Zhongyi Lens Turbo and M42 lenses

2013-10-21 Posted by Hin Man
My genuine adapter is loose when mounted on Lens Turbo. But once the M42 lens such as a SuperTakumar 55mm f/1.8 or other similar m42 lens is mounted on the Lens Turbo K adapter, my setup works really well without any play. However, the same setup doesn't work with one of my lens with the Industar 50-2 50mm f/3.5 as the lens is too small to get tighten up with the M42 to K adapter. Please do check on various M42 lens and you may find out what works and what does not.

If any of you are interested in using M42 lens on NEX directly. I have a blog post that may be of some interest to you especially if you have a Konica AR mount

http://www.techtheman.com/2013/08/how-to-adapt-m42-lenses-on-nex.html

The premise is the smaller size on the Konica AR to NEX adapter and together with the silver screw mount adapter for M42 to Konica AR, one can use the M42 mount lens with a smaller setup. Not that it shorten the overall length but it will look smaller due to the smaller AR adapter



more detail in blog post

When using Lens Turbo, here is my setup with genuine M42 adapter mounted inside the Lens Turbo adapter.



Super-Takumar 35mm f/3.5 mounted solidly with
genuine m42 to K adapter + Zhongyi Lens Turbo for k-mount

The above are not good pictures to show as the lens has better image quality when used without the LT but I like the 37mm FOV with the adapter.

I always prefer the genuine m42 adapter, if you have loose stopping plate or the screw on the 3rd party adapter, you can easily get your camera/lens stuck. I wrote about my bad experience with Bower adapter in m42 nightmare article with 3rd party adapters in which I was scrambling to free a stuck adapter from an adapter with loose stopping plate and screw.

Konica Hexanon AR 40mm f/1.8 Pancake on Sony NEX 5N

Konica Hexanon AR 40mm f/1.8 Pancake on Sony NEX 5N
I just got my Konica Hexanon AR 40mm f/1.8 pancake. Its size is almost like the Sony E 16mm f/2.8 pancake. However, it is a bit of disappointment as the Konica AR to NEX adapter makes the pancake appeal quickly disappear as soon as I mount the lens on the adapter.

Lens is extended to longest end as it reaches 0.45 meter
minimum focusing point
it should be smaller at infinity focus point

However, the lens is still a reasonable sized and performance is good for its lower cost of ownership. The Olympus Pan F 38mm f/1.8 will be a much smaller setup due to smaller adapter. Image quality may be better in the Olympus Pan F lenses but the cost is probably 3-5 times of the Konica pancake.

I did some casual snapshots in the weekend with Sony NEX 5N. Handling is quite good in the focusing ring. And I have a lens hood fit for the 55mm odd filter size. Wide open shots has a glow but when stopped down to f/2.8 and smaller, the glow don't seem to bother as much. I shot most of the snapshots in f/5.6.

Impressions & Notes
  • Lens is small and lightweight. It is similar in size to the Sony 16mm f/2.8 pancake.
  • Size of the Konica AR to NEX adapter is smaller than other SLR type of adapters but it is still quite big and once the lens is mounted on the adapter, all the pancake appeal will diminish a bit if size is what you are after
  • In real use in the field, the lens has good performance for its low cost. The one thing I notice is a glow on details when the lens is shot wide open. When I stopped down the lens a bit to f/2.8 and smaller, the glowing edges of fine prints in test pictures seem less obvious
  • The lens aperture stops are in full stops but I can still engage the aperture in between stops.
  • I especially like the focusing ring for ease of focusing
  • A good lens hood is recommended for this lens to have better control over flare
