Since RSA is an design "artifact", if your sample doesn't show it, others should be OK as well <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' /> But it could be this "dip" - most other sites test RSA in the lens center, where resolution shod be highest, hence the FS effect more visible...Anyway - that's good news, I can't afford the 24/1.4 ATM and it's too wide (for me) for shooting ppl - so if it shows good characteristic in your test and doesn't have FS, then it's on my "to buy" list <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />
