Film To Digital Konica S3 Rangefinder with Sony NEX-5 Sensor

Frankencamera by Oliver Baker
Give Oliver Baker an NEX-5, a Konica S3 fixed lens rangefinder, and a 3D Printer and what do you get? The Frankencamera.

Oliver combined the mechanical features of the Konica S3 RF and the digital components of the NEX-5 to create a new camera. The back of the S3 was replaced with a 3D printed replica, via selective laser sintering. The new back holds the NEX-5 sensor and related electronics.

Konica Hexanon 57mm 1.2 on NEX-7

We've seen what the Sony A7r can do with the Konica 57mm f/1.2, now it's the NEX-7's turn. We actually took these shots almost two years ago. The 57mm on the NEX-7's APS-C sensor produces an equivalent field of view of 86mm. The lens having such a large aperture at f/1.2 is perfect for isolating your subjects.


The shots are most likely at f/2.0 instead of wide open. We had to stop down since it was producing better results that day. We love greens that are produced by the Sony sensor and the shots below show it well.

Can you tell a big difference between the 2 year old NEX-7 shots vs the recent A7r shots? Our biggest lesson is to process your files as soon as you can.

Sony A7r with Konica Hexanon 57mm f/1.2 shot by NEX-7 with a Leica 60mm Macro-Elmarit-R
Here are some of our test shots from the Sony A7r and the Konica Hexanon 57mm f/1.2 lens. The lens was mounted on the A7r using a Konica AR lens adapter. We wanted to test out the lens at f/1.2 the whole time and it was fitted with a 4X ND filter to battle the sun. The 1/8000 shutter speed and 50 ISO of the Sony A7r helped at times as well.

The Konica 57mm played very well with the A7r per our standards. All the shots were handheld as we rarely use a tripod. The focusing, at such a shallow depth of field from the large f/1.2 aperture of the lens, was manageable on the A7r. The weight of the lens would make us think twice of walking around with it but the results are hard to argue with. The details shown at f/1.2 is remarkable even at the outer edges of the shots.

The 135mm Lens Battle Combatants Part 1 for Larger Pictures
Here is the second part of our NEX-7 135mm Lens Battle. Part 1 discussed 135mm lens handling on the NEX-7. We tested three prime lenses (Canon 135/3.5 LTM, Konica 135/3.5, Minolta 135/3.5 MD) and two zoom lenses (Canon 70-200/2.8L, Olympus 75-150/4). The zoom lenses were set at 135mm approximately. The lenses tested are around $100 or less with the exception of the Canon zoom.
The shots were taken at wide open aperture (f/2.8, f/3.5, or f/4) and the at f/8. We have labeled each sample a color and a number. The NEX-7 or lens was on a tripod, ISO100, and JPG Fine output. The samples below are arranged as follows:
One is shot wide open. It shows the full scene with standard editing.One Crop is shot wide open with no editing. It is a 100% crop.Two is shot at f/8. It shows the full scene with standard editing.Two Crop is shot at f/8 with no editing. It is a 100% crop.Three is shot at f/8. It shows the full scene with s…

Composite of Four 135mm Lenses at f/8 with the NEX-7
Here is a first part of our 135mm focal length test used on the Sony NEX-7. This gives us an equivalent FOV of 202mm. We don't really shoot much at this focal length but we wanted to see how the NEX-7 and the various 135mm lenses worked with each other. These lenses are around the $100 mark with the exception of the Canon zoom. The lenses tested are:Canon 135mm f/3.5 LTMCanon 70-200mm f/2.8 L EF Konica Hexanon 135mm f/3.5 ARMinolta 135mm f/3.5 MDOlympus 75-150mm f/4 Auto ZoomFirst let's rate the handling. The Minolta and the Konica are the lightest of the group. This makes them the easiest to handle. The Olympus zoom is next and is most versatile being a zoom lens but it is longer than the Konica and Minolta. The Canon LTM is heavier than the first three but is the most compact in size. The aperture ring is at the end of the barrel and when adjusted, it also adjusts the focus. The Canon EOS zoom is the biggest and h…
