Pushing the Limits

It was very early morning when we spotted this young lion. He has been through some territorial fights - see the scars. The sun had not risen and I was not sure if I could get a decent image. Captured with the Panasonic Lumix S1R and the S Pro 70-200 mm f/2.8 lens. I had the ISO on "auto", and I set the shutter speed to 1/160 sec (i wanted to be as close to one over the focal length I was at). The focal length was at 130mm. The aperture was set at f/2.8 and the camera set the ISO to 16000. Typically I set the limit at ISO 6400 but there would be no image at that sensitivity.

The image a direct conversion from RAW to JPG - no adjustments at all except a crop for composition. The noise reduction is at 0, sharpening at 0. Image processed using Capture One 12.

Lumix S Pro 70-200 f/2.8 hand-held

Zebra Family at Sunset

One of the greatest features of Lumix cameras, the G and the S series is the incredibly good image stabilization. On the S1R was rated at 6 stops. With firmware version v1.1, the in-body IS system will reduce shake by an additional 1/2-stop, for a total of 6 stops with non-stabilized lenses and 6.5 stops with Dual IS-compatible glass. With the new S Pro 70-200 f/2.8, the stabilization is rated at 7 stops.

This image was captured hand-held with the S1R and the S Pro 70-200 and a 2X Teleconverter. The combined focal length was 400mm. Exposure triad f/5.6, 1/125 sec, ISO 800.

My impressions of the new 70-200 mm L mount zoom lens - LUMIX S PRO 70-200 O.I.S (S-E70200)

I had the pleasure of using two of these lenses, albeit pre-production, with two Lumix S1R bodies while on my trip to Tanzania. I used these with and without the 1.4X and 2X teleconverters in order to extend the reach as needed. With the high resolution of the S1R cropping is a viable option.

The Pro S 70-200 has one of the best image quality performance I have seen in a zoom lens in the range. The lens surely must meet or exceed certain stringent standards to be certified by Leica.

Exposure triad f/63, 1/500 sec, ISO 2000

Tech details: 22 elements in 17 groups, the use of 2 UED (Ultra Extra-low Dispersion) lenses, 3 ED (Extra-low Dispersion) lenses. Magnification .21X with a close focus distance of .95m. Focus range switchable from Full to .95m-5m and 5m to Limit. The lens is 208.6mm (8.2 in) long with a max diameter of 94.4 mm (3.72 in)and weighs 1,570 gm (3.46 lb). Filter diameter 82mm. It is dust and splash resistant and has a working temperature range of -10 C to 40 C (14 F to 104 F). The focus speed is rated at 0.12 sec. at the extended focal length of 200 mm. It has a focus clutch to allow manual - autofocus switching and the lens barrel has three programmable focus buttons. Dual IS - when coupled with a Dual IS2 body the overall image stabilization is rated at 7 stops. The provided lens collar has an Arca Swiss compatible foot.

Superb detail and dynamic range

I found that the lens had exceptional focusing speed and now understand why. The lens uses a double focus system. A large linear motor is used for long-throw adjustments and a stepper motor is used for small incremental strokes. All focusing is internal and the focusing lenses are light so as to allow rapid movement during focusing. The focus frame rate is 480 FPS and the lens tracks subjects incredibly well. This combination clearly has the fastest focusing I have experienced in the Lumix lens line-up. The close focus distance is .95m or about 3 feet. Even at this close range, there is no visible distortion. in-fact the has little to no distortion over its entire zoom range even wide open at f/2.8.

Smooth focus fall-off.

For the duration of the Tanzania safari, I never mounted either S1R on a tripod or any other clamp or mount. All images were captured hand-held and the image stabilization was amazing even at slow shutter speeds.

Note: Some images have been cropped and some have a vignette applied for presentation purposes.

Lumix S1R test - Red Arrows - North American Tour

8 of the 11 Red Arrows in formation over Boston Harbor

Royal Air Force Aerobatic Team Red Arrows are on a major tour of North America.  This is the first in more than a decade.  It is intended to promote the best of British and deepen partnerships .

The Red Arrows are on an 11-week North American tour that started in Halifax, Nova Scotia July 8 and will end in Rapid City, South Dakota Oct. 8, 2019.

The aircraft are BAe Hawk T Mk1, a two seater trainer jet that has been replaced by the new Hawk T Mk2.   However, the Mk1 will remain in service for another 10 years. Like the Mk2, the Mk1 is a fully aerobatic, low-wing, transonic, two-seat training aircraft that is still used in a number of roles for the RAF. 100 Squadron, based at RAF Leeming.

The show started about 20 minutes later than expected and unlike the flight path that was released the jets flew a completely different route.

My aim was test the performace of the continuous focus capapbility of the Panasonic Lumix S1R in a high speed fly by. The lens I used was the Lumix S Pro 70-200 f/4. The aperture was set to f/8 and the shutter speed was 1/2000 to freeze motion. The ISO was set to auto and resulted in ISO 250 to 320 for the incoming shots and 640 to 800 for the outgoing images. The focus was set to continuous, drive mode on high and the focus area "Zone Oval".

There are two sets on images - 20 incoming and 20 outgoing. All images are from single bursts in the exact sequence and unedited. The RAW files were converted and exported to JPG using Capture One. As you will see from these images, the camera and lens performed exceptionally well in maintaing focus.

This the incoming gallery
