What is a Zoom Lens? And why and when to choose a Zoom Lens?

Sigma offers a great variety of zoom lenses. (Lenses are not shown to scale in this display.)

A zoom lens is a type of camera lens that is offers the photographer a useful range of different focal lengths in a single lens. This is in comparison to a prime lens, which only offers a single focal length. A zoom lens allows for quick and easy re-framing of a scene while staying in the same physical position. Sigma offers a line of over 20 zoom lenses for DSLR photographers, ranging from wide angle zoom lenses, supertelephoto zoom lenses, and high-zoom ratio all-in-one lenses for both full-frame (DG) and APS-C (DC) digital cameras.



All-in-One Wedding Solution: Sigma 24-105mm F4

This month I was invited by Sigma to test out their brand new Sigma 24-105mm F4 lens and to shoot a series of bridal images to demonstrate the versatility of the lens. I decided to put together a fashion-influenced bridal shoot in a stunning location and with the help of my incredible talented creative team. Once I had put together striking visual elements, I would then test all features of the lens that would be important to me as a working photographer.

For several years I photographed weddings, and all the challenges that come with them. I realized very quickly that the last thing I wanted to worry about was my gear. I had to focus on the posing, the lighting, keeping everyone happy, my extremely long shot-list, and much more. I needed to know my gear was reliable and would help me get those must-have moments. When I started I didn’t have a second shooter or assistant; I was the one-woman band expected to make every shot count.



Photograph Anyone’s Good Side: Part 2

© 2013 Lindsay Adler

When your job is to flatter your portrait subjects, you need as many tools in your photographic toolbox as possible so you are prepared for any features, and any ‘flaws’.

I think it is important to mention that I am not judging people’s appearance. As a fashion photographer, I often get to photograph what society considers “ideal” forms of beauty. What I notice time and time again, however, is that certain models’ “flaws” are what make them unique and memorable. In fact, there are several supermodels with so-called flaws like gapped-teeth, unusual noses, and more.

What matters is not what society says is ‘perfect’ but instead how your subjects perceives themselves. You want them to feel confident, attractive and proud of the images you provide them. You want to help them reduce anything they are self-conscious about and help their expression glow in their images.
