Most folks disagreed but I was still sure that with a 7D II, and more recently with the 5DS R, that one had better keep the lens perfectly still in order to create sharp images.  <\/p>\n<p>As it turns out, it looks as if I was both wrong and right. Right about my gut feeling that lens shake was more of a factor with both the 7D II and the 5DS R than with previous camera bodies, and wrong about the reason. Below are selected quotes from an e-mail from good friend and many multiple IPT veteran Alan Lillich.<\/p>\n<p>First a definition. Pixel pitch the distance from the center of one pixel to the center of the next pixel measured in microns, millionths of a millimeter.<\/p>\n<p><em>Here is my take, derived from basic principles. Remember that pixel pitch is just the spacing of the pixels. All of my body-to-body comparisons assume the same lens&#8211;side by side, the same aperture and shutter speed, at the same subject distance. The visibility of shake is measured by viewing at 100%, looking at the sharpness of the finest subject details.<\/p>\n<p>With a given camera body, lens, tripod,tripod head, wind, shutter speed, and level of operator skill there will be a certain amount of shake during the exposure. Physically this shake means the image moves across the sensor during the exposure. How much it moves is a just a distance. How visible it is depends on the pixel spacing. (And probably on the AA filter, Bharat\u2019s comment in the previous post on this subject is interesting.) I have no idea what the actual shake amount is in any situation, nor exactly how much the AA filter (on all the bodies but the 5DS R) smears things. We do know the pixel spacing for specific bodies, but for this discussion all that matters is the ratio of shake to pixel spacing.<\/p>\n<p>If the shake is less than the distance between pixels then it will be invisible. The more pixels it covers, the more visible it is. It is hard to compare given the span of time and changes like the improvements in IS with the Series II super-telephotos. With each new camera the same sensor size with more pixels means tighter pixel spacing (smaller pixel pitch); the same shake will cover more pixels and be more visible.<\/p>\n<p>Let\u2019s compare the 7D II to the 1D IV. The 7D II has a pixel pitch of 4.1 microns, the 1D IV has a pixel pitch of 5.7 microns. So a 12 micron shake would cover about 3 pixels on a 7D II and about 2 pixels on the 1D IV. In other words, the shake should be 50% more visible on the 7D II than on the 1D IV. You have to be that much more careful with the 7D II than with the 1D IV.<\/p>\n<p>The 5DS and the 5DS R have a pixel pitch of 4.14 microns. I\u2019m getting these numbers from quick web searches. So I\u2019m confident they are accurate, but don\u2019t know how precise. The 7D II number I saw was just 4.1, with no hundredths digit. Let\u2019s just say the 7D II and 5DS have the same pixel pitch. So the 12 micron shake mentioned above would also cover 3 pixels on the 5DS and the shake has the same effect as on the 7D II. So you need to use the same care with the 7DF II and the 5DS.<\/p>\n<p>Again, this is with same lens, side by side, same subject. Another way to look at this, especially relevant to 100% examination, is the effect on subject detail. The projected image on the sensor has a size determined by the lens and subject distance. A bird\u2019s eye or feather details will be a certain physical size on the sensor. So a certain amount of shake will affect a certain fraction of the most detailed features. How visible those features are depends on the pixel size.<\/p>\n<p>Now let&#8217;s consider the anti-aliasing (AA) filter on all cameras but the 5DS R. As Bharat\u2019s comment pointed out, it blurs things so will hide some degree of shake. <\/p>\n<p>What this means is that you need more care with a 5DS R than with a 5DS or 7D II.<\/p>\n<p>Bottom line, better technique will get you better photos in general. The smaller the pixels and the tighter the pixel pitch, the better technique you need. Pixel count alone is not relevant. All of this of course in a theoretical same lens side by side situation. Suppose you and I are sitting side by side on the lower shelf at the Cave Store cliffs shooting tight portraits of pelicans. We have the same lens, but you have a 5DS and I have a 7D II. You can\u2019t get closer without scaring the birds, I can\u2019t move back because of the cliff. So we can\u2019t get the same framing but do get the same pixel coverage of subject features. So we need equal technique for equal sharpness as seen at 100%. With you owning and using the 5DS R, you actually need to take a bit more care as there is no AA filter to blur the effects of lens shake. <\/p>\n<p>Though you many not previously have understood all the technical stuff above, I think you have grasped all of it inherently given the magic you do with super-telephoto lenses used with either teleconverter at slow shutter speeds&#8230; <\/p>\n<p><\/em><\/p>\n<h3>So Yeah&#8230;<\/h3>\n<p>So yeah, when working with the 5DS R at long effective focal lengths, I do need to take extra care in order to create super sharp images. With today&#8217;s featured image, a fast shutter speed did the trick. With yesterday&#8217;s peregrine image made at a much slower shutter speed, I made sure that the tripod legs were firmly planted in the soft hillside earth, made sure to press my face against the back of the camera, made sure to tighten both the horizontal and vertical panning knobs on the <a href=\"https:\/\/store.birdsasart.com\/shop\/item.aspx?itemid=274\">Mongoose M3.6<\/a>, and made sure to steady the lens with my left hand. Most of the time I support the lens barrel from below with my left hand while my forearm rests near the tripod platform; at other times I place my left hand atop the lens barrel. Which I do depends on the situation and is not anything that I could put into words. It is more of that gut feeling stuff. <\/p>\n<h3>The San Diego Site Guide<\/h3>\n<p>Whether you are visiting San Diego for photography for the first time or live in the area and have done the pelicans many dozens of times, you will learn a ton by studying the San Diego Site Guide. Why spend days stumbling around when you can know exactly where and when to be depending on the wind direction and sky conditions?
