I really want to do my research on the next lense that we purchase. I know this iswrong, but i honestly do not want to rent a lense to test it out. I keep thinking, why rent and "waste" the money. I wish there was and option to rent a lense and if you like it, you can put that money towards the buying of the lense. (no need to scold, i know...i know rent the lense)


My question is... when using alense with an aperture off2.8 how much of a difference is that say using aprime lense with a aperture of f1.4 ?? Is there really much of a noticable difference in low light situations?


I know, i know...just rent the lense.


thanks
