currently it’s quite harder to quickly see a collapsed method/block in my opinion… *edit: just try yourself at the above comment of Ricardo Rocha: focus your eyes on the “Main(string[] …” part: in the first img (+/-), you can clearly see that there is somethi...
using 17 mm and 13 mm Ethos and 2 inch 2x Barlows and spacing them, he can achieve a wide range of magnifications with nearly zoom like coverage, achieving something over 500x in his 18 inch F/4.5 Obsession.
for example, creates images that are 4,288 by 2,848 pixels, which works out to 12,041,344, or a little over 12 megapixels. That camera is already a few years old; newer models can take even larger pictures.
With a 17-40mm lens, bring a 70-300mm instead. The 40-70mm range doesn't matter: take a step forward or back. If you bring a 50mm macro, don't also bring along a regular 50mm lens or a zoom that covers 50mm.Most modern zooms have great macro ability, so you probably won't ...
Once you know the image depth, which simply is how far you need to move your lens in and out to focus on the nearest and farthest parts of your image, you can read the optimum aperture right off a scale. These scales are similar to the familiar depth of field scales. ...
cameras are larger than compact cameras and they tend to have big zoom lenses that can capture far away subjects. Like with compact cameras, you can’t change the lens like on mirrorless or DSLR. They tend to offer a good balance between image quality, zoom, weight, usability, an...
I became interested in training my macro lens on other subjects, such as the forest floor (where I like to capture leaves, especially in autumn), snow (when viewed up close, snowflakes are fascinating!), and ice. You can choose to follow my example, or you can strike out on your own...
Canon has theR6, which is the most affordable full-frame mirrorless camera I would recommend for action photography. Their Canon 100-500 f/4.5-7.1 lens is also very light for a long zoom, so this lens with the R6 would make a very capable and lightweight wildlife system, albeit with a...
Nevertheless I am going to show you on the following pages, that things are not that bad, and that you can understand the basic relationships without an excursion into higher mathematics of Fourier-optics. After reading the paper you will be able to conclude about the character of a lens ...
Beam Mode • Beam Zoom Optics: A 6-element 10:1 zoom optics system, covering a range from 4° to 40°. • Beam Size Control: A mechanical iris provides continuous beam size control for rapid and smooth timed beam angle changes. Near zero degree beam angle is possible with nearly ...
