I've been shooting photos/videos for weddings and commercial work for a few years now but have now made the jump into part time real estate photography. I've been very comfortable with my Canon T3i for shooting the events I listed previously. I have a Sigma 10-20mm Wide Angle lens for interior shots and pretty happy with the results (with the exception of some minor distortion, which might make me look at the Tokina 11-16mm).
My main question is this: Should I jump into full frame now that I have a more serious position with real estate photography? I'm so very content with the lenses I have for my crop sensor camera that it'd be painful to part with these and pay more for the higher quality lenses with equivalent focal length. By no means am I against it but with a T3i and lightroom for some wide angle lens correction, can I achieve close results to a full frame? All of this is for web use, so resolution isn't quite important. I'm just concerned about color depth and lens distortion.
Any help would be great and give me a little piece of mind in knowing if it's time for me to make the jump to FF at this point in my career. Thanks to anyone looking to help out a forum n00b!

And it doesnt help with flashes/strobes.
