Hi all, I have been wanting to get into photography for years and I recently took the plunge and got a Canon Rebel XS. Right now I only have the lens it came with, the 18-55mm. My budget is $400 and here are the finalists: Either the Canon EF 28-135 mm f/3.5-5.6 OR Both the EF-S 55-250 f/4.0-5.6 and the 50mm f/1.8 My main concerns are image quality/saturation/sharpness and versatility. (Don't care about plastic, aesthetics or noise) I have been online reading reviews for what seems like hours and am having trouble deciding if the 28-135mm is worth the extra money or if I would be better suited to buy both the 50mm and the 55-250mm since I am literally just learning how to use an SLR camera. Any advice, thoughts or opinions would be much appreciated. Just please don't tell me to save up to get an "L series"...the camera and this extra $400 for another lens is a big splurge and will not be able to consider a lens in that price range for a very long time, if ever. But I do want to get the best bang for my buck. THANKS!
