end of the month review: Cosina Cosinon 55mm f1.4

what a month (for me); my first SIC with an M42 lens, first SIC with the K-5 IIs body....

obviously, I bought a used copy of the Cosina (from eBay - $65) with the expectation that this Tomioka-design should provide excellent shots.....

the Cosina 55/1.4 is a joy of a lens to use - sharp and crisp when you want it, beautiful dreamy bokeh when you want it...

super color rendition (mine tends to oversaturate blues, but once I learned that, I could compensate in post), superior build quality (built as well as any of my Takumars); the only downside to using this lens all month was it's lack of modern coatings on the glass - I tried a couple of sunset shots with it and the direct blast of light into the lens creates an amazing reflection and you can see the aperture-shape in the image...

additionally, my copy's aperture ring, while still 'clicky', tends to turn easily if I don't pay attention to my finger on the lens - if I drag my fingers during focusing, I'll catch the aperture and turn it also...

but there is so much Art in the captures, I didn't mind these two issues....

some shots with the Cosina:

overall - highly recommended if you are looking to add to your M42 collection
