I will definately be getting the 50mm, why not for £80? just need to consider the other options thank you.
Why not?....
- because the AF is fussy and unreliable and may let you down in the exact lighting situations for which you bought an f/1.8 lens in the first place;
- because the AF is noisey and may be obtrusive during a wedding ceremony;
- because MF is very difficult to achieve with precision as the AF gearing mechanism does not disengage and thus seems to fight you, even if you are not attempting to AF. Also the MF ring is added almost as an afterthought, seemingly not intended to be used in all seriousness;
- because when stopped down the pentagonal bokeh is pretty unattractive;
- because the build quality is poor and it will not take knocks well.
I speak from experience. I used to own the 50/1.8, barely used, it for the reasons stated, and replaced it with the 50/1.4. The 50/1.4 has its faults as well, but for weddings it is certainly a few steps ahead of the 50/1.8.
You should find some 50/1.8 (nifty fifty) love/hate threads over on POTN (
example thread,
and another) if you want to delve deeper. It's a great lens for newbies progressing beyond the old 18-55 kit lens and wanting to see what fast glass and shallow DOF looks like, but I would not rely on it to deliver sharp results time after time during a pro gig when the pace of events (e.g. during the service) will not wait for the photographer to get the focus right. If you have the luxury of time to get the focus right then the lens does offer good VFM, but just be aware of the limitations for more serious engagements.
