Summarit 1.5
Came with the IIIc, some haze and a lot of fine scratches on the front element. The result is a slightly dreamy, glowing, lower-than-normal-for-summarit look. I like it but only for very specific shots. I'm on the fence about if this is enough of a reason to keep it.
Industar 61 L/D
First LTM lens I picked up, well in advance of a camera. I wanted it for its sharp, high contrast reputation. I've been trending towards lower contrast looks since then, but still appreciate it for specific work.
Jupiter 8
Just picked this up yesterday as a middle ground between the Summarit and the 61. A friend has one on a FED2 that produces excellent results. I haven't had a chance to shoot it yet.
On the SLR side, I have a 50mm 1.8D. Simple, gets the job done. I picked up a 1.4 advertised as a AI lens but it was a late non AI lens... I'm still deciding what to do with it.
