Hey I hope everyone has been having a good new year! So, recently (just yesterday) I shot some photos for an event with my 5D Mark II and my 50mm f/1.4 camera and lens. The photos came out alright, (some were very grainy, others weren't all so grainy). The lighting situation wasn't that good because I was forced to shoot photos in 6400 ISO with the aperture at 1.6 so I was able to get at least shutter speeds of 1/60 -1/80. However, at a later point, the room became black and people began to dance. This is where I kind of felt I needed a flash more than anything. My 5D with the 50mm wasn't able to even take a picture. Fortunately, I was able to turn to my T3 and use it with its internal flash to get some photos. Luckily, in the end with some post editing (since I always shoot RAW) I was able to make the shots somewhat decent. Furthermore, this got me some practice because it was a family event so I wasn't "hired." Regardless I try to do my best. Anyways, (sorry for the long story), I'm thinking of buying a flash really soon because I do want to start shooting indoor events, etc. Any suggestions for flash? I've been looking at the 430EX II and the 600EX-RT. Which ones would you all suggest and why? What does the 600EX offer that the 430 doesn't and would it really be worth the extra $200? Thank you once again for your replies in advance. Always great to get answers from this community!
