While I find that it is easy to focus and be correct most of the time when the camera is in the zero position, as soon as you apply movements, a loupe is critical. I use Maxwell screens, so the image is very bright, but I find it beneficial to use a loupe with the lens stopped down to see the focus across the ground glass.Thu, 07 Aug 2008 11:47:55 GMTsdphotohttp://www.traditionalphotographer.net/forums/Topic925-27-1.aspxI always use a loupe to check focus with my 4" X 5" cameras. I may run through the focus to check and also may try to confirm focus all the way through the image at the working aperture if there is enough light. If not, I will just check my tables and measure to confirm the DOF and the Depth of Focus.<br><br>RichThu, 03 Apr 2008 15:40:06 GMTnaturephoto1http://www.traditionalphotographer.net/forums/Topic925-27-1.aspxMy eyesight is such that I have to use a loupe.Thu, 03 Apr 2008 08:19:12 GMTeric rosehttp://www.traditionalphotographer.net/forums/Topic925-27-1.aspxI use one and it isn't a problem. Just a part of my 4x5 photography.<br>However, with my 4x5 pinhole camera it isn't applicable :)Wed, 02 Apr 2008 19:21:25 GMTPhotoBobhttp://www.traditionalphotographer.net/forums/Topic925-27-1.aspxI use one all the time for critical focusing, then again, I'm only shooting 4x5. I can almost focus it without one, although back in the days when I wore contact lenses, it was essential (and the main reason I quit wearing them). I bet that if I was shooting one of the bigger formats, I could get by without one. I do think that most modern lenses are sharp enough not to need one.Wed, 02 Apr 2008 12:49:13 GMTroteaguehttp://www.traditionalphotographer.net/forums/Topic925-27-1.aspxI keep reading on all the forums how people use a loupe to focus. I realize I do contact printing but even when I was using 4x5, as soon as I put a fresnel on the GG I noticed that when I focused and the checked with a loupe, I did not need to adjust the focusing. I have not used a loupe in years, with 8x10 and 12x20 if it looks sharp on the GG then it will look sharp on the print.<br><br>Can it be that advances on lens manufacturing have made the loupe obsolete?Wed, 02 Apr 2008 12:20:43 GMTJorge Gasteazoro
