My experience with the 1.4x and 1.7x converter is that they are just fine with the old 300 f/4 and there are no big problems with noise, if you're starting with a good light (clearly, if you are already at the limit - e.g. shooting a wildbear at dusk - things change).

 

@Klaus I'm not an Eclipse fan, because I use NetBeans. In any case, it's open source too. It happens that 80/90% of Java developers use an open source IDE, so they don't find it so bad. And for what concerns bugs, I had a few bugs fixed in NetBeans, and other open source software, that I provided myself. They were accepted without many problems. It doesn't go always in this way, but it's way better than with closed software, where you can't ever think of making a contribution...
