These are wonderful images: thoughtful, well executed, and evocative. They invite the viewer (at least me!) to go back and look at them again, which is what I’m doing right now.
That said, I’m not sure their success is related to the lens. Aperture values aren’t listed (understandably, there’s no metadata), but the apertures seem small. Not convinced that the pictures wouldn’t have been the same if taken with a Summicron, a Noctilux, or a Summarit. In other words, I find it hard to discern the contribution the Lux makes to the images. There’s no bokeh or vignetting that would illustrate the lens signature and the grain doesn’t allow the sharpness of the Lux to come through. Of course, the pictures don’t need any of these creative crutches and succeed just fine on their own. But there’s nothing that tells me that I need the Lux to take these pictures.
I’d very much welcome Brendan’s view on this topic, namely whether the Lux contributed in any way.
