Both on my list, but not for the immediate future. Got a loan offer for the 150-500, will probably purchase the 50-500 new. However, such long lenses are quite a nightmare to test <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='
' /> I currently have no option to measure resolution of such long lenses indoors. Testing outdoors means I will have to wait for days with almost no wind, low temperature and most preferably overcast sky (so I can setup my own light). During summer, the temperatures are usually too high (resulting in shimmering air), so this narrows the test timeframe down to early spring or late autumn.
However, there might be an indoor option available, too, I'm just not sure, yet.
In any case: I will most likely test those two on FX only.
