  1. Do yourself a favour, spend three bucks to pick up a 40.5mm wide angle lens hood made of metal and put it on your lens. Chances are there won't be any vignetting at all since the lens hood is designed for full format coverage. I have bought at least half dozen conical lens hood for Pentax lenses and I have never had any of them cause vignetting on my Pentax Aps-c cameras. Going from needing a lens hood for your 16-50 to seriously contemplating a purchase of fast prime lens is one hell of a jump but that is irrelevant. At the end of the day, you are still without a lens hood for the 16-
  2. All of this discussion is just a mental exercise, it better to leave the lens hood as a conical lens hood - don't ever need to worry about it's alignment.
  3. @Chrissie, It would be impossible to carve out a tulip shaped lens hood from a conical lens hood at home whether the conical lens hood is made from metal or plastic. I can't begin to imagine what kinds of tools would be needed to do so, it would been best if Sony had made a proper lens hood for the 16-50, which Sony unfortunately did not. @Dennisspeaks, It will cost you a cup of coffee or two to pick up a 40.5mm wide angle, metal lens hood from eBay. The issue of vignetting, it may turn out to be a non-issue since these lens hoods are based on full format coverage, not aps-c.
  4. From eBay buy a metal wide angle lens hood (sized to your lens' filter diameter). When it arrives mount the lens hood to the lens and take pictures of a blank white wall at the focal length of 16mm. What you are trying to determine is how much vignetting the lens hood causes. If there is no vignetting or if you can live with the level of vignetting the lens hood causes, you don't need to do anything. On the other hand, if the level of vignetting is unacceptable you will have to remove the excess material from the lens hood. Place a sheet of wet/dry sandpaper on a flat surface and gen
  5. 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
  6. 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.
  7. 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
  8. 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.
  9. 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.
  10. 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,
