After having a proper think and a ponder, I've decided to go for a portrait ish lens i think. like the oly 45mm 1.8 or either the 30 or 60 dn 2.8 . Main purpose for lens... take some better shots of the family Better shots at gigs. I'm a wedding DJ and I take load of pictures of the dancefloor at the events I do for the client to then share on FB etc For example https://www.facebook.com/media/set/?set=a.683124171738419.1073741902.245461488838025&type=1 I use my 14mm for the uplighting pictures. no issues changing lens after that. I do use my flash gun for gigs, not really experimented for the family shots yet. My head seems to think the oly as It has the extra f so in theory should be easier to take low light pictures and a little wider for dance floor shots. The sigma new comes in at the price of the oly 2nd hand. One of the problems I find is that there doesn't seem to be a bad lens out there. Soon as I see someone using or recommend a particular lens somewhere, I do a google search look around and every lens seems to come in at 4/4.5/5 star rating, with lots of positives. Makes it hard for novice like me to know where to spend my hard earned readies. So over to you guys, I'm really talking entry level here (not pro £££), that I can use and why you would recommend it. It's going on a Pana G2, I have the Pana 14mm 2.8, and the Pana14-45. Am I right for trying to get a lens to do both? As the 2 main reasons for buying are above, what options would you go with regards, budget, and what I already have? Your thoughts & opinions are most welcome Cheers, David.
