<p>The 7D is not especially beginner friendly for video. I used to own one. Have you considered renting something like a Panasonic GH4 instead?</p>

<p>I have a major electricity company in Jamaica asking me to take some technical photos for them. I am strictly an amateur, but a professional friend of mine referred them to me because they needed someone with long glass to take detailed photos of wind turbines. I am looking at about 6 hours of travel time and 2 hours of work. Would 500-600 dollars be a reasonable charge? They offered me 200 but that seemed awfully lowball to me based off the distance I would be driving and I told them I would not do the job for that. They are waiting for my counter offer. <br> My justifications are as follows:<br> 8 hours of my time <br> Price of gas in Jamaica (8 dollars a gallon). Based off the distance I'd be driving I am guessing I would spend about 60-70 dollars on gas.<br> High risk location (poor security)<br> The fact no other local photographer has a Canon 600mm lens and a teleconverter.<br> Thanks for any input!</p>

<p>I recently bought a Tamron 24-70 VC. The lens is wonderful and autofocus is very accurate through the viewfinder. However, in live view mode it fails to lock focus under any condition on my 5DS. Has anyone run into this issue? Sadly my lens is gray market so I do not think I can send it to Tamron for servicing.</p>

<p>I use 3rd party batteries, but the only brand I really trust is Wasabi.<br> I've tried a few third party battery grips on various cameras (40D, 7D, 5Ds). I ended up returning them all and going first party.</p>

<p>I use <a href="http://www.ryanjosephphotography.com">500px</a> with a custom domain. </p>

<p>I used to shoot both, but over time I managed to get rid of film from my workflow. If you are willing to put up with the difficulties and cost of shooting film, my favorite film is Kodak Ektar 100.</p>

<p>I always travel with two lenses. A 24-105 and a 100-400. I find that between these two lenses I get 99 percent of my needs covered. If I could only take one, it would probably be the 24-105.</p>

<p>Sadly I sold my 7D so I no longer have a body to test the lens on other than my 5DS. I have a friend with a 60D I could try it on though. Using DOF preview shows the aperture works fine, with no signs of sticking as far as I can tell. I am getting perplexed by this underexposure problem.</p>

<p>Yes it happens in AV mode. Here is a link to an example photo being underexposed. </p> <p>https://d199bk7kirt65b.cloudfront.net/files/p/E~forums/56327767/3d4d8ce7e9164d26ad8e619369f2b90a</p>

<p>Recently picked up a Canon 100mm (older non-USM) macro on the cheap and was testing it on some bees yesterday. I noticed as I got closer and closer to subjects that the camera would tend to underexpose, not accounting for light loss in macro range. Is this related to the age of the lens? I seem to lose about two stops at 1:1. I don't mind doing exposure compensation, but I just assumed the camera would compensate for macro range photos itself. Thanks for any input. </p>

<p>I think sensor size will always matter. Just like cars, there is no replacement for displacement. Larger sensors produce better images. Go to Imaging Resource's Comparometer and compare two cameras with different sensor sizes but the same resolution: the 7D MKII vs the 6D. At all ISOs the image quality from the 6D is noticeably better than the 7D. </p>

<p>Ended up buying the 100mm macro and love it, thanks for the input.</p>

<p>I never considered the lack of parts. Then again I am in that boat now with the Phoenix macro.</p>

<p>I am acquainted with somebody that is selling the Canon 100mm F2.8 Macro Non-USM. He wants 150 dollars for it. The lens is in mint condition and everything checks out on it. The price seems right but I am still on the fence about buying such an old lens. According to what I read on the internet it's image quality should be comparable with the USM model. When I work in macro I usually manual focus, so the lack of USM doesn't seem to be that big of a drawback to me.<br> I would be upgrading from a Phoenix 100mm F3.5 Macro with a matched diopter, which I can sell for about 100 USD. If I sell the Phoenix I would basically only be out 50 bucks buying the Canon lens. Thanks for any thoughts.</p>
