The marked focal length on the lens is the actual focal length of that lens, that will never change. But, to help explain or understandwhat lens this would be on a FF 35mm, the crop factor was marketed since most of us understand FF 35mm lens coverage. What you do is multiply the ...
b) We all know that effective focal length changes with all moving mirror systems but it is not easy to calculate the exact number, to me more important than the change in focal length is the change in effective aperture with these systems, perhaps you should include that number as well in...

The field in the anode bore acts as a diverging lens of a focal length fA that moves the virtual vertex to z = − w′S = fA wS(wS − fA)− 1. The lens also enlarges β → β′ and in the paraxial approximation (i.e., when we can put tan β ≅ sin β ≅ β),...
Note that the longer your focal length, the shallower the depth of field. So if you use a telephoto lensandyou shoot at an aperture of f/2.8, the fence will be blurrier than if you photograph with a wide-angle lens at f/2.8. ...
To end on a simpler idea: Safe Pareto improvements may be Schelling points (a.k.a. focal points) in some settings. For instance, you might imagine a setting in which the above justifications don’t quite apply. Then SPIs might stand out by virtue of standing out in slight alterations of...
Tell me a focal length, or should I just make it 10mm, 9mm, and 10mm respectively? That makes sense, thanks. I've actually never felt my Delos/Delite/XW varying all that much in effective eye relief between focal lengths, but given your results I'm probably wrong about that!
The second-level contrast analysis examining the differential response between medial group and lateral group stimulation showed that a number of focal anatomical sites exhibited significant difference (Fig.3d) including in Thalamus, preCG, postCG, SFG, MFG, IFG, Precuneus, AG, STG, ITG, and infe...
No significant differences in postoperative complications (8 LDJP vs 9 supine, P = 0.675) or length of hospital stay (25 LDJP vs 26 supine, ≥ 7 days) (P = 1.000). Conclusion Laparoscopic partial hepatectomy in LDJP for hepatic VI/VII tumor safe and feasible. Reduces ...
The following parameters for the therapeutic US transducer were used: 1) frequency: 0.85 MHz (or 1.04 MHz); 2) focal length: 135.0 mm (or 151.0 mm); 3) diameter: 20 cm; 4) the scanning method: point-by-point method; 5) depth: the distance on the US channel from the center of ...
