Camera gear doesn’t guarantee great images, but it is a big help.  Although gear choices are generally in a state of flux this is what’s in the bag at the moment.

Body

Canon R5

Lenses 

Canon RF 15-35mm f/2.8 L

Canon RF 24-105mm f/4 L IS

Canon RF 70-200mm f/2.8 L IS

Canon RF 100-500mm f/4.5-7.1 L IS

Canon EF 500mm f/4 L IS

Teleconverters extend the focal length of telephoto lenses.  Teleconverters attach between the camera body and lens and as they absorb some light they reduce the maximum aperture by one stop with the 1.4x and two stops with the 2x.  So when adding the 1.4x TC to the 500mm f/4 lens it effectively turns the lens into a 700mm f/5.6 lens while by adding the 2x it becomes a 1000mm f/8 lens.  Extenders also affect the image quality of the lens however in my experience that effect is negligible with the 1.4x and not too bad with the 2x either.  The addition of the TC’s also slows the auto focus speed of the lens which does create some difficulties when shooting birds in flight. I presently use the EF 1.4x TC on the EF 500 f/4 and the RF 1.4x TC on the RF 100-500 zoom.

Flashes Canon 580EXII and Quantum off camera flashes.  I also use the Better Beamer flash attachment to extend flash range when using flash with long telephoto lenses.

Filters, especially Circular Polarizing and Neutral Density Graduated Filters are essential tools of the trade for landscape photography. Although filter effects (except the polarizing filter) can be largely duplicated in PhotoShop, I believe better results are obtained with less of an investment in time by using filters to help get the perfect landscape photograph.  I use a Lee 4×6″ filter holder and either Lee or Singh-Ray 4×6 ND grad filters. I have included links to the suppliers as I highly recommend both to you. Once you start using ND grad filters you will never leave home without them.  I also recommend Singh-Ray polarizing filters.

Software is essential to producing good results. I subscribe to Adobe Creative Studio with the bulk of image editing accomplished with Adobe Camera Raw (ACR) and Photoshop (PS). I also use two extremely helpful PS plug-ins, Raya Pro and Topaz Labs.
