![]() ![]() Tamron SP AF 28-75mm F/2.8 XR Di LD Aspherical Sony We’ve performance data on some of the latest models but we’ve also included information from a few of the older Konica Minolta lenses that can be found used at competitive prices: Listed below are some of the lenses we’ve analyzed. We’ve tested the Alpha 99 with 22 different A-mount lens models (primes as well as zooms) with a range of focal lengths encompassing 16mm to 500mm, including Sony made lenses and those from third parties. The aim of this concise guide is to assist the reader in choosing the most appropriate lens for the camera based on optical performance, while being mindful of the price. As well as the option to capture 14-bit RAW files, the camera also adopts what the firm describes as ‘newly developed multi-segment OLPF’ designed to enhance the sensor’s resolving power.Īs promising as all this sounds, the sensor is only a part of the imaging chain and the image quality will inevitably vary across different lens models. As successor to the A900 DSLR, the SLT-A99 stands-out as the first full- frame model from the firm to move to an electronic viewfinder and the first to supplement the viewfinder AF system with a second 102-point PDAF-assist sensor array overlaying the 24.3- MPix CMOS sensor. In fact, this system allows for full-time continuous phase-detection AF ( PDAF) during live view and video capture. ![]() Fixed “pellicle’ mirrors aren’t new of course, the partially silvered mirror allows for conventional viewfinder based phase-detection AF and metering systems to be retained. As well as adopting an electronic viewfinder, the novel system utilizes a semi-transparent mirror (or “Translucent” mirror, as Sony calls it), which remains in the lens’ light path. With the introduction of SLT models featuring the novel ‘translucent’ mirror technology, Sony were the first to break with the traditional reflex mirror and optical pentaprism found in rival SLR systems.
