  • From pressing the shutter release to getting the image is what most folks I know call shutter lag. The point is that mirror flap has nothing to do with viewfinder lag and you seem to be conflating ...
  • Right. Show no proof, just claim that you know it. I've been doing photography for 63 years. I did my own darkroom work for decades and had nice film gear that I still own out of sentimentality. I ...
  • Shutter lag is different entirely from viewfinder lag. Since you don't understand that you're point is worthless and your "contributions"  are also. Ignorance abounds here and yours is ...
  • Slooooowly moving and stationary. No challenge at all I'm sure for the lag of a mirrorless EVF but that does nothing for your point. Hey, if your mirrorless allows you to follow all of your pokey, ...
  • I understand your zealotry and I also understand that you actually have no concept of the conditions under which those photos are taken. Baloney. Until I see someone shoot a falcon flying at high ...
  • The EVF vs OVF debate is somewhat like the smartphones-will-take-the-DSLR-market "real soon now<TM>." The protagonists of the "new paradigm" do not accept the same set of facts as the "nah, it's ...
  • The lack of AF tuning built into the body will make things a bit harder. The starting point should be making a focus target, measuring the distances required, and then comparing the AF point using ...
  • Replied in Sigh...
    Oh sure. Until then I'll take my high speed bird-in-flight peregrine falcon photos with a DSLR and a 150-600mm lens. You don't seem to get it: it's not about hate of smartphones. I bet nearly ...
  • Funny, you're arguing against words I didn't write. That's called a "strawman argument." What I said is this: One thing that would go a long way to reduce the scoffing at the phone boosters would ...
  • I think it isn't the smartphone that gets sighs bordering contempt, it is the people grossly overstating the universal superiority of smartphones that lies just around the corner, making them ...
  • You must have misunderstood the whole point of the process I used: unlike the description Sigma gives of their process, my process requires very little lens to dock swapping. Check the ...
  • As I said farther down the thread (https://www.dpreview.com/forums/post/57304660): Now, at this point, after making a good printed target, after finding a good alternative target 417 yards away for ...
  • People I don't know and have met for a moment ask me that same thing several times a week--week in and week out. I hang out a lot at a site where peregrine falcons make a living and raise their ...
  • Saying "Smartphone owners [are] buying more cameras" is like saying, "U.S. adults are buying more cameras." 220 plus million U.S. adults are smartphone users. Some of them buy ILC cameras? I'm ...
  • So are you saying that magazines with substantial photographic content are a tiny part of the print market? Calendars and books with photographs are a tiny subset of the print market? I must have ...
  • I get what you're saying. You seem to only understand process offset technology and ignore modern digital printing used for high speed print on demand (POD) products. My familiarity with ...
  • You are using a strawman argument because no one is insisting that any printer prints by an additive RGB process. You are stuck in an offset mindset and failing to get the point here, Bent. Loosen ...
  • The point is that using 4-color-only CMYK is not done when color photographs are being reproduced by people who want the photos to be well-represented. No one is claiming an RGB print process. The ...
  • And I did CMYK proofing and it was quite like what I got. It wasn't what I might have gotten from a printer who was using an extended gamut favoring RGB. You are apparently totally unaware of ...
  • Your absolute statement is an over simplification because not all color printing is done by standard offset process CMYK-only printers. Not all color printers have only the 4 colors CMYK. Go to a ...
