Wow! I just want to say that my inner engineer geek and photographer geek are really having a blast reading this thread! I know enough to follow the concepts but I also know when my understanding isn't solid yet. When I have more time I'm going to read it through at least once or twice more! This thread is why I stick with the CR forum! The in-depth information I'm seeing and back & forth discussion are riveting.
Thanks so much for putting so much effort and time into this (and many other threads). I'm sure some are reading this and saying, "Who Cares?" but not me. I'm seriously geeking out here.
My comments on the thread so far are...
- While I understand what neuro
are saying about DR, I agree with MichaelHodges
in that DR carries more significance. At least for me it does for some of the same reasons he states. I bristled a bit when I read jrista's DR opinions. Of course, I'm not shooting wildlife as often as I'm shooting boy life (scouts running around, etc) but the same factors apply, except I probably won't be killed!
- I've read things in the past about lens resolution vs. sensor resolution and while some of the discussions seemed to have a lot of evidence and facts to back up the theory, my gut has never believed it. Good glass is good glass and if it was good enough to produce a beautiful image on film in the '90's, it should still be good enough to produce a beautiful image on a sensor in 2010. The light, the glass and the sensor don't know when the lens was made, they just do their thing. If the glass is clean, aligned correctly and focused properly, the image should be sharp. If a newer technology lens uses better glass, coatings and IS so there is less light corruption then the picture should improve from those upgrades but not because the resolution of the sensor "matches" the resolution of the lens. This idea has never sat well with me.
, the techniques you are using on the the moon to get sharper images, etc are impressive. I'm really enjoying reading about some of the tricks and gear you are using to do it. I've always struggled with explaining to newbies why it is hard to photograph the moon with the gear they have when they can see the moon clearly with their eyes. I've explained a lot of the obvious stuff but you take it to whole other level! Wow!!
