LocalHero1953 Posted August 26, 2017 Share #1 Posted August 26, 2017 Advertisement (gone after registration) With my simple brain, I have interpreted 1:1 macro as meaning that a 1cm subject should occupy 1cm on the sensor. The Leica web page for this lens states "delivers impressive macro exposures with a reproduction ratio of 1:1". I have just checked it against a ruler, and it is nowhere near 1:1. The maximum width it can focus on is about 53mm and the maximum height is about 32mm. For an APSC sensor this implies a reproduction ration of just over 1:2. I see (from wikipedia) that it is customary to take liberties with this ratio for crop sensor cameras, so if this had been a full frame sensor, the reproduction ratio would have been about 1:1.4. Still not 1:1. You are warned. Quote Link to post Share on other sites More sharing options...

floyd Posted August 26, 2017 Share #2 Posted August 26, 2017 Hi Paul did you change the focus mode to AF with the macro symbol. on the T checking against a ruler I get just over 23mm 1 Quote Link to post Share on other sites More sharing options...
floyd Posted August 26, 2017 Share #3 Posted August 26, 2017 This was on a tripod with auto focus as close as I could get. Welcome, dear visitor!

LocalHero1953 Posted August 26, 2017 Author Share #4 Posted August 26, 2017 D'oh! No I didn't. I was using manual focusing. Yes, I can get the same in AF for macro. Thank you. I knew I'd get into trouble by posting without investigating closely first! Is there a way to get this close with MF? Quote Link to post Share on other sites More sharing options...
floyd Posted August 26, 2017 Share #5 Posted August 26, 2017 Yes change the info setting to the second choice as you turn the focus ring a distance scale will appear, its very surprising how far you have to turn the focus ring to get that very close focus. The focus ring moves a lot for very little change of focus, but it is very accurate. 2 Quote Link to post Share on other sites More sharing options...

Ah yes - I'd seen that scale, but didn't realise that you could focus right to the end - it seemed to stop, no matter how much I turned. Yes, you have to turn a long way!
