![]() With each ring and mount specially sealed to prevent water and dust from entering, this lens is ready for use in tough conditions. The lineup features the same dust and splash resistant structure* as the SIGMA 150-600mm F5-6.3 DG OS HSM|Sports. The end result is a combination of performance and compact design at the highest level. Featuring all functions essential to cinematography, these lenses keep weight and size to a minimum, while their specification is optimized for enhanced durability. Leveraging the high-precision, high-efficiency mass production technologies developed for its still camera lenses, SIGMA has made extremely lightweight and compact cine lenses a reality. These lenses are therefore ready for higher-resolution shooting and are ideal for chroma keying as well. The lineup features the same optical system that delivers 50-megapixel or higher resolution in still photography. Standardized color balance makes color correction a snap. The benefit of these efforts can now be enjoyed in cine lenses as well.Ĭolor balance standardized across the lineupĪll of the lenses in the lineup are designed to comply with SIGMA’s CCI standard. To fulfill the high demands for image quality in still photography, SIGMA has solved a wide range of issues. Sharpness combined with outstanding bokeh effect Ghosting has also been checked at every prototype stage, with its causes identified, assessed, and eliminated. Thanks to the ultra-high resolution sensors, high- performance shooting is assured.Ĭomputer-based ray tracing has been used from the design stage onward to minimize flare and ghosting and enhance contrast in backlit conditions. Each and every lens is checked before shipping. Even previously undetectable high-frequency details are now within the scope of their quality control inspections. SIGMA has developed their own A1 proprietary Modulation Transfer Function (MTF) measuring system using 46-megapixel Foveon direct image sensors. SIGMA lenses are born of outstanding design concepts and excellent manufacturing technology, but they are not complete until they undergo their uncompromising lens performance evaluation. There are three requirements for outstanding lenses: fine design, precise manufacturing and inspection that ensures compliance with all specifications. These options enable cinematographers to realize a wide range of expressive goals. T1.5 or T2 is available in prime lenses, while T2 is available throughout the zoom range in zoom lenses. The High Speed Zoom Line is compatible with Super35, the image size standard used by typical digital cinema cameras, while the FF High Speed Prime Line and FF Zoom Line are compatible with a full-frame image circle. Produce an entire work with SIGMA lenses alone.Ĭompatibility has been confirmed with each brand of cinema cameras. When the tracking locks on Birds In Flight it is a joy to use.The lineup covers everything from wide angle to telephoto. Takes time to find which AF Tracking focusing 'zones' work best for various subjects and movement.Ĭonclusion: I thoroughly enjoy the extra 'reach' I get and fun to use with great AF Tracking as long as you can keep ISOs to a minimum. AF Tracking slower or missed images in poor light conditions or lack of contrasting light. Lots of 'noise' in poor light conditions, due to higher ISOs. Low noise in good light conditions due to lower ISO.ĬONS: Loud mechanical shutter. Greater reach with APS-C sensor crop of 1.6X. Very fast AF Tracking for birds in flight or sports action in good light. Lighter body with good grip for small to medium sized 'male' hands. Great quality images in good light conditions. The two lenses I used are the RF 100-500 and the RF 14-35mm.F4. I have taken images in various light conditions and using two RF lenses to cover topics like birds in flight, landscapes, sunsets, waves, wakeboarding, boats etc. I have spent two weeks taking nearly 2000 images with the new Canon R7.
