The Canon RF 70-200mm f4L IS USM is a compact telephoto zoom for the EOS R mirrorless system. It uses an extending barrel that makes it comfortably shorter and more transportable than the previous EF version. Announced in November 2020, it comes just over two years after the previous EF 70-200mm f4L IS II USM and costs roughly 50% more, albeit about one third less than the RF f2.8 model.
The new RF 70-200mm f4L model follows a similar strategy to the RF f2.8L, employing an extending barrel to become much shorter at the 70mm focal length. When both lenses are zoomed to 200mm, the new lens almost exactly matches the 176mm length of the fixed EF model, but when set to 70mm, the new RF model shrinks down to just 119mm long where a switch can also lock it in place. Weighing 695g, it’s almost 100g lighter too and works out roughly similar in size and weight to the RF 24-105mm f4L. Optical stabilisation provides five stops of compensation on bodies without IBIS, or up to 7.5 on bodies with IBIS. Dual Nano-USM motors take care of focusing and allow the RF model to focus much closer down to 0.6m versus 1m on the EF model, while also promising better quality at close range, although due to their optical designs the actual magnification at their closest distances is almost identical. The weather-sealed barrel is also 4mm wider and employs a larger 77mm filter thread, and as an L model is also supplied with a lens hood. In terms of quality, Canon promises similar or better than the previous EF Mark II model which bodes well.Check prices on the Canon RF 70-200mm f4L IS USM at B&H, Adorama or WEX!

That’s all I can say until I test a final production sample, but I hope to have my review ready by the time it goes on sale in early December.Check prices on the Canon RF 70-200mm f4L IS USM at B&H, Adorama or WEX!
