Two days early, the press launch particulars of the approaching RF 1200mm f/8 L IS USM leaked, and there are a number of nice surprises. First amongst them is that the lens weighs only a bit extra the RF 600mm f/4 lens, which is already very gentle for that focal size. An individual Digicame-Data believes was the writer of the now-defunct Nokishita weblog posted posted the press launch detailing the specs.

The minimal focus distance (MFD) is 4.3m, additionally roughly the identical because the 600mm f/4, which suggests its most magnification will probably be twice that of the smaller lens. Doing the mathematics, because of this a human head would utterly fill the body at MFD.

Not famous on the discharge are the lens dimensions.

For these with a glutton for focal size, the 1200mm lens does take each the 1.4x and the 2x teleconverters, rendering as a lot as a 2400mm f/16 equal lens. After all, the air column in entrance of that lens will chip away at sharpness. Stabilization turns into troublesome at these focal lengths. At f/16, diffraction results can rob a picture of sharpness and element.

With yesterday’s leak of product pictures and the small print from this launch, it seems Canon is placing out EF-style optical tubes, with out the additional RF ring featured on different white L lenses just like the 100-500 and 70-200.

Optical stabilization is rated to 4 stops (one fewer than had with the RF 600mm f/4), however that stat had an asterisk affixed to it. It has the usual three IS modes, and Canon’s most up-to-date lens coatings.

With the burden being so comparable, in addition to the minimal focus distance being virtually equivalent, one may suspect this was an RF 600mm f/4 dressed up with an connected teleconverter-like group of parts. The 1200 is to have two giant fluorite parts, one Tremendous UD aspect, and a single UD glass aspect. Whereas the lens parts are listed and emphasised in another way than was finished with the discharge of the RF 600mm, a Canon Rumors discussion board member identified that it doesn’t eradicate the chance that the larger finish of the lens could possibly be largely the identical because the RF 600mm f/4.

The total launch, full with weasel phrases and footnotes, is rumored to be coming on Thursday the twenty fourth.
