I was looking at some iPhone photos from a month ago and came across this photo. My dog and I were out walking at one of the local lakes and I took this picture with my iPhone. Hundreds of yards off in the distance (upper left) I saw some people on the lake, so I got out my “toy” camera and lens. (See the 2nd and 3rd links below).<\/p>\n

With my Canon SL3 DSLR and a 55-250mm lens I have a much better image, which is exactly what you would expect. You are looking at the whole image, uncropped, and resized for the web. Four people are clearly visible. The lens was set at 250mm. The SL3 has a cropped sensor so the field of view is the same as a 400mm lens on a full frame digital camera. (See the field of view crop article linked below.)<\/p>\n

It is no surprise that a 250mm lens will provide a much better image than an iPhone.<\/p>\n

I zoomed in on the center of the DSLR image to 100%, actual pixels and this is the result. I am guessing this is two dads with their sons. I must say I was a bit surprised at the amount of detail in this image.<\/p>\n

Google Earth Pro<\/p><\/div>\n

The fishermen in the image are about even with a small bay on the west side of the lake, so I used Google Earth Pro to check the distance. My location near the parking circle is at the upper end of the yellow measurement line. The approximate location of the icy fishermen is at the lower end of the yellow line.\u00a0 They were about 450 yards away from my camera. I must say I was surprised a 250mm lens can provide so much detail at that distance.<\/p>\n
