Hello good I have a 500d with sigma 18-200 lens and I'm looking for something comfortable if not a backpack bags or some kind of bag, I hope your help thanks. That does not depend on the camera depends on the lenses and accessories you have or want to carry. I care and I wear lightweight lowepro slingshot buy the Model 102 and I'm happy, this well thought out and is comfortable (no problem takes an hour and a half walk from there begins amolestar). Capacity of 500 with the 15-85 but the flash or other objective if they are not very big . . batteries and filters chorradillas dems . . It depends on qu ready to use. I have a Tamrac backpack to carry the material on travel, but I use it and end incmoda haca I usually use two bags Curmpler a slo Smallest if I take the 17 - 50 ms and a large if I take more goals, gorillapod . . I prefer the bags because I think mscmodas and safe. Well, as I say at the end almost tendrs to buy both: Pequea bag for times when you take it slo justito and a backpack bags to other times where you need to carry more material. Valverde_del_Fresno is west, between Portugal and Salamanca, and to the east and south by Elias and San Martín de Trevejo Portugus whole territory boundary with the municipality belongs to the "Natural Reserve of Sierra de Malcata. " Each village has its propia. Valverde Language of Fresno is under one of the least polluted atmospheres lumnicas Europe, being well known place for astronomical observations. The Pequea use it when I have to go ALGN site and do not want to carry all the equipment, I carry strap cargadita (500D + 55-250, 18-55, 50, Flash 270 E) that if a peln upset with a lot of weight above 2 kg starts charging back, I have intention to catch a bag with 2 handles. Yet another design is comfortable and fits the 500d + 18-55, a flash (Sunpack pz42x), it is space for another goal as the 55-200, charger and batteries. , But neither is q has a lot of equipment, in the time you have more things I buy a bag and leave it for when this does not want to be loaded. Lowepro Topload also a bag 50 where the 500 fits me with the 15-85 and put the hood, not folded, extended. You can bring a case for a separate purpose is hanging over the side. thank you very much for all the truth is that the end is what I thought of when I have one camera with lens so as conprare a fence extending pequeaya accessories buy a backpack bags to touch me again thank you very much. After having a bag CABA case logic where only the camera and stepped on, decided to buy the Lowepro Fastpack 250 and now it is the sigma 50-200 canon 50mm 1. 8, flash zeykos (half dodgy but it works) and my wireless trigger flash pt-04 The only thing wrong is that no tripod holder. The Pequea for when I go out for a walk with my girls and the bag when I'm "seriously" with the whole team. . . .
