#5d mark iii vs 6d mark ii low light iso#

That means your -7 EV is really -2 EV (and in fact, the 6D is spec'd to AF at -3 EV, but of course, that may not equate to real world numbers). Technically, your '0' EV is actually EV = 5.

#5d mark iii vs 6d mark ii low light iso#

Makes no sense.Ġ EV has a real, absolute definition - an exposure of 1 s, f/1.0, ISO 100. It's like saying you're going to start counting everything from the number 4, so if there are of 2 of something on a table, you're telling everyone there are 6. You're adding a lot of confusion here by arbitrarily defining your own zero. While I certainly wish there were more cross type focus points on the 6D, I think that with the low light focusing and relatively low ISO noise, the Canon 6D is going to be a very solid performer in low light situations. (When I initially heard the specs I was seriously underwhelmed). The more I play around with the 6D, the more pleasantly surprised I am with it. The 5Diii's & 6D's feel like there is a 2 step process to the focusing. The 5Dii, actually did very, very well in 0-> -3EV range. The Nikon D600 and 5Dii's Central focus points felt much quicker, and snappy.

While the Canon 6D's other focusing points are not nearly as impressive as the other focusing points on the 5Diii and Nikon D600, the 6D's center point is in fact very, very good in low light. I also tested the top center, and far right center focus points. (Note: Here '0' EV was an even exposure at 1/60, 2.8 ISO 400).įor those of you interested in the methodology and actual testing, as well as the specific results, you will want to check out my blog article on the test. I did some more tests today with the Canon 6D, and one question I was most interested in was the low light ability of the Canon 6D's central focusing point.īetween 0 -> -3EV, the Nikon D600 is about 10-15% faster than all of the Canons.īetween 0 -> -7EV, the Canon 6D is almost twice as fast as the 5Dii, ~20% faster than the 5Diii, and the Nikon D600 couldn't achieve any focus at all in extreme low light without it's AF illuminator.
