Chinese manufacturer TTArtisan has launched a 500mm f/6.3 supertelephoto for the RF mount and others. The lens is manual focus, but looks to have good optical performance for certain types of photography. This is not a mirror lens, which is the usual design for inexpensive supertelephoto lenses.
The best part? The TTArtisan 500mm f/6.3 comes in at only $329 USD.
This design is for full-frame, but is manual focus. The optical design is 8 elements in 5 groups including 2 extra-low dispersion elements.
If we go by the sample gallery provided by TTArtisan, they see it as an astrophotography option on a budget. The optical performance looks really nice, especially considering the price. For a backyard birder with a nice perch set up, the manual focus likely won’t be much of an issue. It would also be easier to get some background separation over the f/11 Canon supertelephoto lenses.
The bokeh looks a bit busy in the bird sample photos provided, but we think it could be better with a better planned backdrop.
