Mamiya’s DL28 Medium Format D-SLR; Digital Or Film, Take Your Pick Page 2
This highly flexible system accepts a wide array of lenses, including V-series Hasselblad lenses with an optional adapter (not tested), and many additional accessories. We spent most of our time working with the 150mm f/2.8. Aside from their surprisingly brilliant performance, we learned that these Mamiya digital lenses all employ a 16-bit CPU and are firmware upgradable—reaffirming that this system is a surefire way to circumvent obsolescence, at least for the foreseeable future.
Pro photographers, especially in studio work, tend to shy away from a “normal” lens, which is true for the 80mm in this format. So it’s no surprise that the 80mm kit lens was our least favorite and was used sparingly. More to the point, we all agreed that the 150mm was the perfect portrait lens, although the 120mm macro also came into play here. (Keep in mind that a sensor factor of 1.3x applies.) The crisp images that the 150mm and macro lenses delivered clearly impressed us, especially when the lenses were used stopped down. However, I should point out that there is observable vignetting with all the lenses we worked with when shot wide-open.
The 80mm lens has a ring-style MF/AF switch, whereas the 150mm employs a push/pull focus clutch mechanism. Reaching life-size magnification, the 120mm f/4 macro lens is a bit different, notably in that it offers only manual focusing—which is fine when shooting up close, but not always practical at greater shooting distances.
Using A Memory Card
Even though the Mamiya DL28 does not boast the largest sensor available in a back of this type, file sizes are unquestionably large (over 50MB uncompressed raw). And you have true 16-bit color capture (the typical high-end D-SLR only delivers 14- or 12-bit capture). Greater color depth means a more lifelike image.
Translation: for the Leaf back to capture images without hindering your workflow, especially in Burst mode, it mandates a SanDisk Extreme IV-equivalent UDMA CompactFlash card. And I’d recommend nothing less than 8GB for starters, unless shooting entirely in the studio. In which case, tether the camera to your computer with the supplied cable and shoot away, without any practical limitations. Interestingly, you can see the captured image both on the computer monitor and camera monitor when shooting tethered (it’s often an either/or situation with other cameras). There is a noticeable lag before the image appears on a monitor or the camera’s LCD, but you can continue shooting in the interim.
The Mamiya DL28 Experience
We found that manual focusing was silky smooth on the 150mm and 120mm lenses. The 80mm lens’ manual focusing performance did not compare.
One of our chief complaints was that the AF lenses lacked full-time manual focusing override. And we also noted a dearth of focusing points. Further testing revealed that focus tracking in continuous AF was poor when confronted by any lateral movement, even with runners at nominal jogging speeds a short distance away (16-bit CPU notwithstanding). And while on the subject of movement, we experienced considerable shutter lag, which made timing of the shutter release critical. This is not a camera I would use for sports photography. But then again, it was never really designed for that purpose. The problem was readily overcome under controlled studio shooting conditions, in experienced hands. This was evident whether we were photographing a highly animated baby or a dog licking a young starlet’s face.
The only area of disappointment was with color noise at high ISO levels (400 and especially 800), more than comparable ISO settings on 35-style D-SLRs. However, keep in mind that the back was specifically optimized for studio work under bright lights, where ISO 50 and 100 prevail—and there we had absolutely no complaints with respect to digital noise. At these ISO settings, images practically sparkled—we could definitely say that about the jewel-studded necklace.
Outdoors was where we got to test other aspects of the camera and lenses. The DL28 managed to deal exceptionally well with high contrast and bright snow (in the camera’s equivalent to Evaluative Metering mode). While we expected some loss of tonal detail, we were actually surprised at how remarkably little we did lose in both the highlights and shadows under those conditions. That said, it doesn’t mean that you won’t have to use exposure compensation—the camera’s metering system is not foolproof.
The Mamiya DL28 has the look and feel of a pro camera that inspires confidence, with matching performance. This is a camera with potential. By the end of the day, we all came away very favorably impressed by the DL28 experience.
