sean_reid Posted November 22, 2009 Share #281  Posted November 22, 2009 Advertisement (gone after registration) Dear Sean, How much faster is the AF in the GF1 than in the LEICA X1 in absolute figures (secs) ? Will the GF1 be more close to DSLR AF or still nearer to standard P&S speed but just a tad faster ?  Thanks again in advance Hexar  I do not have the necessary equipment to measure that in absolute specs. One would need proper equipment and would need to test under a variety of different conditions. Photographing a stopwatch on screen only covers one kind of lighting condition.  I still need to do the file quality/ISO comparison tests for the X1, DP2 and GF1 but then I need to concentrate on the S2. I also have major surgery coming up (would prefer not to go into details about that) and so will need to take some time away from camera testing in December.  Cheers,  Sean Link to post Share on other sites More sharing options...

hexar Posted November 22, 2009 Share #282 Â Posted November 22, 2009 Thanks Sean. What is your preffered ratio 3/4 or 2/3 ? Â The view of field between the 20mm on the GF1 in 3/4 ratio does differ from the 35mm in 2/3 that much as it would be in both 2/3rds would it ? both focal lengths in 2/3 make a bigger difference and that`s why we should not compare the LEICA X1 35mm with the 20mm Pana in the way we would with similar camera`s as far a field of view is concerned. Anything to this from your point of view ? Â Best regards Hexar Link to post Share on other sites More sharing options...

hexar Posted November 23, 2009 Share #286 Â Posted November 23, 2009 Hallo Sean, Â Is there a way to lock AF and not exposure at the same time ? I am still strugling with the fixed AF without having to get a fixed exposure. So I point my camera (X1) to a subject at let`s say 4 metres and then want to take an other subject with keeping the AF locked on this 4 metres but with automatically get new exposure. (sort of AF LOCK feature) Â Thanks Hexar Link to post Share on other sites More sharing options...

Now you can move the camera and recompose with a new exposure and preserve the focusing distance . The question is how fluid is it to shift to MF from AF and then back for the next picture? Not the best solution I admit.  For zone focusing this could be very useful; simply AF to a spot and shift to MF for subsequent series of pictures; no need to fuss with the on screen distance scale.  Take care!  Furrukh Link to post Share on other sites More sharing options...
hexar Posted November 23, 2009 Share #288 Â Posted November 23, 2009 Hallo Sean, Â In the dpreview I found the following AF setting: The 'H' modes are 'High Speed', which focus faster but at the expense of a momentary freeze of the live view display. Â What about this. Did you try this setting and what is of any help in speed ? Â Regards Bert Link to post Share on other sites More sharing options...
hexar Posted November 23, 2009 Share #289 Â Posted November 23, 2009 Thanks Khanosu. So focus / half press shutter button/ Switch to MF and up you go right ? Link to post Share on other sites More sharing options...
hexar Posted November 23, 2009 Share #290 Â Posted November 23, 2009 An example to use this technique would be to shift to F8 ( in good lightning conditions) AF at a point at 4 metres for example and you can shoot very fast ahead between 2 metres (1.9 metres exact) and infinity without having to worry about AF speed , shutter lag . A good way to work with a camera like the LEICA X1 but again you have to know what you are doing. (or/and experiment a lot) Link to post Share on other sites More sharing options...
hexar Posted November 23, 2009 Share #291 Â Posted November 23, 2009 I just had an other look at the dials on top of the X1 and see that in order to shift to Manual mode you have to turn a tiny ring around the shutter button, WIll this be possible at all when yoiu have the shutter button pressed half way to lock AF ? I looks a bit awckward but maybe someone can tell me the practice here. Link to post Share on other sites More sharing options...

Â I believe you toggle between AF and MF like this: Â Press the AF/MF button embedded within the wheel (right lower part of the back); turn the wheel to select AF or MF from a short menu. I believe the menu has only two selections; saw it somewhere in some review. So perhaps turning the wheel one way takes you to MF and the other way to AF; if that is the case then the process can be somewhat fluid. Â Take care!

hexar Posted November 23, 2009 Share #293 Â Posted November 23, 2009 Thanks, Maybe Sean can help us out here how it is done most fluidly. MF modes are obviously very important in this camera so this point should be quit clear to me. Regards Hexar Link to post Share on other sites More sharing options...

MF modes are obviously very important in this camera so this point should be quit clear to me. Regards Hexar  According to online reviews the AF/MF menu has three selections; AF, AF Macro and MF. If the menu is not cyclical then switching between AF and MF could be done without looking at the menu provided AF and MF selections are at the opposite end with AF Macro in the middle; if it is cyclical then one will have to rotate the wheel carefully. I am sure Sean will make this clear after he has recovered from all the dessert intake at the wedding.  Take care!  Furrukh Link to post Share on other sites More sharing options...

Â You've read the review already, right? If yes, you might want to reread it to clear up some of these details. That switch has nothing to do with manual focus mode - fortunately.

No need for the wheel unless desired.  Cheers,  Sean Link to post Share on other sites More sharing options...

So the cycle goes like:  AF, MF, AF macro, AF, MF, AF macro  So if you are in AF then one press takes you to MF and if you are in MF then two presses take you to AF. Going from AF to MF locks the focus distance. One can do this without looking at the screen or rotating the wheel which is very nice!  Take care!  Furrukh Link to post Share on other sites More sharing options...
