Taking this lens through it's paces I shot some footage of my son telling me about recycling.
This is a great lens and I don't even need to preface that with "for the cost". I haven't done any side by side with canon's 50mm 1.8 but I've shot plenty with the 50mm 1.4 and this lens is very comparable. I can't quite put my finger on it but this lens produces some very unique shots and in the larger aperture settings the bokeh is nice and soft. It's a full manual lens... It has a focus ring and an aperture ring.
This was shot after about 5 minutes of getting the lens. Shot around f4 outside my house. I think I had the 7D in a standard Portrait profile (didn't feel like doing much post). The first 10 seconds are right off the camera. The next 10 have some small color balancing and the last 10 has a bit more coloring just to see how it holds up.
Unless I'm shooting a portrait type shot I think this will be my go to lens in this focal range. Time will tell as I get some use out of it.
UPDATE: I doubt this will be the go to lens. the 50mm 1.4 is still a bit sharper. But this lens def has a different feel to it and It'll stay in constant rotation.
Total cost: $24.99 from ebay + $11.99 Fotodiox M42 - Canon EOS Adapter from Amazon.
not a bad find for $40 delivered to my doorstep.
