I got one for about that price only had about 9.5k actuations on it. But that doesn't drive the price... Especially if the seller isn't privy to that info. You can get software to check the actuation count AFTER you buy. Other than that, you're just counting on the seller to know what they're talking about.
This is a question that you should ask the specific seller under the specific listing that you're viewing.
I purchased the body only because I owned lenses already. The camera is often offered and priced with the 24-105 f/4. You need to look at the offering options and compare the prices of body only with those that offer a lens combo.
I recommend you choose an listing from Amazon directly or one that offers prime benefits.
I don't know what listing you are looking at that includes more than one lens. Check the listing and ask the seller if you are not sure. I just reviewed the camera, I'm not the seller.
Not sure of what you're asking, shutter timing range or how many exposures it will automatically shoot in exposure bracketing, or what. Shutter timing ranges from 30 seconds to 1/8000th second. It brackets 3 exposures automatically. I believe this is the same as with the new 5D Mark III. Let me know if your question was something different. Glad to help. TED
