![]() That of course takes time and I can see real benefits in the feature for those trying astrophotography for the first time. For milkyway images I have not found it difficult to focus, just use live boost and magnify x14 to a star and adjust to its smallest. I assume that the focus lock would remain unchanged during those 60 secs. What I would be interested to know is ġĜan you use the Starry Sky AF feature using the menu system within Olympus Capture?Ģ Will the Starry Star AF refocus for each exposure when setup in the sequencing menu of Olympus Capture? Of course during this time there are several battery changes so the USB charging ability would solve changing batteries. Sometimes over an imaging session (can be several hours) the focus drifts. I then fine tune by taking an image and having software measure its HFR. Usually by first using a Bahtinov mask and the live boost mode which is not that effective. I take some considerable time to set the focus. I use Olympus Capture to take the images via the sequencing tab. I set the camera and lens on the mount connected via the USB (using an extender) cable to my laptop via a 30m cat5 cable. I do a lot of deepsky imaging with my MKII the 300mm and MC14 on a tracking mount. One is the Starry Sky AF and the other is the ability to power the EM1 MKIII from the usb cable. There are two features of the MKIII that would tempt me to upgrade my EM1 MKII. Hi Peter and thanks for the review particularly on the Starry Sky AF. Time Lapse - Maximum number of shots is now 9 999, up from 999.With the Mark II and 1X the maximum live comp recording time is 3 hours. Live Composite - record for up to 6 hours.Improved Face / Eye Priority AF - Improved AF algorithms allow for better face/eye priority auto focus and tracking in situations that were more challenging previously.Shutter Life - The shutter is rated at 400 000 actuations. ![]() Charging can now be done in camera using USB-C cables, and can be charged via a portable USB-C PD power bank or battery pack Charging - the Mark III uses the same battery (BLH-1) as its pre-cursor and the 1X.Better dust reduction - a new dust resistant coating on the sensor reduces spots in images by 90% over the previous coating on the Mark II.Improved In-body 5-axis image stabilization - up to 7.5 stops of compensation with Sync IS compatible lenses, and 7.0 stops with all other lenses.It's worth mentioning the other features/improvements to the E-M1 Mark III and also worth noting that most of these are inherited from the E-M1X. Accuracy Priority uses a fine-tuned focus scan and is effective for shooting specific stars with telephoto lenses." Thanks to the powerful image stabilization, this feature makes handheld astrophotography possible using a wide angle lens. Speed Priority mode (default setting), which prioritizes focusing speed and complete AF operations in a short period of time. A new algorithm was developed to offer accurate focusing even on the tiniest stars shining in the night sky, enabling ultra-high-precision autofocusing that has been admired even among professional astrophotographers. ![]() In the past, photographers have traditionally relied on manual focusing. Here's what Olympus says about the feature, "Starry Sky AF, which is new for the OM-D E-M1 Mark III, is a feature that will revolutionize the world of astrophotography. Even with the manual focus assist features on previous OMD models there have been numerous times where I thought I had nailed the focus while out in the field, only to discover that, once I viewed them on my computer monitor, the focus was a bit soft. Regular auto-focus doesn't work in dark conditions, which means you need to rely on manual focusing. If you are not an astro-landscape photographer, you may not think this is a big deal, but believe me - it's out of this world! One of the most challenging aspects of night sky shooting is the difficulty of focusing on the stars. The feature that I am most excited about in the E-M1 Mark III is Starry Sky AF.
