The lens was from Konica rangefinder camera, converted by my friend to Sony e-mount.

All wide open except last one, infinity

Panorama

There's 2 ways to make pano picture. stacking in camera or handphone and do it in software (eg. Photoshop, Microsoft ICE etc.)

Sony NEX has built in panorama mode. This is sample using Konica Hexanon 28/3,5 AE

Taking pano shot with NEX or other built in pano mode camera need steady hands to make horisontal/vertical line. in the mean time, object should be stand still, not moving. otherwise there will be "ghost". see sample below. but sometimes, I shot like this on purpose

CV Heliar 15/4,5

Stacking in Adobe Photoshop, lens was Tamron 28-70/3,5-4,5 adaptall at 28mm

Konica Hexanon 28/3,5 AE & Schneider Kreuznach Curtagon 28/4

First of all, Curtagon was my favourite  amongst 28mm lenses. I just curious of the hexanon which said to be good one. Just got my Hexanon few days ago. Find other post of both lens in here( Hexanon)  and Curtagon, here.

• Based on This Schneider site My Curtagon was made in 1967 while Hexanon AR (which has Focusing ring with checkered rubber inlay, Smallest aperture 16, 7 elements in 7 groups, Green AE mark and Round AE lock button) according to This Konica site was made around 1975.
• Dimension: Curtagon is  smaller but it's little heavier
• Closest focus: Curtagon has 0,25m mark, but it can be turn closer. while Hexanon has 0,3m.
• Sharpness in wide open; I can say curtagon is little bit better, maybe half stop slower make different. Hexanon is sharp too, even at infinity.
• CA control ; Hexanon has lots of CA, worst in wideopen, reduced little stopped down. Curtagon has little in wideopen
• Contrast: Hexanon has better result, later production bring newer coating I guess.
• I wrote before that "I haven't make comparison for infinity distance yet, but I think both has almost similar result". Then I realized something different. It's about edges sharpness. Curtagon win in this case. Hexanon soft at edges. (at least I tried at f8)

Here we go the short comparison I took this morning


pictures below are center crop at wideopen. see CA control,

both here at F5,6, see the color/contrast

Bokeh at 0,3m distance, I think it's at f5.6 Curtagon has 5 angle star bokeh, hexanon 6 angle star (we know what hexa mean ;D)

Flare test

Konica Hexanon AR 28/3,5 AE

According to  This Konica site this lens was made around 1975

• Focusing ring with checkered rubber inlay
• Smallest aperture 16
• 7 elements in 7 groups
• Green AE mark
• Round AE lock button
• 55 filer ring

Some people mentioned this lens if someone asking for good 28mm lens. This is reason why I want to try it. I'm already have Schneider Curtagon 28/4 which I think the best 28mm I ever have.Curtagon is more expensive than this lens.
Other 28mm I 've tried are:
Leitz Elmarit 28/2,8
Enna Munchen 28/3,5
Vivitar/kiron 28/2,5
Tamron adaptall2 28/2,5
Enna Munchen 28/3,5
Pentax SMC 28/3,5

There're only tamron and curtagon left to compare with this hexanon. I guess its better than tamron, looks as good as curtagon, here comparison of Curtagon & this lens

New Ngasem market, background is Pulau Cemeti

between F8 and 11

First impression;
Sharp lens. from closest distance to infinity.contrasty. it has some CA.
