I received my Jupiter-9 lens in the mail about 1.5 weeks ago, and I finally had a chance to use it yesterday. The Jupiter-9 is a lens made in Russia, available in various mounts (mine is M42, easy to use on most DSLRs), its 85mm focal length, and wide aperture of f2.0 make it a fine lens for portrait photography.
It seems to be selling for around $120USD or so (plus shipping) on Ebay these days. I paid about $140AU total for mine, as I wanted a good condition example, and this particular example included the plastic hard case, both caps, and a lens in reportedly excellent condition. I was not disappointed when it arrived, the condition was like new. For anyone interested the seller was petersburg_deals. Shipment was quite quick considering it was from Russia.
Down to the lens itself. I find it to be very sharp, but I have only tested at f2.8 and f4.0 so far. Most reviews say the lens is a little soft at f2.0, but the kind of softness that works great in portrait photography. I find the colours to be great, let me know what you think. Here are the first lot of test shots. You can check out all the other photos I’ve taken with this lens in my Jupiter-9 Flickr Set
