Dear Michael, The Mighty Shen Hao came with a 300mm f.5.6 Seagull lens - barrel style with no shutter. The MSH has a packard shutter fitted inside the bellows section. I was initially skeptical about it, thinking that I would need a better-known brand. But my experiments with the new 8 x 10 back and standard double darkslides have shown me that it is quite sharp enough for my purposes. I am disinclined to change it. It is a little awkward to stop down inside the wooden housing of the MSH, but I think a bit of jigsaw and varnish work will cure that. I suspect it is a Chinese copy of a Soviet copy of a Tessar. If I had a field 8 x 10 I might well choose a shuttered version of it as standard lens. I suppose if I could get an unused artillery tractor I could take the Shen out into the open air....
