e-mount also has two other xlnt 135/1.8 af options at much lower prices, that rf-mount does not have because it's a closed mount. Like 6Nov 10, 2022*permalink photogopinion TRU: I’m sure the greater part of the rest of the world is very happy for you and all Canon users ...

If R is greater than 1, the moving lenses will be positive, and if R is less than 1, the moving lenses will be negative. In order that the rear air space will be positive, where d′b = (fb + fc + S), we must select reasonable starting values for X. Approximate suitable values...
The lens has been considered to be an immune privileged site not susceptible to the immune processes normally associated with tissue injury and wound repair. However, as greater insight into the immune surveillance process is gained, we have reevaluated the concept of immune privilege. Our studies ...
A 0.70x maximum magnification from a non-prime-macro lens is eye-opening and significantly more impressive than the 24-105L II's 0.24x spec. However, it should be kept in mind that a 12mm extension tube can push the 24-105 to 0.60x maximum magnification. Disclaimer: I have not made ...
Magnification from telephoto focal length lenses is not significantly increased with the use of extension tubes, hollow tubes (with electronic connections) that shift a lens farther from the camera, but all Canon super telephoto lenses are compatible with these. This shift allows the lens to focus...
that they have virtually the same pixel pitch as the 100MP sensor has. The lenses onthose cameras are already capable of sufficient resolution for these cameras… and a 100MP miniMF sensor places no greater stress on the lenses.To be honest, this actually suggests that their Fujifilm lenses ...
To make our simulation more efficient and to obtain a better ray resolution at the analysis surface, i.e., a greater number of rays at each pixel of the detector surface, we defined a direction of interest for the scattered beams. In our case, scattered rays were only generated in a ...
lens uses a right-angle prism to turn the original optical path by 90 degrees. The thickness of the lens is determined by the size in the Y-direction of each lens or the prism, so that the zoom system has enough space for the embedding of a high-magnification zoom lens in a ...
The first question to ask yourself is, “What do I need that my current lens doesn’t give me?” In terms of functionality, your answer is most likely going to fall into one of two categories: speed (aperture) or versatility (focal length/zoom). Let’s look at the first factor and ...
