comment:This is the second cheapest Sony lens behind the 50 f/1.8. With the caps on it looks practically identical to the 50/1.8. Both use the less common 49 mm filter size and lack hoods. The main body is also shared with the other two Easy Choice Lenses (35/1.8 and 85/2.8). The 30/2.8 has a 180 degree focus throw like 85/2.8, but the barrel doesn't extend as far as that lens.

Unlike the other macro lenses and the primes the tiny front element of this lens is close to the front of the lens and rather unprotected. There is no provision for a hood other than the filter threads.

This lens has much better image quality than the discontinued 28 f/2.8 full frame prime. The semi macro mode of the Minolta AF 28-135 has a similar field-of-view except with considerable purple fringing.

As long you can get very close to the subject this lens works very well. The 30 mm focal length gives it generous depth-of-field. It has slightly better contrast than the Tamron 60/2 at 1:1. It is amazingly sharp when used with a generic 7-element 2X teleconverter. The combination doesn't quite have the flatness and consistency of the 60 mm Macro, but the center sharpness is great. SAM AF works well using the Kenko Teleplus 1.5x DG and 1.4x DGX teleconverters.

The more I use this little lens, the more impressed I am with it. The 35 f/1.8 is probably a better everyday lens because of its AF accuracy.
