does anybody own this bag? i have out grown my old lowerpro, and i needed a bigger bag to fit my camera and lenses in. i want to be able to fit my canon XSi,75-300 (attatched), and my 28-90 lens. i also wanna be able to fit in some lens hoods and filters, and of course my battery charger, chords, and manual. so do u think i would be ok with the medium (interior: 12" x 7.7" x 6.0")?
