Quite right.. to qualify as artistic and creative, your shots must be as technically sharp as possible. Toward that end, you really should always shoot with top of the line primes and always stop down a couple stops from wide open.
When done well, there are great images to be made with the possibilities offered by lensbabies. Have a look at their own gallery: http://lensbaby.com/gallery-photo.php

I suppose it is good that people like different things but personaslly - definiterly not for me.
Years ago - if a lens was poor in quality - we tended to refer to it disparingly as a "f2.8 Tizer" - referring to the bottle glass used to house Tizer fizzy drink - and a play on the reference to the excellent Zeiss optic, the f2.8 Tessar.
To me - sorry - but that's the f2.8 Tizer syndrome.
However, I am sure there are plenty of would-be "creative" photographers out there who will rush to buy one.-- hide signature --

"A photograph is usually looked at - seldom looked into." "A good photograph is knowing where to stand." "Sometimes I do get to places just when God's ready to have somebody click the shutter."
