Nikon 50/3,5 auto micro pre AI

This lens is cheap among macro lenses, but the quality of it isn't cheap.

Miranda MC 24/2,8 PK A mount

in Lenses world, Miranda is known as brand with their own mount. However this lens is said not produced by the real Miranda. Some say this is Cosina made lens. it's character, build. indicate that.

My first impression; 

It can focus close for macro.  around 10cm, but It's not real macro lens.
At infinity, F8 is best performance.
very low distortion

wide open

Against strong light

 

Close focus, wide open

Canon FD 35/2 SSC on NEX5

I own this lens for some time. I rare using it since many lenses come and go.
Now this is my 35mm left. I took it out in sun beam. with only 0,3m MFD enlargement cannot be ideal for macro works, but that's OK, this is not macro lens. Thanks to NEX firmware which allow me to use peak focusing. great help for such condition.
Here it is...all cropped.

Voigtlander Heliar 15/4,5 Aspherical superwide, LTM

I heard only good things about this lens. Small, sharp...even you can use it wide open at infinity, and sharp still
Something that leave Leica behind in wide angle class. and that's just right.
Architecture, landscape? let this tiny lens help you. you won't be dissapointed.
Dont expect nice bokeh

Malioboro street

There's color shift on corners in my Sony NEX5, this is not happen in my friend's NEX5N

Ros-In Hotel, Ring Road selatan Jogja

Fujian 35/1,7 C-mount

Some people say this lens is just a toy lens. for the price, yes.

However center sharpness is easy with it. but Don't expect sharp on edges!

Let just see result. center is sharp, and you can see letters EMERGENCY is getting softer from Y to E letter. It's like using tilt lens :D, if you want this effect, go get it. but if landscape with infinity is what you want, forget this lens.

With right technique this lens can produce nice image, see below.
I was surprised myself with this result. very nice sharp and detail. well, in center :P

SMC Pentax 50/1,2

The lens isn't in mint condition. Some pain loss, it looks like re-painted on front part.
