I have the Nikkor E 50/1.8 in Blooms article, it\'s tempting to use just for pancakes and the reduced mount thickness, but @ the price listed, I\'ll wait till a FF EVIL is released first, then the price should come down.
The speed boost would be interesting with my Rokkor 58/1.2
Re: IQ, I would need to see a (24mp FF) vs a (24mp APS-C + speed booster) shootout
before I\'d buy one.
