The beauty of the natural bokeh that increases gradually as the distance from the focal plane
increases is best seen with portrait photography.
One of the new scopes is the CTA2104 2-Series 1-4X 24mm FFP (first focal plane
 discovered that the output current of their new multijunction solar cell decreased slightly on the designed focal plane
of the lens.
On a scope with a magnification range of 1-8X, I think the front focal plane
reticle is the way to go.
The observation error is analyzed in Section 2, and the observation based on focal plane
imaging was modeled.
The fluorescent signals are conceived to come from the plane at the chosen depth which is named focal plane
More manufacturers are adding first focal plane
reticles these days, and Burris' Ballistic Plex E1 FFP is a great example.
Available in the second focal plane
(SEP) with multiple reticle options, both scopes feature a FREE SBT (SIG Ballistic Turret) calibrated to a shooter's unique ballistic and environmental conditions.
(1) Ground calibration method , which is also called program control method: according to the actual measured disturbances, such as temperature, atmosphere pressure, and distance to the ground, which would change the location of the focal plane
, this method uses a preinstalled program which is calibrated in advance to adjust the actual position of the focal plane
The top-quality focusing mechanism moves smoothly without backlash, optimally supporting the photographer's creative interplay with the focal plane
of high-speed fixed focal lengths.
As he recounts, "After much brainstorming with Zemax, I realized that excellent field corrections could be obtained by including just two simple lenses ahead of the focal plane
The new flagship fullA[degrees]frame mirrorless camera, the [eth]7R II, delivers an innovative imaging experience with the world's first backA[degrees]illuminated 35mm fullA[degrees]frame senA[degrees] sor Exmor R CMOS sensor, which realises highA[degrees]resoluA[degrees] tion (approximately 42.4 effective megapixels), highA[degrees]sensitivity (expandable up to ISO 102400) and highA[degrees]speed AF response up to 40 per cent faster than the original [eth]7R, thanks to 399 focal plane
phase detection AF points.
