Also if you live in an area that doesn't really cater to your photographic needs...Renting a new camera body, lens, tripod or whatever before purchasing is a fantastic way to see if the equipment you are interested in actually is what you want......That is WAAAAAAAAY better than buy from a dealer to only have to return it and wait for a refund.....after a while the retailers catch on and will no longer allow you to purchase and return stuff if you do it frequently...so RENT from BORROW LENSES.............
What if you need a Tilt Shift lens for a single job.....why buy that puppy when you can rent from BORROW LENSES and save some money and make more profit.....
Or you are going on a trip of a life time....maybe an African Safari....and you need a 600mm lens or a great zoom like a 200-400mm zoom lens but you have never needed one until now.....want to fork out several thousand dollars....if you don't think you will need it once a month from then on then RENT It.....Nikon 600mm for 4 weeks a little over $1300.00 as opposed to a purchase of approx.......$5K to 7.9K Or more to get the winning bid USED on Ebay......or new from approx $9800 to 14K.
BORROW LENSES is the way to go..............
