<p>70D? I thought the OP was going to use a 7D, which is excellent for this purpose.</p> <p>Modern cameras do not have focusing screens designed for MF work. Forget about even trying it with a current DSLR, for anything other than landscape and portraits.</p> <p>If you're going to invest in a lens, if you can afford it, get IS to maximize its functionality over a wide range of situations, including things like night street shooting.</p>

<p>By all means, try some panning shots, but they get old after a while. Leave IS on all the time, since it won't mess up a panning shot and has no ill effect if used when not needed.</p> <p>I always recommend springing for the IS because the 70-200mm lenses are wonderfully versatile and you'll want to use it in low light, for other subjects. It's a great street photography lens and ideal for portraits.</p> <p>If you had the luxury of a full bag of lenses, then you'd shoot some at ultra-wide, some with the 70-200mm and some with a super-telephoto. Each gives a unique perspective. If I could have only one lens for your proposed purpose, it'd be a 70-200mm. </p>

<p>The EF 70-200mm f/4L IS is a wonderful lens for bikers. It will NOT be too long for the subjects. Bikers are not that fast either. They follow a very predictable course and you'll have no trouble with focus if you use the AI Servo Mode.</p> <p>Unless you have a special purpose for an f/2.8, don't spend the extra money on such a heavy lens. </p> <p>Shoot at ISO 800 and around f/8 for good results. I tend to keep the EF 1.4x TC-III on my 70-200mm. Here's an example:</p> <p><a title="Damn photographer... by David Stephens, on Flickr" href=" src="https://farm8.staticflickr.com/7301/9585067054_3e01471408_c.jpg" alt="Damn photographer..." width="800" height="800" /></a></p>

<p>If you file jointly, it won't matter. Even if you file separately, I'd file on your Schedule C and forget about him.</p> <p>He has unlimited liability for your actions, unless you create a separate LLC or LLP. If either of you have significant assets outside this business, you'll want to look into some sort of Limited Liability entity to give your assets at least some protection against claims arising from business activities. At the very least, get a personal umbrella policy to cover you and your husband. That's only the first step toward protecting your assets, but it's important to have $1 million or so in coverage so that the insurance company will pay attorney fees to protect you and/or pay for a loss. (There can be business exclusions, so be certain what your policy will cover).</p>

<p>Since you have plenty of space, take both bodies, but work with the lighter one most of the time and pull out the 7D only if the situation warrants, or the other breaks. I wouldn't be surprised if the SL1 doesn't yield better IQ in certain situations, since its sensor is a couple of generations newer.</p>

<p>Many wonderful shots this week.</p> <p>Sorry for being late, but I was traveling yesterday.</p> <p><strong>Goldfinch Picks Apart Thistle</strong></p> <p><a title="Male Goldfinch Picks Thistle Apart by David Stephens, on Flickr" href=" src="https://farm4.staticflickr.com/3839/14600496892_9d06312cd6_c.jpg" alt="Male Goldfinch Picks Thistle Apart" width="800" height="800" /></a></p>

<p>My 7D and battery are five-years old and the Recharge Performance has been one Red block for almost two-years. I'd guess that you've got years to go before you need to replace your battery.</p>

<p>OTOH, in Chicago, wear a bullet proof vest...</p>

<p>I'm not sure how large the aperture is, but if it's f/2.8 or so, you'll only need to worry about things relatively close in the foreground. OTOH, at f/16, it'll focus close and out to infinity.</p>

<p>Thank you Robert. I appreciate you viewing my images and interpreting my "attitude" from my images and descriptions.</p> <p>I go by the guidelines in the thread heading. Fence posts are allowed, as are minor, incidental manmade elements. If that changes, I'll probably ignore it. The worst that can happen is that an image is removed from the thread. I'd suggest relaxing and enjoying the weekly treats that we see here.</p> <p>As a photographer, I'm not big into fungi, but I enjoy seeing it up close. Count me out if there's a fungi forum, but many others may greatly enjoy it. That's one of the beauties of Photo.net, we can satisfy many fetishes. </p>

<p>Robert, maybe you should read the guidelines again, at the head of the thread. They're not nearly so restrictive as you seem to imagine.</p>

<p>Yes Wouter, yes, I agree that we should agree to disagree.</p> <p>For those interested in learning more about DLO, try it for yourselves, particularly with your zoom lenses, like the OP in this thread. Digital Photo Professional includes DLO modules for most EF and EF-L lens/body combinations, so it'll cost you only a little time to see if you want to include it in your workflow.</p>

<p>Wouter said:</p> <blockquote> <p>David, what you call "digital distortions" are optical errors that for a large part are not due to digital at all, and occur similarly on film. Chromatic aberrations, distortion, vignetting - it all happens on film as well. It really has got zero to do with the recording medium in the camera. So you're whole point on how we should treat this differently on digital to level the playing field is, in my view, based on a complete misunderstanding. You make a distinction where there is none.</p> </blockquote> <p>Wouter, sorry if I was unclear. I don't think I said that CA and vignetting were digital distortions. Those are optical distortions. Purple fringing and moire are a couple of digital distortions that I mentioned that can be excited by optical distortions. I meant to distinguish one from the other. Of course, DLO corrects for both optical and digital distortions, some more successfully than others.</p>
