Hi, The 2.8 is heavier than the 4.0. One of my favorite pro photographers that has an outdoor photography show on PBS recently went to the 4.0 from the 2.8 as he felt the 2.8 was too heavy. I use the 2.8 to photograph my grandkids high school sports as I need the extra speed but I have it a monopod making the weight almost a non-issue. You might try that as I really like the 2.8 but you'll have to make up you're own mind. Good luck, and keep shootin'. Mike

Hi, Tamron's 60mm is a great buy right now from Adorama or B&H (check them both). It is a good price with a $100.00 rebate which is within your current range. It is a great lens and an excellent buy. Check it out. Keep shootin' Mike

Hi, If you want to shoot sports you need a 2.8 or faster lens as it is tough enough to get good action shots w/o handicapping yourself with a slow lens. Good luck, Mike

Hi, I'm an old technologically handicapped guy that has no idea how to post pictures. Sorry. Keep shooting. Mike

Hi, If you always check reseller ratings you will save yourself a ton of trouble. Also Adorama and B&H are truly reputable firms and will always help you. Good luck and keep shooting. Mike
