first, be wary. The internet is overloading with stories of family members with good intentions doing just what you did and ruining their relationships. They SAY they don't expect much but I'm sure that subconsciously they imagine a fantastic leather-bound book full of 10000$ images.
second, you will not be enjoying the day if you spend it shooting.
That being said, you can still do it. Just do your homework, practice, and make more than sure that things stand clear with your brother and his girlfriend (especially her).
Originally posted by Kouwen My problem is this, I want to get a lens with some reach. I have been reading up on the DA 50-135, sigma 50-150, the Tammy's etc. I just don't know what to get. I read that the Tammy 28-75 f/2.8 is really good but to me it seems way to short. I like to zoom a bit, I don't want to stand in front of everyones nose etc
If you don't want to stand in the way, 100mm is usually a good focal length. Especially since you already have a good 35mm. The 50-135 is generally regarded as the best lens for weddings. I'd consider it.
Originally posted by Kouwen The wedding will be indoors so I do realize that I need a flash as well. Which one?? I read that the Pentax TTL sucks?? really?
PTTL is not as complex or complete as Nikon's system, but it works. And in any case, inside a wedding venue light will be constant, so your best bet for faster operation would be to set everything in manual beforehand.
the cheapest, most powerful flash ith decent functions is the Sigma 610 super. I'm currently using the Metz 52 AF-1 and I love its small size and how it operates. It's better built too. The Pentax AF540 (version 1 or 2) is a great, full-featured flash but it's expensive. If you want to go manual, I'd recommend looking at the 100$ Godox V850 (called Neewer TT850 on Amazon). It has the best recycle speed ever because of its Li-ion battery, and will give you 3-4 times more flash pops than an AA powered flash. Plus it's very powerful.
One thing you might want to do with your flash is bounce it on a white surface. That can be a reflector, a friend's white shirt, etc. Don't bounce if the roof is too high.
More than anything else, practice and erad before shooting. Do that a lot. Go to the venue, with the bride and groom, take test shots, see what they want, what they have in mind, etc.
Good luck.
