Lens Adapters & Aperture Setting...


Recommended Posts

Advertisement (gone after registration)

I'm trying to understand the unmarked aperture ring on the K&F Concept lens adapter.

I recently purchased the K&F Concept Minolta AF (Sony A) to Fuji X lens adapter to use with my old Minolta AF lenses; specifically the Minolta AF 50mm f1.7-f22.

With the adapter installed (Fujifilm X-E2S), the camera does not show the aperture selected; understandably as this is a "dumb" adapter.

The combination works very well together and I have no complaints.

The adapter has a clicked aperture ring that allows for 9 stops from fully open to fully closed.

Would the 9 stops equate to f1.7, f2, f2.8, f4, f5.6, f8, f11, f16, f22 for the Minolta AF 50mm f1.7-f22 lens?

 

Many Thanks!

    • Fujifilm has a standalone raw converter program that turns your raw images into either jpeg or tiff files. It has quite a few tools, of course you can then import the jpeg or tiff files into image editors for further processing if you want. https://fujifilm-x.com/en-us/support/compatibility/software/raw-file-converter-ex-powered-by-silkypix/ https://fujifilm-x.com/en-us/support/download/software/raw-file-converter-ex-powered-by-silkypix/

    • I am using a Fuji xt30. When I go into the Q menu I can alter the choices, for example to change the ISO, using the touch screen. However, when I try to do this with the rear command dial, it does not toggle between the options. How do I reset or get the rear command dial to do this? thanks  Ravenstonedale
    • Hey Folks- new Fujifilm XE-4 owner looking to upgrade my photo editing skills by using the RAW files to produce a final product rather than the jpegs.  Unfortunately my iMac Photos does not support the RAW files from the E-4.  I just learned that even the most recent version of the iMac iOS system (Big Sur) doesn't support the XE-4 RAW images.  So I'm seeking input on a photo editor that runs on an older iMac (2012 year model w/ 8 mgs of RAM, Intell Core i5 processor and plenty of hard drive storage) that does support Fujifilm XE-4 RAW images.  I am not a professional photographer, just an amateur looking to upgrade his skill and craft.  TIA for suggestions and advice.
