Cell phone cameras have made vast improvements in the last few years and you could argue that they are now competing with or surpassing some digital still cameras. Some claim the resolving power of these very small, but carefully engineered, molded, (usually) plastic lenses compare equally to or better than the best 35mm lenses. To be sure, cell phone cameras have a number of limitations due to their small sized sensors, but their portability can’t be beat and the pictures are quite good.  A complete review of this camera-phone (and others) can be read at www.dpreview.com.

Laurie Tisch founded the Laurie M. Tisch Illumination Fund in 2007, building upon her decades of experience serving on boards, building organizations, and developing partnerships. She is Co-Chair of the campaign committee for the Children’s Museum of Manhattan, a trustee and past Chair of the Whitney Museum of American Art and a Vice Chair at Lincoln Center for the Performing Arts as well as a Trustee of the Aspen Institute and a co-owner and member of the Board of Directors of the New York Football Giants.

Announced a $10 million initiative to support organizations that utilize the arts as a tool for healing and for building understanding of critical societal issues such as mental health stigma and trauma.

The Illumination Fund generates initiatives through targeted research and long-term partnerships, and does not accept unsolicited requests for funding.

Launched a partnership with New York City Health + Hospitals to expand the hospital system’s Arts in Medicine programs serving health care staff, patients, and communities in sites across the City.

The Laurie M. Tisch Illumination Fund aims to increase access and opportunity for all New Yorkers and foster healthy and vibrant communities. The fund uses an equity lens to develop initiatives and to issue grants, driven by the principle that everyone should have access to positive and enriching opportunities that define a full range of human experience and that circumstances of birth should not limit choices or short circuit success for anyone.

There are a surprising number of different camera formats (sensor sizes) to choose from now compared to a few years ago. In order to compare various camera formats we typically use the standard 35mm film size (36 x 24mm) as our basis of comparison since that has been the standard for so many years. We know we will get a certain field-of-view (FOV) and depth-of-field (DOF) with various focal length lenses for this format so we use a lens based on these parameters to get the picture we want. But if you consider using a lens with the same focal length on a camera with a smaller sensor, the FOV and DOF parameters will be quite different. So, we make the comparison with an equivalence, like a sensor crop factor of 1.5 (or 1.6 depending on the camera) for an APS-C sensor. For example, we can say that a 100mm lens on an APS-C camera will give an equivalent FOV as a 150mm (or 160mm) lens on a full-frame camera.  Similarly, if we want the same FOV as a 100mm lens on a full-frame camera, we know that the equivalent lens on an APS-C camera would have to be about 67mm.

Note that some the equivalences shown in the table for the smallest sensors are theoretical since their design does not provide an equivalent focal length. The iPhone 5 camera, for example, has a fixed lens with a focal length of only 4.1mm so it is obvious that it will not provide the same FOV as a 50mm on a full-frame camera. If you know the focal length of the lens and the sensor crop factor, you can compute the equivalent focal length. So, for the iPhone it is 4.1mm x 7.1 = 29.1mm.

The Illumination Fund has a staff of three seasoned professionals with more than 50 years of collective experience in philanthropy and related fields. Executive Director Rick Luftglass’s career has included private foundations, nonprofit organizations and corporate philanthropy, has consulted for government agencies, and has expertise that spans health care, the arts, education, community and economic development, housing, urban history, and immigrant communities.

The Illumination Fund’s office is an extension of the foundation’s mission and values, with contemporary art, exhibits by our grantees, and furniture that supports community artisans and social enterprises. The space was designed by BKSK Architects to “illuminate” community and social justice issues and to spark creativity.

Began 10 years of support for public service initiatives in New York City with the Mayor’s NYC Service programs and with Be the Change and its ServiceNation movement- building campaigns.

Launched a 5-year, $15 million commitment to advance novel strategies to increase access, availability, affordability, and knowledge of healthy foods and promote healthy choices, specifically targeting programs in high-need neighborhoods and creating hubs of activities and community engagement.

The Illumination Fund undertook three strategies to respond to the pandemic: coordinating with other funders to identify needs and gaps and to amplify collective efforts; bolstering the work of long-time grantees to help them pivot, and addressing the disproportionate impact on low-income communities.

Keep in mind that loss of image quality due to diffraction is based on the exit pupil of the lens not the lens f-stop and this is why very small sensor cameras (with very small lenses) experience diffraction at much lower f-stops than large sensor cameras.  Diffraction becomes an issue around f/2.0 to f/3.0 in camera-phones vs. f/16 to f/22 for full-frame cameras.

If you are considering buying another camera with a different sensor size than the one you have, this concept of equivalence is useful since you will know what focal length lenses will give you a similar FOV and DOF as the camera you currently have. For example, the FOV and DOF of a 50mm f/2.8 lens full-frame camera will be the equivalent FOV and DOF as a 25 mm f/1.4 lens on a micro 4/3 camera. The table above should help illustrate this equivalence for a number of popular sensor sizes. The difference in DOF is often an important consideration for photographers interested in creating dreamy out of focus backgrounds. There are lenses made for micro 4/3 format cameras with apertures as large as f/0.95 in order to produce out of focus areas comparable to those obtained with full-frame cameras.

The Laurie M. Tisch Illumination Fund explores funding ideas and generates initiatives through targeted research, long-term partnerships, and networking with thought leaders. The foundation accepts proposals by invitation only and does not accept unsolicited requests for funding.

Began a multi-year partnership with the NYC Department of Health and Mental Hygiene and the Mayor’s Office of Food Policy to create a new network of street vendors to increase access to fresh fruits and vegetables in high-poverty neighborhoods with limited availability of healthy foods.

Finally, if you are thinking of lightening your load with a smaller camera, there are now many choices to consider. Remember, in terms of image quality, sensor size is the most important feature to consider and that higher megapixel count does not always equate to higher image quality. I hope you find the concept of equivalency helpful in comparing cameras with different sensor sizes and in selecting a camera to fit your needs. The choice is yours – bigger sensor, bigger weight and size. Smaller sensor – smaller weight and size.
