Indeed, the manual for my 7D Mk II states that GPS does function when the camera is off and can affect battery life. However, if you aren’t using this function, GPS can be disabled. I haven’t really tested to see if my Mk II has reduced battery life compared to my original 7D (and can’t anymore since the 7D was sold some time ago), but I use it pretty heavily at airshows and have never felt limited by battery life. And I use a mix of new LP-E6n batteries that came with the camera, and some leftover spare E6 batteries.

I've got the Neewer off of Ebay. As mentioned above, it's cheap and it works. Be sure to get the one that fits your camera model.

Bought this lens (Amazon had the Bower priced a lot less, for some reason) for astrophotography. Great lens for it! Can't beat the price. Glad I bought it.

EF-S lenses won't mount on a 6D. Is it a 60D maybe? If it is indeed a 6D, then the 24-105 f/4 L will be perfect. If you're looking for the 24-105 f/4 L, check your local craigslist. That lens was commonly offered as part of a kit and a lot of them go up for sale that have never left the box. Otherwise, check out KEH camera for a used one.

I agree with Glen. For printing, large files are usually better and if printing large then they are a must. If uploading to a website, they are overkill and it takes more time to upload. And if the site has a size restriction they will have to be reduced or the site will resize it and that takes even more time.

<p>I know your game is over, but if you didn't get what you needed this time, perhaps this will help for the next game.<br /> <br /> I shoot Canon, not Nikon, but I assume that your camera has an Auto ISO feature. If it were me, and the priority was to get the shot no matter what, then I would start by setting my shutter speed according to the 1/focal length rule (maybe a little slower if that's an IS/VR lens) and set for auto ISO in shutter priority. If the sideline is fairly well lit, then the pictures shouldn't be too noisy. However, if it's not as well lit as you think it is, then noise may become objectionable. That should take care of camera shake, but if you're still getting blurred subjects then slowly take the shutter speed up until you get what you want. If the images are nice and clear then you can slow the shutter speed down a little and the camera will reduce the ISO (and the noise) automatically. Certainly your lens is not particularly fast so be prepared for some relatively high ISO settings, even though your eyes tell you there's plenty of light.<br /> <br /> With Canon, in this setting where it's kind of dark, the camera will almost always set the aperture to it's fastest available stop so I'm assuming your Nikon will as well. If you can use a monopod, then that will help assuming your blurry images are a result of camera shake and not subject movement. Take a look at the pictures you have already taken (the blurry ones) and see if the entire image is blurry (camera shake) or stationary objects in the image are sharp (subject motion).</p> <p>You might also make sure that there isn't something in the foreground (most common) or background that is sharp--that would mean that you aren't focusing on the subject you want. That can easily happen if you're using all of your focus points instead of just one or a few in the area of your subject. In addition to the settings above, I would set a single focus point or a small group of points.</p>

I have to agree. I use One Shot most of the time and AI Servo when I need it, but haven't found a use for AI Focus. I haven't even tried it on my 7D-II so I don't know if it's improved over earlier versions, but I never use it. And I too really miss ECF. I found it to be a really useful feature and just might buy the first camera to re-introduce it.

<p>Yes, the ML-3 can be used with that camera and will mount to that lens without the need for an adapter (according to the manual).</p>

<p>I've always used the cheapo Canon RC-1 and it works fine. If you just want it for vibration control (so you don't have to touch the camera) for long exposures, why not just use mirror lockup with the self timer? That works, too.</p>

Best part about Canon refurbished is a full one year warranty. I just bought a 7DmkII from them. There's always going to be a better deal tomorrow. If you want or need the camera, get it and stop watching prices.

<p>Check the little silver screws that retain your tri-pod collar when it's mounted. I bought a used 70-200 f/2.8L that was as you describe. Turns out one of those three screws had backed out and was loose. Once it was tightened, that solved the problem. All of my other lenses with tri-pod collars have always been smooth.</p>

<p>If you have Canon lenses, then check to see if they are marked as EF or EF-S. Your Rebel camera can use all of Canon's EOS lenses and as long as you get another Rebel or a camera with a APS-C sensor (60D, 70D, 7D, 7DII), you can use any of the lenses you are currently using with your Rebel. However, if your lenses are marked as EF-S lenses (and I suspect as least some of them probably are), then they will not be usable on any of Canon's full frame sensor cameras (1DX, 5DII, 5DIII, 6D). EF lenses have a red dot for alignment when mounting and EF-S lenses have a white square. Tamron and Sigma both have designations for crop sensor only lenses (Di-II for Tamron and DC for Sigma) and likewise these lenses shouldn't be used on a full frame camera.</p> <p>Almost all of Canon's current cameras will be much better in low light than your XSi. I believe the 7DmkII is the current top performer among Canon's lineup for lower light performance in an APS-C sensor. However, if you really need the best low light performance, you'll have to move to a full frame camera where performance is usually considerably better. </p>

Just to rule it out, have you tried it without the filter?

The Rokinon lens is very good for night sky photography. I have the Bower branded lens (from what I understand, same lens made in the same production facility but Amazon had it cheaper than the Rokinon) and I bought it for the same purpose. Got a chance to use it a couple weeks ago when I took a trip far enough away from city lights. I was very happy with the results. For the price, it's a real gem!

<p>I have bought from KEH before and I've been generally satisfied with them. As far as what's included (camera strap, manual, body cap), that varies from item to item--probably because that's the way they bought the item. It is common for them to list multiple copies of the same item with different things included (for lenses some of them come with a hood, some with a carrying case, some with both and some with caps only). Usually, it's a few bucks cheaper when fewer extra items are included.</p>
