  1. You are mostly correct. For all practical purposes and intents, a 35mm f/0.95 lens on an APS-C camera will give the same depth of field and field of view as a 50mm f/1.4 on a fullframe camera. The ISO-performance of a fullframe camera is also only about 1 stop better than an APS-C camera with the same amount of megapixels. So e.g. a FF-camera with a 50mm lens at f/1.4, 1/100 sec shutter speed and ISO800 produces roughly the same depth of field, field of view and noise performance as an APS-C camera with a 35mm lens at f/0.95, 1/100sec and ISO400. However: the cheap 35mm lens will likely produce absolutely crap quality images at f/0.95. So unless you're into that 'arty dreamy look' of blurry images that are a hazy mess, your money is best invested elsewhere. By the way, the new Laowa 33mm f/0.95 seems to be pretty good stopped down, but that wasn't your intent: https://www.lenstip.com/index.php?test=obiektywu&test_ob=615

  2. Keep in mind that Minolta has been making SLR lenses for almost 60 years -- and auto-focus lenses for almost 40 years. There are lots and lots of great Minolta AF lenses that you can get for next to nothing. They won't have all the bells & whistles of newer lenses -- like anti-shake stuff -- but the optics are probably the same. Plus there are lots of independent lens makers that have been adding to the AF arsenal for just as long. I recently bought a Minolta Maxxum 5 with a Sigma 24-200mm lens for $20. I sold the camera for $30, and kept the lens. That's about as cheap as you can get.

  3. sixzeiss and Jaf, Thanks for your guidance. As mentioned earlier I had opened aperture to "max", but also made other changes as well, so not possible for me to attribute improvements to which change. Using AF-C Wide, while turning off: face recognition, Lock On, and "expand flexible spot" seemed to really improve the speed of focus capture, and these three items plus wide open aperture taken in total have made a big difference to the speed of acquisition, and sharpness of focus. I like the idea of manual focus for stationary birds, but do find the "flexible spot (s)" to allow me to isolate the bird to the extend that auto focus works very well. Manual is certainly a "back up" that will deal with problematic situations, and I have taken your advice to turn peaking down to low, and color red. I've also customized a button to magnify, and find that very useful. Great forum - very helpful. Thanks!
