Vivitar 24/2 MC

It has 28 first serial number, so it's made by Komine.
I got it in Canon FD mount, so I cannot use it in lens turbo yet.
Looks decent performer.
soft at infinity at wide open, but very usable.
Compared to Vivitar 28/2,5 made by Kiron, it has smaller size and lighter. despite of it has faster aperture.
filter ring is 52mm, while 28/2,5 one is 67mm.

Topcor Auto RE 20/4 Tokyo Kogaku

Images below were taken with this lens and Sony NEX5

You won't get bokeh thing with this lens, it has 0,3m MFD, Flektogon 20/4 has closer. but this lens sharper I think.

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

Sony 16/2,8 SEL

This lens was included when I bought Sony NEX5.
The AF mode is so smooth, sound is very weak, almost silent

Carl Zeiss Jena Flektogon 25/4 exakta

Seri flektogon 25/4 tidak sepopuler seri 20mm, saya kurang tau persis sebabnya. Jumlahnya juga tidak sebanyak yang 20mm. Kalau soal kualitas, lensa ini cukup dapat diandalkan. Sharp, even wide open.

Schneider Kreuznach Curtagon 28/4 Exakta

Brand Schneider Kreuznach  merupakan merk yang cukup ternama di jajaran pembuat lensa berkualitas.

Pabrik asal Jerman ini tidak banyak membuat lensa dengan mount yang ramah untuk DSLR dibandingkan dengan Carl Zeiss. Kalau kita lihat harga, umumnya Lensa Kreuznach lebih mahal dari pada Zeiss untuk spesifikasi yang sama. Hal ini membuat saya penasaran.
Saya sudah membuktikan untuk Xenar 135/3,5 dibandingkan dengan CZ Sonnar 135/3,5. Xenar lebih tajam di wideopen baik untuk close maupun infinity. Keunggulan ini ternyata ada juga pada lensa Curtagon 28/4.
