The Nikon 300mm ƒ/4E PF ED VR AF-S hit store racks in February 2015: touted as the world’s lightest 300mm full-outline lens, it’s anything but difficult to consider why, to be it weighs just 755 grams (a little more than 26 oz).
The lens offers an assortment of specialized advancements, however the principle fascination is its Phase Fresnel lens component, which wipes out the need to utilize a convoluted course of action of lens components to revise chromatic variation and decrease flare. Less components implies less weight and less obliged space to house them.
Plan and Features:
The test results for the Nikon 300mm ƒ/4 PF as to chromatic variation were exceptionally great – the lens is exceedingly safe, on both of our Nikon D7000 and D800e test bodies, over all openings. There is some minor corner shading when the lens is utilized on the D7000 at ƒ/4. It’s more noteworthy when the lens is utilized on the full-outline D800e: at ƒ/4, the amazing corners are very nearly 1/2 of a stop darker than the inside. This is alleviated as the lens is ceased down: At whatever other gap, corner shading is immaterial.
The 300mm ƒ/4 PF utilizes an AF-S assignment and is moderately quick to self-adjust, racking through its nearby center to limitlessness remove and back, in a little more than one second. Our testing demonstrates that the lens concentrates mechanically. The channel ring of the lens does not pivot while centering, and the lens is calm amid center operations; also, full-time manual centering is accessible, by simply turning the center ring whenever.
The genuine story behind the 300mm ƒ/4 PF is its advancement in contrast with the past 300mm ƒ/4 AF-S: it weighed 1,440 grams (more than 50 oz) and was three crawls longer than the new PF rendition. The past lens wasn’t as confounded, be that as it may: it utilized just 10 components as a part of 6 gatherings, where the new PF variant uses 16 components in 10 bunches. In the accompanying lens piece outline, the green component is the Phase Fresnel component, and the yellow is the ED component.
The 300mm ƒ/4 PF is well-worked, with strong plastic parts and a metal lens mount. An elastic gasket covers the lens mount, shielding the lens from dust and dampness. The lens barrel is made out of a dark semi-roughed complete, and the elastic center ring demonstrates a furrowed example that is anything but difficult to grasp. The lens highlights nine adjusted stomach sharp edges to make up the opening for satisfying out-of-center results. Nikon likewise utilizes another opening control framework (the “Electromagnetic Diaphragm Mechanism”) which replaces the swishy mechanical control lever that you’ve seen on the back of each Nikon lens. We’ve done some testing and can affirm it will take a shot at Nikon cameras back similarly as around 2007.
Some worry has been noted about the Phase Fresnel lens component creating an odd bokeh, or poor execution as to lens flare: here are our lens professional Rob’s remarks from shooting his specimen photographs with the lens. “Flare is not an issue on this lens. Indeed, even with the lens hood off I didn’t see any odd reflections from the PF component.” Regarding bokeh, here is an example picture which will give you a sign of how it performs.
The lens bears a separation scale that is recessed and windowed, its markings set in feet and meters. There are no profundity of-field or infrared file markers. There are three principle switches in favor of the lens: self-adjust control, center limiter, and vibration diminishment control. Self-adjust control clearly permits the client to handicap self-adjust operations on the lens (checked to some degree confusingly as “A/M | M/A | M”). The center limiter is set for 3m, permitting the client to farthest point center between least center separation and 3m. At last, the vibration control capacity is somewhat not the same as we’ve seen in past Nikon lenses. The VR switch now joins the Normal and Sports modes and in addition OFF into its capacity. On other Nikon lenses, ordinarily when the VR switch is set to one side it turns VR on. This position will turn VR off on this lens. Simply know it may not resemble your different lenses.
