Most macro lenses are generally in the 100mm range, but sometimes, macro photographers prefer longer focal lengths, as they can give better telephoto compression and longer working distances when trying not to disturb a subject. If you are interested in such a lens at an affordable price, check out this great video review of the IRIX 150mm f/2.8 Macro 1:1 lens.
Coming to you from Micael Widell, this helpful video review takes a look at the IRIX 150mm f/2.8 Macro 1:1 lens. The 150mm f/2.8 Macro is an affordable manual focus lens that features 1:1 minimum magnification, which equates to a 1.1-foot minimum focusing distance, 12 elements in 9 groups, Neutrino coating to suppress flares and ghosting for better contrast and color accuracy, weather-sealing for dust and moisture resistance, a rounded 11-blade diaphragm for smooth bokeh, an included tripod quality with an Arca-type foot, and a positive focus lock mechanism for maintaining the desired focus position while working. Altogether, it looks like a very interesting lens that could be a great choice for macro and portrait photographers, particularly if you do not rely on autofocus heavily for your work, as is often the case for macro photographers. Check out the video above for Widell's full thoughts.
