And it has introduced various lenses that would fit into the cameras it’s been selling.Ĭurrently, there are two showrooms of Canon camera and lenses in Nepal. Primax International has a complete lineup of Canon’s DSLRs and mirrorless cameras in Nepal. Primax International is the designated official to handle the sales of genuine Canon Products in Nepal. There is an authorized distributor for Canon products as well. Sony Vario-Tessar T* FE 24-70mm f/4 ZA OSS Lens It really is an outstanding macro lens.Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS Lens Compared with Sigma’s older, more DSLR-biased 105mm macro, the DG DN edition costs about 50 per cent more to buy in the USA and is nearly twice the price in the UK, but it’s still very good value for money. It has excellent build quality and a raft of high-end handling attributes, including a physical aperture ring with a declick switch, customisable autofocus hold button, autofocus range limiter, and incredibly high-precision manual focusing, ideal for macro shooting. Reasonably compact and lightweight, Sigma’s 105mm macro lens for Sony E and Leica L mount cameras is easy to live with. There's modest pincushion distortion, but it's not so severe as to be distracting, and it's easily correctable. Lateral chromatic aberration is consistently minimal throughout the aperture range - you're unlikely to spot any fringing in real world shooting. All in all, this macro lens is a top performer. The latter often occurs in ‘fast’ lenses when shooting at or near the widest available aperture, typically presenting as green or magenta fringes around high-contrast edges within scenes that are slightly in front of or behind the point of focus. Colour fringing is very well controlled, not only for lateral chromatic aberrations into the extreme corners of the image frame, but also for longitudinal or ‘axial’ chromatic aberrations. The electronically coupled ‘fly-by-wire’ focus ring enables a supremely fine level of manual focusing adjustment, which is great for straightforward macro shooting as well as for focus stacking, where you take a series of shots with incremental focus shift, for merging into a single image at the editing stage.įor actual image quality, the lens lives up to Sigma’s claims, with superb sharpness across the whole image frame, throughout the aperture range, along with excellent contrast. Due to the incredibly tight depth of field in macro photography and the need for ultimate precision, manual focusing is often preferred to autofocus. Autofocus is fast and utterly reliable, while manual focusing is an absolute joy. The features and build quality are work well together to deliver fabulous overall performance. More of a rarity on DG DN lenses, there’s also an autofocus range limiter switch, which can optionally lock out the long or short end of the range either side of 0.5m. This enables precise aperture adjustments for stills in one-third f/stop increments, or stepless aperture control when shooting video. There’s also the usual physical aperture ring, towards the rear end of the lens, which comes complete with a ‘Click on/off’ switch. As such, there’s an onboard AF/MF switch plus a customisable function button which is nominally set to Autofocus-Lock by default. Handling is significantly improved, compared with the older DSLR-biased lens, with all of the Sigma DG DN trappings that we’ve come to expect. Typical of newer designs in the line-up, it features a comprehensive set of weather-seals, as well as a fluorine coating on the front element to repel moisture and grease. As of yet, these teleconverters are unavailable in Sony E-mount.Īs with other Sigma Art lenses, the build quality of this macro prime is very good indeed. One bonus of the L-mount edition is that it’s also compatible with Sigma’s latest 1.4x and 2.0x teleconverters, which can boost the maximum macro magnification to 1.4x or even 2.0x respectively. That’s not really a problem when shooting with later Sony mirrorless bodies, that have IBIS (In Body Image Stabilization), as also featured in Panasonic’s L-mount cameras. One thing that’s missing, compared with the older DSLR-biased lens, is that the DG DN has no optical image stabilizer. It’s equally adept at portraiture, where the f/2.8 aperture produces a fairly tight depth of field. With a fast and near-silent stepping motor autofocus system, it’s good for shooting wildlife or sporting action, even under dull lighting conditions, where the f/2.8 aperture enables fairly fast shutter speeds without having to bump up your camera’s sensitivity settings too much. Another similarity with most modern macro lenses is that the Sigma works well as a fast, short telephoto prime for general shooting.
