A number of days in the past, Ricoh filed a patent utility in Japan for 3 new full-frame telephoto lenses, one in all which is for mirrorless cameras. These aren’t the primary they’ve filed, both, having filed patents for a few different mirrorless lenses a month in the past. Might this be a turning level for Pentax, the one firm that’s been holding onto DSLRs for pricey life whereas the remainder of the world goes mirrorless?
The three new lenses described by the patent aren’t significantly excessive finish. They’re all variable aperture, though the one for mirrorless has a max variable aperture of f/2.8-4, so not too horrible. It’s uncertain, although that Pentax is planning to pursue the mirrorless market. A minimum of, not but.
70-300mm f/4.5-5.6 (for DSLRs)
Focal size: 72.08-291.32
F worth: 4.6-5.7
Half angle of view: 17.2-4.2
Picture peak: 21.64
Total size: 190.18-259.23
Again focus: 42.56-66.55
100-400mm f/4.5-5.6 (for DSLRs)
Focal size: 103.00-388.00
F worth: 4.6-5.7
Half angle of view: 11.7-3.1
Picture peak: 21.64
Total size: 234.40-340.41
Again focus: 55.31
100-300mm f/2.8-4 (Mirrorless)
Focal size: 103.00-292.00
F worth: 2.9-4.1
Half angle of view: 11.9-4.1
Picture peak: 21.64
Total size: 259.72
Again focus: 18.00
The apparent giveaway on that final one being a mirrorless lens is that 18mm flange distance. It’s bodily unattainable for a DSLR to have one which brief as a result of measurement of the mirror.
In fact, it’s fully potential that Ricoh is designing this lens for any person else – assuming it ever really involves fruition – they usually’re not planning to go mirrorless in any respect (which is what Asobinet believes). However, the thought of Pentax lastly caving and going the mirrorless route is sort of fascinating. They do have a few fascinating improvements of their DSLRs that might probably apply properly to mirrorless, particularly if they aim the comparatively untapped mass client market.
