Refilling a Gap

I picked up another refurbished RF 50mm f/1.8 STM lens after having traded in my prior copy when I migrated from the 24-240mm f/4-6.7 zoom to the 24-105mm f/4L zoom. Buying refurbished lenses from Canon, and then only when they are on sale, is a way of not losing out when you do things like this. If the sale is good enough, you can later trade the lens at MPB for about what you paid for it. Trade in value depends entirely on the condition of the lens regardless of whether you bought it new, refurbished or used. It's sort of like an inexpensive extended rental. I bought my prior copy for $80 and traded it for $80. This one was $100.

Canon makes only two 50mm prime lenses in their RF mount. This $200 f/1.8 STM lens and the $2,300 f/1.2 USM lens. I had a copy of the EF version of the f/1.2 last summer, which requires an adapter and foregoes some of the benefits of the RF mount, and would love the RF version but it's big, heavy and very expensive so that's unlikely. There are rumors of an RF 50mm f/1.4 lens but until then, the f/1.8 STM lens will have to do. Here is a comparison of the two RF lenses from The Digital Picture.

The f/1.8 lens is not really sharp at wider apertures, especially at the edges, and the quality of the bokeh is harsher than the faster, more expensive lens. But for a small fraction of the price it's not bad. I tested this copy out yesterday, some shots are wide open at f/1.8 just to test.
