Hey everybody! I know I should be studying for my last 2 finals.. but my motivation is lacking a bit.. So I am packing my bags, and realized I need help deciding on what lenses to take to Las Vegas! Last time I went was when I was a kid back in 1989, so the only things I know about Vegas is from stories, pictures, TV & movies I'm staying at Mandalay Bay for 6 nights & I prefer to travel light, & do not want to take a separate camera bag, so space in my carry-on luggage is a bit limited.. As of right now, I'm packing my Manfrotto 732CY M-Y Carbon Tripod with 324RC2 Joystick Head, Olympus FL-BK01 Flash Bracket, Olympus FL-36R Flash and Orbis Ring Flash, which really doesn't leave me any space for extra stuff... I know for sure I am going to take my Rokinon 7.5 mm f/3.5 fisheye lens. I am deciding on taking 1 more lens, so for those who have recently been to Las Vegas please pick 1 for me! From all the lenses I have, I've narrowed it down to these 4 Panny 20/1.7 Olympus 45/1.8 Olympus OM 55/1.2 Olympus OM 28/2.8 Which one would you guys take??
