The Panasonic Lumix G Macro 30mm f/2.8 ASPH is designed to be used with Micro Four Thirds (MFT) system cameras and provides an angle of view equivalent to a 60mm lens on a 35mm camera and life-size magnification at its closest focus distance. Overall, it is an outstanding updated macro lens ideal for all short telephoto applications. There does remain the possibility of picking up the previous model at a much lower price, should cost be the main factor for you, but with what this lens has to offer, it's well worth the asking price.ģ. The Tamron SP 90mm f/2.8 Di Macro 1:1 VC USD builds on the reputation of its predecessors and definitely coming up to the mark. This one takes performance to a new peak and is very comfortable to use. Plus, it works so well on the A7R II that it should be an essential buy for those using this particular system.Ģ. Tamron SP 90mm f/2.8 Di Macro 1:1 VC USD The Sony FE 90mm f/2.8 Macro G OSS is slick in use and produces excellent macro images. The price may be a little on the high side, but on the other hand, there is little choice for the Sony A7 range user, unless we look at less expensive manual focus lenses. It doesn't cost you anything extra when you press our Amazon buttons but by using our Amazon Affiliate links when ordering anything online, you are supporting the site - thank you.

Choose used and get affordable access to kit that doesn’t cost the earth. Every month, visual storytellers sell more than 20,000 cameras and lenses to MPB. * AF will not function with Pentax ist* series and K100D DSLR cameras that do not support HSM.MPB puts photo and video kit into more hands, more sustainably. * Sony A and Pentax mounts are not incorporated with OS function. To find which DC lens is equivalent to a full frame lens, divide the focal length of the full frame lens by the same crop factor. To find the 35 mm camera equivalent focal length, multiply the DC lens focal length by the “crop factor” (digital multiplier) of 1.5, 1.6 or 1.7, depending on the brand of DSLR camera on which the lens will be used. * Vignetting will occur if the lens is used with image sensor larger than APS-C size or 35mm SLR, and APS Film SLR cameras. The degree to which light is refracted by glass depends on the light's waveleng…Īll figures calculated by SIGMA SA mount. SIGMA’s original OS (Optical Stabilizer) function uses sensors inside the lens … The polygonal shape of a conventional iris dia phragm causes out-of-focus light… The Hyper Sonic Motor (HSM) is an original SIGMA development that uses ultrason… The brass mount combines high precision with rugged construction. High-precision, rugged brass bayonet mount.Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration. In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. ![]() ![]() To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). ![]() Yet residual chromatic aberration known as “secondary spectrum” may still remain. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. This fact causes different colors of light to focus at slightly different points. The degree to which light is refracted by glass depends on the light’s wavelength.
