First up, this thread is not about whether or not you would buy one, or if like them or not, we've been there and done that before. BTW This thread was inspired by a post at Photography Life The Question of 18-300mm Lenses, Part Deux
While modern cameras resolution pushes the optical ability of super zoom lenses, I am often left wondering what I would do if I was going on the trip of a life time with extreme weight restrictions, or if I had to downsize my camera bag due to economic or heatlh reasons. I know some people might say, "if I could only have one lens, it would be a 50mm (or this or that prime)", but we all know that depends on a persons style. I'm not looking for a, "this is my favourite lens" , or "this is the best in this range, so just crop to get what you want" post here. This is a therietical, would you use a super zoom under x conditions question (see conditions below).
Lets take the author of the articles ending statement (he says if he was trapped in a desert with only one lens, it would be his super zoom) to the next level, of a once in a life time trip/assignment. Remember, for this scenario getting the images you want/need are more important than whether the lens used would give the best possible resolution on a test chart. You won't be putting these images on a billboard, or making 24x36+" prints. The images will be presented either on a projector (1080p), or on smallish prints (8x10 or around that size). You can only carry a smallish kit, and your camera equipment cannot weigh more than 2000g (including camera, lens(es), batteries, cards, chargers, bag), but you need to cover the focal lengths provided by a super zoom (18-200/18-300/28-300mm). You also need to be able to switch the zoom range often, due to the speed in which you have to move/travel during the shoot.
So what would you do?
A) Suck it up and take the super zoom
Take a light weight two lens kit, DX 18-55mm VR and 55-300mm VR / or FX 24-85mm VR and 70-300mm VR
C) Another light weight lens combination that would fit these requirements (list what you would take, and how much the kit would weigh so we know it fits the requirements).
I know some might say, "I'll take a mirrorless camera setup, my take a crop sensor fixed lens Fuji/Nikon/Ricoh and crop the images later, or a high quality super zoom point and shoot (aka Sony RX10)". Let's just leave that off the table for the sake of this discussion. Focus on what you would do, if you had to take a DSLR, with the listed conditions.
Okay, let the craziness proceed!
If I take a good photo it's not my camera's fault.
