P40+, P65+, H3DII-50, Aptus-II 10

The Phase One P65+, Hasselblad H3DII-50, and Leaf Aptus-II 10 are the highest resolution backs currently shipping from their respective manufacturers. We recently had all three in our studio (along with a P40+) so we took the opportunity to shoot a comparison. These images were captured on a heavy tripod with mirror up and self-timer within a few minutes of each other. Each was opened in the current (as of the day of the comparison) version of it’s native software (Leaf Capture 11.2.8, Capture One 4.8.3, and Phocus 1.2.1) and processed with default settings.

As always, we welcome any photographer to use our facilities and equipment for their own testing – no test will ever be as relevant to you as the test that you run yourself.

Additional notes:

Capture Integration strives to provide fair and balanced testing. However, controlling every variable is simply not possible. In this test the lighting changes were a natural consequence of changing cloud cover. We made a strong effort to use the same focus point for all four systems. In each case the focus was manually thrown off and then single-point AF was used with the camera on a tripod to focus on the beige  apartment buildings directly to the right of the red-roofed guard-house on the middle bridge (the Venetian Causeway). The camera was then placed in manual focus and the scene recomposed to the framing seen. Also, we are a major dealer and have a variety of gear on hand at any given moment. However, much of our equipment is on rental, or being used for demos in our studio or on location; therefore we can’t always do tests with the exact same body and lenses. In this case we had the ability to match focal lengths (150mm) by using the P65 and P40 on a Phase One body with a 150mm D lens and the Aptus-II 10 and H3D on H bodies with their HC150mm lens.

Tethered Showdown: Canon 1Ds Mark III vs. Phase One P30+

UPDATE: Since this test was done OSX has seen a major boost in USB performance which has made tethering to the 1Ds Mark III much faster. Please see the Canon Test page for the Canon 1Ds Mark III in OSX 10.5.6 vs 10.5.5 benchmarks.

Many photographers use tethered capture as their primary workflow. For these photographers the speed of a tethered setup is critical. For this test we are defining these aspects of speed in a tethered workflow:

Capture-To-Preview: the time between the end of the shutter release and the display of a preview image. In Capture One this is measured as time until the high-res preview rather than the low-res preview that is initially displayed.

Max Sustained Speed: shot-to-shot time that can be sustained (i.e. the fastest speed without filling the buffer)

Burst Lag: time needed to display the last shot of a burst (i.e. time needed to clear the buffer)

Burst Speed: maximum frame rate possible, measured in seconds per frame (spf)

Shots / [# of seconds]: maximum number of shutter releases during a particular time-frame. This is measured by shutter releases, not previews shown, so with the 1Ds Mark III many images remain in the buffer (see Burst Lag).

Results Summary

Type of Speed	1Ds III [Raw, DPP]	P30+ [Raw, C14]	Faster	Dif. of Speed
Capture-to-Preview	9.5 sec	2.6 sec	P30+	3.7x as fast
Max. Sustained Speed	3.3 spf*	1.5 spf*	P30+	2.2x as fast
Burst Lag	50 sec	3.5 sec	P30+	14.3x as fast
Burst Speed	0.2 spf*	1.5 spf*	1Ds III	7.5 x as fast
Shots / 60 seconds	27	42	P30+	1.6x as fast
Shots / 120 seconds	45	83	P30+	1.8x as fast

*spf = Seconds per Frame, or the inverse of Frames per Second (fps)

Results Graphs

*Due to a change in Canon’s SDK, Capture One 4.1.1 cannot tether directly to the Canon 1Ds Mark III. Instead this test was done using Capture One 4.1.1’s “Hot Folder” option to tie Capture One to a Capture Folder managed by Canon’s DPP Software. The result is a delay of approximately 2 seconds from the shot to the preview, but the delay is not cumulative.

Note: The 1Ds Mark III had only transfered 13 of the 27 images at the end of 60 seconds. Another 50 seconds was required to transfer the final image. The P30+ had transfered all but one image at the end of 60 seconds requiring only an additional 3 seconds to transfer the final image.

Note: The 1Ds Mark III had only transfered 27 of the 45 images at the end of 120 seconds. Another 52 seconds was required to transfer the final image. The P30+ had transfered all but one image at the end of 120 seconds requiring only an additional 3 seconds to transfer the final image.

Testing notes

Software: Capture One 4.1.1, EOS Utility 2.3

Hardware: Mac Pro 3.0 Ghz Eight-Core with 7gb of Ram

Tethered setup: shooting to a folder on the main hard drive*

*performance might improve slightly if the capture folder and operating system are on different internal hard drives
