  • I use a Canon 600D. For locating (i.e. pointing the camera in the correct direction and framing), I use the Optical Viewfinder. I also use the OVF to rough focus the Telescope or Camera lens. I ...
  • In a 'loose' kind of way Yes . The difficulty is getting information on the existing lens. Do note that 10 surfaces limits you to the simpler lens designs, which complete information and many ...
  • Yes, there is free software available (for educational use) called OSLO. It is available from :- http://www.lambdares.com/index.php/oslo-university-program It is however limited to 10 surfaces, but ...

  • >> [snip...] There are perhaps better Micro Four Thirds cameras (e.g. ones with larger viewfinders for easier focusing) for habitual users of legacy lenses.

    Yes Agreed - I have the GH1, and it's...

    Just downloaded a GM5 'Advanced Manual' and found the following on Page 167 :-

  • OK, Thanks for the info... So it's looking like I won't be limited to the eShutter after all. Could I ask a you a favor to ensure this is the case?

    A really easy way to tell, would be to fire off...

  • I just done a quick search and all I can find is someone saying it's not possible to use mechanical shutter with legacy lenses on the GM1 - Not found any info on the GM5...

  • Hi Again Samuel,

    Hmm... No I did not realize that. It's not so much the 10bit depth that concerns me, but the 'Jello' that would be apparent on all action shots. (As from what I've read, the...

  • Hi Samuel,

    I remember an Engineer explaining to me once, that the GPS system needed 3 sats to be visible for a minimum of 45 secs to get a lock. (I've no idea if he was correct or not).

    My smart...

  • I must confess, I would be one of those who switched it off!
    Although I understand it's nice to have, the reality seems (to me) to be different. Not only does it drain the (limited) battery - but...

  • Excellent... I'm thinking with the EVF off, it will draw very little current - so auto switch off 1 min is probably not an issue.

    Also 6x mag seems good enough to me... looking like the credit...

  • Hi, I have a couple of questions on the GM5, that I was unable to find in the User Manual...

    1. Is it possible to turn off the LCD and set the EVF to only turn on, when you put your eye to the...

  • Nice catch! I prefer the third shot (not as it's B&W), but because it shows the surroundings a bit better and I like the angle of the VW. Reminds me of an article I read on the net... http://www.da ...
  • It's tricky to use, but have a look at IRIS (Freeware for Astrophotography)... http://www.astrosurf.com/buil/us/iris/iris.htm You will need to get a 'Point Spread Function' though, so it's only ...
  • My very first camera (a Kodak 126) only took 24 shots, but I would not limt myself to just one film over 2 weeks. Yep, I had a Sunny or Cloudy setting :-) or for indoors a flash cube. (if it would ...
  • Hi, How long does it take to focus?? My Tamron 18-250 (earlier version of yours) takes about 1/2 a second to focus (worst case i.e. from closest focus to infinity). A typical time (say 20ft to ...
  • Hi Paul, The problem I had was the opposite, i.e. infinity focus was not achievable. However (depending on the adapter) it can be quite common for infinity to be at the 'x' meter mark. Personally I ...
  • Your problem is that the exposure was way too short. However if you have dozens of RAW shots and you can just about see the moon in some of them, then there is a good chance you can do something ...
