Many of the photos are comparing the horizontal Think Tank UD50 with the new vertical Think Tank UD35. The lens being used to compare sizes is the Canon EF 70-200 f4 IS lens with the hood on The UD35 is an absolute perfect fit for a 13" Macbook but take notice if you use a pro SLR or a battery grip, you'll need to adjust the dividers leaving room for only a 10" laptop. This also introduces the requirement to remove the camera, before the laptop. It will hold almost everything the UD50 will hold but with the one difference on how accessible items are. How difficult it is to access items at the bottom will depend on how you setup the dividers. ThinkTank seems to ship more then enough extra custom dividers with the products I have purchased to date. The UD35 only has one SLR fold out pouch instead of two in the front. This is something I personally have never used but the extra space is there if I ever needed it.
What works
Well built, Lots of room, Comfortable to carry
Room for improvement
Very Little. Some may find the pockets too narrow.
