromagnetic diaphragm have two potential incompatibility issues
