    It's a mystery for sure. Are there lens sections that just surround the build and have no effect on the elements inside? If so, moving the section front to back about a 32th of an inch would effect focus? Logically one would assume so. Having never taken a lens apart totally, I wouldn't know.

    Is it possible the ring is torqued in some way and does not actually compress flat in place? I noticed it isn't sitting flat in your shot. I have had something like that happen in other items when I thought the mating was clean. Perhaps some debris or burr on either side of the ring? Here's another radical thought. Is it possible the ring is actually a temp spacer while the lens is being constructed? To be removed while the last few parts are being placed and inspected? Is it possible to get a exploded view of this lens to see if that ring is supposed to be there? Back in the day I've worked a few assembly lines where I had to remove parts that were there to hold alignment or whatever until my stations parts go on. Just a thought.

    Your inquiry was a bit open. Are you intending home family event/party type of video capture. I almost typed video taping, but that is so analogic. Are you seeking video surveillance? Family recording is well within economical means right up to 4K. So is surveillance. Getting quality is easy these days. I agree, Alan stated B&H website and it is indeed a good starting source of search. Family recording cameras are still sometimes referred to the throw back title of handicam. Even baby monitors are 4K. The one caveat here is with any surveillance, or baby cams is if they are wireless, it is imperative to create your own new tough passwords as most wireless uses the 'convenience' of the internet to send you your images of baby to your phone while on the golf course which opens your personal feed to possible intercepts of your signals. There is no question this happens every day with wireless cameras on the internet. And always get 1080 HD as the base minimum. That said, from B&H: Video Cameras | Digital Video Camera | B&H Photo Video WiFi & Wireless Cameras | B&H Photo Video

    I agree with the statement of too real. Are you not aware of the 'soap opera' look of video. Where everything looks too sharp and detailed and appear to be in the same room with you on a bigger monitor? The same goes for UHD quality stills. In video, we actually use settings of DF or NDF to 'smooth' out the edges. Or change recording speeds. Alan perceives and doesn't like the edges and rather prefers the film look. Today's digital cameras have detail settings one can use to blend the edges more, thus giving the impression of film. It depends on the photographer whether she is going for the realism pop out effect, or the filmy softer look. It's not a myth. Digital is computer software and sensors recording more than the eye can process and we tend to see it as too crisp more or less for the lack of a better description. I think this website in general would be more frictionless and amicable if people would respond to the post content instead of confronting the author on why they posted or adding extra personal comments. That is never conductive in forums. We have enough antagonistic terrorism going on in the streets right now to be sitting here defending everything one posts. Stay safe.

    Since you converted that image, which is outstanding by the way, is it possible that some filter is set that you're not catching. It also looks like you lightened his face as I would have expected with the strong light that the face would be in more shade and perhaps that touch up if done could shift densities/hues as well that you're perceiving.

    Well, doesn't setting ISO make the camera adjust the shutter and aptr to that speed? I change the ISO and watch the camera tell me it's over or under exposed. How is that not part of the equation. People see the change and that's all they need to know. Many aren't processing the "three steps of exposure" like some science paper. Before I take a shot, when I set the ISO, I receive information from the camera. The image appears over or under exposed to the viewer regardless. I believe people are also accepting poorer exposed images with less dynamic range as today's norm, even though the detail can be higher.

    I let mine grow wild, got it designated as a wetland and call the walkway a nature path.

    Cheapest and most healthy are eight bladed manual push mowers. But based on that logic, we need to go back to brownies and stop buying batteries.

    Not well known fact. With the advent of mulching mowers and no bagging cuttings, the backyard composters manufacturers saw a drop of 60% of their gardening accessory market share and litigation is still ongoing against Toro.

    Naa. Lawnmowers will just have wifi and a screen on the handle. You'll have embedded phones in your head. I have a few instamatics buried somewhere, plus I've a very small small collection of bellows cameras and echta cams as well. I love them. And they look great in my bar area. 10 or 15 of something is a collection, 3000 of something may be called a obsession. I'm still dealing with the fact that a camera I used in the 70's is considered a antique. What's that make me?

    I think there's a few cameras with the viewfinder offset from the center, so I wonder how many people poke themselves in the eye or try to look through the shutter button til they get used to it. The Sigma lens focuses opposite than I'm used to and getting used to it slowly. Or maybe I'm just getting dyslectic in my old age.
  15. sigmaalex920
    Well, I'm not that good looking so that blows that theory.
