Consider how to use: Only System vs 2nd Camera 2. Consider style: Rangerfinder vs Scaled-down DSLR 3. Sensor Size determines format and (in some cases) manufacturer • Sensor size & number of megapixels determine maximum print size 4. Consider the lens system • Not many 3rd party lenses, but adapters increase options • Are your favorite focal lengths available? (Account for crop factors) 5. Built-in Electronic Viewfinder (EVF) 6. Set your priorities for remaining features & make a list • Don’t assume a feature is included – lots of variability among models/manufacturers Rent before you buy •Try out one or more cameras with a lens before you buy •Rent for 4 – 7 days to really get a feel for what it can and cannot do •http://www.borrowlenses.com/ •http://www.lensrentals.com/ (have a keep & buy option) •https://www.lensprotogo.com/ •Shoot dual JPG/RAW as your software might not recognize newer RAW formats How to shop for a mirrorless camera Online Buying Sites Remember to scroll down http://www.adorama.com/catalog.tpl?op=itemlist&cat1=Cameras&cat2=Mirrorless%20Cameras Can’t filter by features http://www.bhphotovideo.com/c/buy/Mirrorless-System-Cameras/ci/16158/N/4288586281 • Can filter by features (built-in EVF, swivel/tilt LCD, built-in flash, GPS, Wi-Fi, Mic Input, etc) 1.

    All About Raspberry Pi HQ Camera Lenses Created by Dylan Herrada Last updated on 2020-10-19 07:56:39 PM EDT Overview In this guide, I'll explain the 3 main lens options for a Raspberry Pi HQ Camera. I do have a few years of experience as a video engineer and I also have a decent amount of experience using cameras with relatively small sensors (mainly mirrorless cinema cameras like the BMPCC) so I am very aware of a lot of the advantages and challenges associated. That being said, I am by no means an expert, so apologies in advance if I get anything wrong.

According to Wikipedia (https://adafru.it/MF0): In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference.

  • A Practical Guide to Panoramic Multispectral Imaging
    A PRACTICAL GUIDE TO PANORAMIC MULTISPECTRAL IMAGING By Antonino Cosentino 66 PANORAMIC MULTISPECTRAL IMAGING Panoramic Multispectral Imaging is a fast and mobile methodology to perform high resolution imaging (up to about 25 pixel/mm) with budget equipment and it is targeted to institutions or private professionals that cannot invest in costly dedicated equipment and/or need a mobile and lightweight setup. This method is based on panoramic photography that uses a panoramic head to precisely rotate a camera and shoot a sequence of images around the entrance pupil of the lens, eliminating parallax error. The proposed system is made of consumer level panoramic photography tools and can accommodate any imaging device, such as a modified digital camera, an InGaAs camera for infrared reflectography and a thermal camera for examination of historical architecture. Introduction as thermal cameras for diagnostics of historical architecture.

  • Hasselblad V to Fuji GFX Speedbosster Press
    Metabones® Introduces Hasselblad V to Fuji G mount (GFX) Speed Booster® Press Release n Los Angeles, CA, USA, Aug 16, 2019: Caldwell Photographic Inc. and Metabones® are pleased to announce a new Speed Booster® Ultra 0.71x, exclusively designed for the exciting new Fuji GFX medium format camera. The initial version is specifically optimized for use with the famous Hasselblad V series lenses. This new Speed Booster uses an advanced 6-element design to achieve excellent optical performance at apertures up to f/1.4 when paired with the Hasselblad 110mm f/2 lens. Although the Fuji GFX uses an extremely large sensor, it is nevertheless significantly smaller than the 6x6 cm film format. The new Speed Booster Ultra 0.71x is an ideal match for 6x6 Hasselblad V lenses since they can now be fully utilized as they were originally designed when mounted to the Fuji GFX. Unlike 35mm format lenses used on the Fuji GFX via glassless adapters, Hasselblad V lenses adapted to the GFX via the Speed Booster Ultra are completely free of disturbing vignetting and other corner issues. In addition to increasing the field of view and lens speed, the new Speed Booster Ultra achieves superb performance by being carefully matched to the unique optical characteristics of the Hasselblad V lenses. All of the Hasselblad V lenses were analyzed for exit pupil size and location, and this was fully taken into account in the new Speed Booster Ultra for the Fuji GFX. This approach dictated the use of extremely large lens elements throughout in order to avoid vignetting and maintain high quality imagery into the corners, but the results speak for themselves.

  • Innovation and Recurring Shifts in Industrial Leadership: Three Phases of Change and Persistence in the Camera Industry*
    Innovation and Recurring Shifts in Industrial Leadership: Three Phases of Change and Persistence in the Camera Industry* Hyo Kang† Jaeyong Song‡ Forthcoming in Research Policy 46(2), 2017 Abstract This study examines factors underlying three phases of change/persistence in industrial leadership in the segment of interchangeable-lens cameras over the past century. During this period there were two major phases of leadership change, both associated with the emergence of innovations involving major discontinuities in the industry’s core technologies. First, Japan won market leadership from Germany in the mid-1960s after commercializing the single-lens reflex (SLR) camera that replaced the previously dominant German rangefinder camera. Second, in the late-2000s, Japanese latecomer firms and a Korean firm developed Mirrorless cameras, which allowed them to capture the majority of market shares from the incumbent Japanese leaders. We also examine the long period (about 60 years) between these two phases of change, during which leading Japanese firms were able to sustain their market leadership despite the digital revolution from the 1980s to 1990s. This paper explores the factors influencing these contrasting experiences of change and persistence in industry leadership. The analysis integrates several aspects of sectoral innovation systems – i.e., windows of opportunity associated with technology, demand, and institution – as well as the strategies of incumbents and latecomer firms. The conclusions highlight the complex and diverse combinations and importance of the factors that help explain the patterns of leadership shift. Keywords: catch-up cycle; industrial leadership; innovation; interchangeable-lens camera JEL: N70, L63, O33 * This research has been supported by the Center for Global Business and Research, Seoul National University.

  • Infrared with Mirrorless Cameras
    Digital Infrared Photography And Mirrorless Cameras by Steve Zimic A Primer on Infrared Light Much of photography these days is about making images that portray subjects differently than the way we see them with our eyes. A heavily processed High Dynamic Range image is a prime example. Another is astrophotography, which allows us to see images of distant galaxies in glorious colors that the human eye could never see. Forensic photographers photograph crime scenes and artwork using infrared and ultraviolet light to reveal hidden details. All of this gives new meaning to the expression "seeing things in a different light". Infrared photography is perhaps the easiest and most dramatic of those mentioned above. The two images below show how a normal scene is transformed into something quite unique when photographed primarily with Infrared (IR) light. Foliage becomes much brighter while the water, sky and structure become considerably darker. So exactly what's going on that creates this unusual effect? Let's start off with the prefix 'infra' which means 'below'. The color red is at the very bottom edge of the visible spectrum of light, therefore infrared light is below or not visible, to us humans at least. Looking at the chart below, you can see that the infrared range of light is huge compared to the visible spectrum, but ordinary digital cameras can only see a small portion of that range, appropriately named 'near infrared' implying it's near the visible red light. The goal of infrared photography is to capture an image that's comprised primarily of that near infrared light.

  • Lens Mount and Flange Focal Distance
    This is a page of data on the lens flange distance and image coverage of various stills and movie lens systems. It aims to provide information on the viability of adapting lenses from one system to another. Video/Movie format-lens coverage: [caveat: While you might suppose lenses made for a particular camera or gate/sensor size might be optimised for that system (ie so the circle of cover fits the gate, maximising the effective aperture and sharpness, and minimising light spill and lack of contrast... however it seems to be seldom the case, as lots of other factors contribute to lens design (to the point when sometimes a lens for one system is simply sold as suitable for another (eg large format lenses with M42 mounts for SLR's! and SLR lenses for half frame). Specialist lenses (most movie and specifically professional movie lenses) however do seem to adhere to good design practice, but what is optimal at any point in time has varied with film stocks and aspect ratios! ] 1932: 8mm picture area is 4.8×3.5mm (approx 4.5x3.3mm useable), aspect ratio close to 1.33 and image circle of ø5.94mm. 1965: super8 picture area is 5.79×4.01mm, aspect ratio close to 1.44 and image circle of ø7.043mm. 2011: Ultra Pan8 picture area is 10.52×3.75mm, aspect ratio 2.8 and image circle of ø11.2mm (minimum). 1923: standard 16mm picture area is 10.26×7.49mm, aspect ratio close to 1.37 and image circle of ø12.7mm.
