Zhongyi Lens Turbo and M42 lenses

2013-10-21
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.

Fuji f30 struggles & tips

2006-12-15
After some fuji30 test shots, though I can confirm that f30 is really a great camera for low light photography, I ran into a couple of struggles with surprises and I want to summarize below along with tips that I learned from others

Struggles:

1. Auto mode tends to go into high iso setting such as iso1600 in indoor and pictures are acceptable but I will not rate them as good pictures. I am somewhat disappointed with the auto mode and I try to stay away from Auto mode completely. I try using all manual mode with ISO set for 100-200 outdoor and auto iso400 for indoor. Pictures coming straight out of the camera tend to be soft and flat. And I do get a high number of unsharp images. I try changing 'Photometry' from 'multi' to 'spot' and 'average and I am yet to experiment on the two settings.

2. In bright daylight outdoor, I get many over-exposed pictures in auto-mode with blown sky. I know, I know, many people suggested -1/3 ev for compensation, I have yet to try that

3. AutoFocus AF is relatively slow in keeping up with kids' movement. At first, I thought the f30 is great for taking pictures on kids indoor, I am yet to find the proper setting. Many indoor pictures without flash don't come out satisfactory especially on moving kids' pictures. Perhaps, I need to try more on S priority. As of now, I get many pictures (without flash) that have ghost images due to longer shutter. It is a tricky balance between iso, quality, and shutter speed, etc.

4. The biggest gripe is on the xD card, the proprietary USB connection and the software on FinePix that comes with the purchase. The little plastic cover makes it extremely difficult to connect to the PC. It is very frustrating experience every single time that I connect to the PC. I have never seen anything this bad in transferring photos to PC. The FinePix software that come with Fuji f30 purchase serves no purpose but negative impressions on fuji -- it is not worth installing on one's computer.

5. The xD card with Olympus type H is slower than the my two year old SD card rated at 60x. This is not a surprise as I know this way before purchase. But the first 4 points and the next on Firmware upgrade are all surprises for me.

6. Firmware upgrade. I did manage to get 1.02 firmware on my f30. The experience in downloading firmware to my f30 is really nightmare due to poorly documented instructions in fujifilmusa site.


Tips:

1. Over-exposure in daylight:
I started using -1/3ev and -2 on LCD brightness.

2. Inconsistent metering with 'multi' photometry (subjective)
I am trying both 'spot' and 'average' photometry setting.

3. Kid's moving picture

I am experimenting with 'fast speed focus ON' in menu setting. I am also starting to rely on the flash when necessary on kids picture for indoor.

4. Focus hunting

I am trying to pick focus on constrasty area and practice with different orientation on the camera.

5. Occasional color and contrast seem to be flat (subjective)
I am playing with 'chrome', wb setting, pp

6. Occasional Soft pictures (subjective)
I get suggestion to use a higher aperture f number such as f4 instead of f2.8. I am yet to experiment on Aperture priority

7. Others
Continuous shot to get mutiple
Natural + Light to take double pictures
First and last three shooting
2 and 10 second timer
