jaapv Posted January 8, 2018 Share #1 Posted January 8, 2018 Advertisement (gone after registration) So how much difference in angle of view does a zoom make? Here is the 55-135 at both ends of the zoom rate: 55 mm Welcome, dear visitor!

scott kirkpatrick Posted January 8, 2018 Share #4 Posted January 8, 2018 OK, I'll play. First the 11-23 at its 23mm setting.

jmahto Posted January 9, 2018 Share #7 Posted January 9, 2018 Advertisement (gone after registration) Since I never used zoom for a long time, it is not in my muscle memory. My issue with zoom is that I often forget that I can change FL. Paying attention to one more thing is asking for too much. 1 Quote Link to post Share on other sites More sharing options...

jmahto Posted January 9, 2018 Share #9 Posted January 9, 2018 That's what this thread is for... Actually I liked the zoom implementation for my old D-LUX5 (maybe same in new ones too). The zoom could be configured to move in steps (28,35,50...) and *most important*, it remembered the zoom value between camera switch off/on on sleep off/on. Therefore if you wake up the camera from sleep then in goes back to the old zoom value. Of course, it is same behavior as in changing zoom by turning a mechanical ring (which is decoupled from electronic control). But if I have to design a proper zoom lens, then I will ask for electronic control (as in many P&S). That will allow my D-LUX kind of behavior. You can also have *auto-zoom* where camera recognizes face/body features and zooms into head and shoulder portrait, with focus on eye! Is there a job opening in Leica's product development?

FlashGordonPhotography Posted January 9, 2018 Share #10 Posted January 9, 2018 Double the focal length and you double the size of the subject in the frame. Simple math. So, I've never had any trouble visualising focal length changes. Fun to see visually but if you know the math then it's actually easy to see it in your head.

scott kirkpatrick Posted January 9, 2018 Share #11 Posted January 9, 2018 Since I never used zoom for a long time, it is not in my muscle memory. My issue with zoom is that I often forget that I can change FL. Paying attention to one more thing is asking for too much. My practice is to set the zoom at one of the focal lengths that I am familiar with (e.g. the equivalents of 21, 28, or 35 full frame) and then move to make the picture work. But with telephoto focal lengths, you often can't move enough to make a difference, so it is necessary to frame with the choice of focal length. 2 Quote Link to post Share on other sites More sharing options...

Gordon The other approximate math I use is 1/4 MP in crop when you try to do *digital zoom* to 2X. Example: 180mm equiv crop from 90mm lens is 6mp on CL (24mp). Therefore if 6mp doesn't bother you (still prints great A4) then who cares about the zoom? Edited January 9, 2018 by jmahto Quote Link to post Share on other sites More sharing options...
scott kirkpatrick Posted January 20, 2018 Share #13 Posted January 20, 2018 For when you can't zoom with your feet: 55-135@135: C1000868 by scott kirkpatrick, on Flickr and at 55: C1000867 by scott kirkpatrick, on Flickr and with the CL 23/2.0: C1000847 by scott kirkpatrick, on Flickr Some year there will be tracks electric wires, and a train to the airport, but not soon... scott Quote Link to post Share on other sites More sharing options...
