![]() But the image quality of the IQ4 back is still the best available in the world now, and XCD lenses can’t cover a 54x40 mm sensor. It can be a fun challenge like using a Leica to shoot moving subjects can be, but the long focusing throw of V lenses makes it difficult to know you will get the shot for sure. Overall, kudos to Hasselblad for more than half a century of outstanding lenses and cameras, and to Phase One's IQ4 back for continuing to offer a sensor of unparalleled image quality.Ĭlick to expand.For street or other moving subject photography, shooting with V lenses is a challenge. The substantial performance benefits of the IMX411 BSI sensor in terms of light sensitivity and detail capture is a reminder that a 44x33 mm IMX461 sensor, the cropped version of the 54x40 mm IMX411 sensor, in a future CFV-III-100c would offer a very nice step-up in image quality (hint hint, Hasselblad!). When examining the 100% crops, the 3x higher resolution of the IQ4's 151-MP IMX411 sensor is apparent, as well as the higher light sensitivity of its BSI architecture, with the IQ4 needing 1/2 to 1 stop of less shutter-open time or lower ISO to achieve the same overall exposure. Of course if you need autofocus, none of that will help you. Purely on image quality I would rate the 250/5.6 SA as the most optically impressive lens of this excellent bunch, because it is virtually free of any color fringing even in this very high-contrast scene, and captures a stunning amount of detail edge-to-edge. The XCD 135+1.7x TC performs like a premium 230-mm prime lens. Both XCD lenses are also outstanding, though I was surprised to see noticeable CA from the 80/1.9 at f/8. In general, XCD lenses are sharper, more contrasty (and more auto-focus-y than the V lenses, but these two V lenses are considered among the very best of the V lineup, and it shows. In terms of lenses, the decades-old Hasselblad V 100/3.5 and 250/5.6 superachromatic are outstanding performers. IQ4 + 250/5.6 SA CF f/8 (yes, that's a jet in the distance photobombing my test shot):īoth cameras and lenses can take excellent photos under these conditions.
