I think the 40D will be okay for weddings. It is a semi-pro model with better build than entry. I have the 28-135 which is good, but I'm not sure how it would hold up when the results have to be scrutinized after. I would highly suggest not buying it from a retail store though. There are so many mark-ups now, the internet is where you can find bargains. Careful reading about returns and warranties will really help if you're worried about getting a defective camera...
At the level you're at, why not stick with what you already have? Oly glass is pretty good. If you invest in a couple of Canons or Nikons, you're going to need some pro glass and be thinking of spending some money..
I wouldn't shoot weddings for the world, but I have a number for friends that do. One shoots Nikon and leaves a 17-35 f2.8 on one camera at all times. The other camera usually gets an 85 F1.4 prime. You're looking at over $2500 in lenses and nearly $10,000 in two bodies, not to mention pocket wizards, tripods and lighting..
With Oly, you're probably going to have to invest in the excellent 7-14 superwide as well as maybe a 14-54, I don't know..
Just my thoughts...
Wedding with only one lens like the 28-135..
I recently attended a wedding where the "hired" photographer shot the entire wedding with a Rebel Xt, with the 18-55 kit lens and a flash on a bracket..
I felt sorry for the bride (a friend of my wife's) knowing what she was going to get. I saw him "try" and take photos of them dancing. He might of got 2 or 3 shots off during the 5 minute dance. Sad, really..
I own a 40D, 24-105 and 70-200/2.8 and know what it takes to get good low light shots, nice background seperation and other photographic qualities that seperate DSLRs from P&Ss..
Considering you already have Oly gear, you would be better off getting an E3 or using what you would spend on a new camera and putting it towards lenses more appropriate for your type of shooting..
Not knowing what you're using now (although from the comment on the 28-135, I'll guess you're using the kit lenses) I would get a Sigma 30/1.4 or the Leica 25/1.4 if you can afford the latter..
Probably the 35-100/2 zoom, if not then either the 50-200 or the soon to be released for Oly Sigma 70-200/2.8..
Maybe the 50/2. At the very least the 14-54..
Despite what some say, equipment is nearly as important as the photographer in many situations..
Evaluate how you want to progress your business to the next level and commit to purchasing the equipment to take you there..
Waste of money, but nothing wrong with the quality..
You'll do just as well with a Reb el XTi, and you can spend the money you save on a decent lens, such as the Siigma 18-500mm f2.8, a flash gun like the 580EX, a Canon off camera shoe cord 3, a second flash gun like a 430EX, a couple of light stands, and a backup body, such as a Rebel XT if you can find one that's new..
Only the terminally unstable try to be a wedding photographer without a decent backup camera and flash gun..
Fast lenses would be a better investment..
If you are going to switch systems do it before you get the expensive lenses...
Thanks for all the advice....
About the change of system, should I switch now before it's too late or should I stick withe the E510 / E410. Will they do good with a lens like that:.
Or should I get the cannon which is better camera to begin with (6fps is something that sounds awsome) but then the kit lens is subpar for what I will do..
Ok, what are you thinking? Everyone says that the camera doesn't matter much. The frames per second don't matter so much. What are you considering a 50-200 for? That's a field of view of 100-400mm in 35 for 4/3 mount. Are you planning bird photography or weddings? The 50mm end might make a long protrait lens, maybe..
If you are really attempting wedding photography, you need to be looking at a good wide for general use and a good portrait lens. Oly makes them. You're also going to need good lighting, umbrellas, wizards, tripods, L-bracket, flash brackets and such...

Well if I knew those things I would not be here asking....
So those 2 would do? if someone can point me to others that are better price/quality (in the same price range) that would be great.
