We present a catalog of 25 definite and 11 probable strong galaxy-galaxy gravitational lens systems with redshifts 0.4 \lesssim z \lesssim 0.7, discovered spectroscopically by the presence of higher redshift emission-lines within the Baryon Oscillati...
Spectroscopic galaxy-galaxy lens searches are presently the most prolific method of identifying strong lens systems in large data sets. We study the probabilities associated with these lens searches, namely the probability of identifying a candidat...
We present a weak lensing cluster search using Hyper Suprime-Cam Subaru Strategic Program (HSC survey) first-year data. We pay special attention to the dilution effect of cluster member and foreground galaxies on weak lensing signals from clusters of...
We describe several extensions to TIM, a raytracing program for ray-optics research. These include relativistic raytracing; simulation of the external appearance of Eaton lenses, Luneburg lenses and generalized focusing gradient-index (GGRIN) lenses,...
This tool lets you check the compatibility of your Pentax digital camera with any Pentax lens or any current third-party lens. Type a partial name to see suggestions.

May 24, 2017 · The "surgery" itself went without surprises - disassembled the camera, removed the sensor module, removed the lens mount, installed one from pixaero, installed the lens and put it all …
Jun 27, 2020 · As jb57 states, the lens of the C23 is in fact a 39mm lens and; Yuneec does supply a 40.5 mm adapter ring but since you mentioned you don't know much about photography stuff I would …
Dec 1, 2018 · The lens can be changed quiet easily. On my Typhoon H (CGO3+) I swapped the original lens to one made by Peau Production. The main reason for doing so was not to gain more focal …
It has been recently proved that a slab of negative refractive index material acts as a perfect lens in that it makes accessible the sub-wavelength image information contained in the evanescent modes of a source. Here we elaborate on perfect lens s...

Applying the directionality of a Luneburg lens, a sound reception system for ships is designed. A two-dimensional acoustic Luneburg lens which is made of 253 acrylic pipes of different radii which control the refractive index is used. It has a large...
A time lens allows one to stretch or compress optical waveforms in time, similar to the conventional lens in space. However, a single-time-lens imaging system always imparts a residual temporal chirp on the image, which may be detrimental for quantum...
Using Givental's non-linear Maslov index we define a sequence of spectral selectors on the universal cover of the identity component of the contactomorphism group of any lens space. As applications, we prove for lens spaces with equal weights that th...

It’s been over 2 years since my last lens purchase. I finally crossed the milestone of owning a lens that is worth more than my camera body! I’m very pleased with the fuji 18mm F1.4. It is incr...

May 9, 2022 · The Sigma II Macro 28 80 mm f/3.5 5.6 is a lightweight, budget-friendly zoom lens produced in the late 1990s and early 2000s for various mounts, inclu. This is a Sigma Zoom lens.
To take a photograph, the lens makes a small picture of the object inside the camera, which it does by focusing light. A lens in a camera works like a lens in glasses (spectacles) or a magnifying glass.
