  1. Unlike Sony, Canon, Nikon or any of the other mainstream brands that went 100% electronic connections to control everything, Pentax retained the mechanical control over the aperture settings to this day. It never occurred to me to look for a DA to NEX adapter until I saw a picture of a DA to Fujifilm X-mount adapter at another forum. The Haoge adapter I bought from Amazon has a zebra ring around the adapter body which should move the lever inside the adapter side to side. Which in turn would push the aperture control linkage on the lens to open and close the diaphragm. I am wondering whether a DA lens aperture would click into place at every 1/3 or 1/2 stop or will it be like a cine lens without clicks - probably the latter.
  2. One of the best mirror lens would be a Tamron Adaptall-2 SP 55B or 55BB. http://www.adaptall-2.com/lenses/55B.html The comparison tables in the link above suggest the Minolta 500 mm f8.0 would be a good choice as well and you won't have to fiddle around with an adapter either! As for the image quality between a mirror lens and 2x TC plus 200-300mm lens, too many variables to say yay or nay. Generally, a first rate 1.4x TC plus a fast 300mm MF lens would give you superior image quality than a mirror lens but the cost for them would be a few times higher too.
  3. Whoa, now that makes me feel real old - talk about technological generation gap!😀 In the Menu: 4th page under the 2nd Tab, enable "Release w/o Lens". This will let you trip the shutter without any lens in front of your camera. When I mount any of my legacy lenses to the A7II (along with an appropriate contact-less adapter), the camera acts as if there is no lens mounted. Even so, I can still manually focus and adjust the aperture range with the focus and aperture rings on the lens. Every DSLR and MILC bodies will automatically adjust the exposure settings when the diaphragm opens or closes (Aperture Priority mode). Whether this is done manually by turning the aperture ring on the lens (myself) or by turning the front dial (default setting) on the camera to electronically set the aperture opening via the contacts on your native lenses (you), the camera does it's best to set the appropriate exposure setting. For sure, it's a lot more convenient to shoot with native lenses but other than the lack of Auto-Focus, shooting with legacy lenses without contacts has a certain charm and rewards. In fact, I probably will not invest in any Sony FE lenses other than the 28-70 kit lens that came with the camera.
  4. Of course, shooting with legacy adapted lenses means aperture priority or manual. That's just par for the course when one shoots with Pentax cameras and lenses from as far back as sixty plus years. What these DA to NEX adapter (hopefully) allows me to do is to manually open and close the diaphragm on the current Pentax DA lenses without aperture rings. If the adapter I just purchased can do that without being to fiddly, I would be happy enough.
  5. Follow-up: There seems to be quite a few brands of these type of adapter after all. I searched for DA to NEX adapter and quite a few of them popped up in eBay. The same search in Amazon.ca led to this: https://www.amazon.ca/gp/product/B078HJ5JS9/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Although the better priced adapters are available on eBay I chose Amazon for their much quicker turn around time. I just hope the adapter works as it should.
  6. Does such a beast exist? I mostly have legacy PK mount lenses for which there are lots of adapters available (and have) but I do have a few modern PK AF lenses without aperture rings that I would like to try with the A7II. Any links or pictures of the adapter would be much appreciated. Thanks,
