Cambo WRE-CA Lens Adaptor

Cambo WRE-CA Lens Adaptor

Cambo announces the new WRE-CA lens adaptor is now available.  This new adaptor enables photographers to attach Canon EF lenses to the pancake style Wide RS system when using a digital back with a rolling shutter, such as the Phase one IQ3-100.

Photographers that already own a Canon wide angle lens such as the 17mm TSE will benefit when using the lens adaptor as the image circle is large enough to cover the 40x54mm sensor area. Check first with your local dealer regarding lens image circles.

The WRE-CA locks onto the WRS body as you would mount a Schneider or Rodenstock lens. The Canon lens bayonets into position just the same as a regular Canon lens mount.

The ES (Electronic Shutter) of the Phase One IQ3-100 provides control and versatility when used with a technical camera like the Cambo WRS. It enables instant access and control of the shutter speed and ISO. There is no electronic link between the camera body and lens however you can enter the aperture value manually on the IQ3-100 for meta data proposes.

A black reference is captured prior to you image capture. When using the IQ3-100 the Live View makes it easy to compose your frame and ensure perfect focus. You can also capture direct in Live View using the shutter release overlay or return to the ES control menu to activate capture.

Operating the Lens Adaptor

Normally when a Canon auto iris lens is removed from a DSLR camera body the lens aperture remains wide open. The WRE-CA communicates with the lens and enables the user to adjust the aperture, giving you full control.

Dial in the maximum (wide open) aperture to focus, then select the desired aperture for the shot. You then have the option of stopping the lens down to check depth of field. When the aperture is dialled in it will be displayed in the window after the focal length of the lens. The communication is accurate, such that the display will also show the focal length of zoom lenses.

As you can see from the GIF above the focal length is shown together with the selected aperture. This sample file was created when using a Canon 17-40EF-L lens.

This adaptor has an internal battery for continuous use and features an OLED display which shows the preset or set aperture together with the focal length of the lens. A Powerbank and mini USB cable is supplied for additional power on location.

The adapter accepts lenses fitted with Canon EOS bayonet, in combination with the WRS technical camera. The WRE-CA adaptor is finished in black to match the Cambo camera versions.

New Cambo Actar 90mm – Stitching Images

New Cambo Actar 90mm – Stitching Images

We’re back out on location at one of our favourite spots, to show comparison captures using the new Actar lenses. This time we are using the Actar 90mm f4 lens, which has a very large image circle of 90mm.

actar 90mm charlestalks

As with all Actar lenses the 90mm is supplied fitted with a lens plate that slots directly in the front standard of the Cambo Actus camera platform. It is compatible with Mirrorless and DSLR camera systems. The large image circle of 90mm enables you to shift the camera body 27mm left and 27mm right, a huge 54mm shift. For my test we captured an image with 20mm shift left and right, producing a very nice, sharp, wide and distortion free image.

actar90lens

Again you need to find the infinity of the lens but this is easier to achieve as its a longer lens. Weather permitting our next location shoot will explain this process.

For this test we used the following; Cambo Actus Mini View Camera, Sony A7R, Actar 90mm lens, Standard bellows, CBH-6 ball and socket head and Manfrotto 055 CF tripod.

Using the Sony to meter the exposure at ISO50 was 1/8th sec at F16. The RAW file was captured with the generic Sony profile and a 2 second self timer was used to avoid camera shake.

C1colourbalance

Having used Capture One with Leaf digital backs, its very easy to process the Sony RAW files with Capture One Sony Express. I tweaked the exposure +0.3 and selected the Sony Generic profile, this time I chose 8Bit Adobe RGB file output and saved each file as a TIFF to preserve the data. Capture One pre-set sharpening was used, there was no need to increase this as the images were already sharp.

C1process

The Photoshop layered file stitched is 870.7MB, the image file size is 188.3MB. The pixel size dimension of the capture is 13422 x 4904 at 300dpi / Print output 44.74” x 16.35” 300dpi.

actar90mm_pan3

The Photoshop CC2015 auto merge, content aware and edge fill process was the same as when we processed the Actar 24 and 60mm files. Having used Photoshop since v1 the workflow process is incredibly slick, especially when using MacBook Pro with SSD drives.

The images we use for the blog are 1080 wide at 72dpi, reduced to manage on the blog. 

Image quality from the 90mm is very good. As you can see from the cropped image, this is 100% zoom, its sharp and the colour is good. More importantly I didn’t find any lens aberration, commonly known as colour fringing, from the middle to the edge of the frame.

Cambo Actus – Rear Camera Mount

Cambo Actus – Rear Camera Mount

Cambo continues to develop the Actus camera system by customising the rear standard at the request from a photography school.

Actus Camera Mount

The cool thing here is that – you can also adapt this to the Actus system making the Cambo a very flexible solution and continuing their “Modular” way of thinking – fantastic!

Actus Camera Mount

Fast Exchange

You need a technical camera to teach product photography by using the Scheimpflug rules. Many schools require students to use their own camera systems so when it comes to changing from a Nikon, Canon, Fuji, Sony etc… the mount on the rear standard has to be changed – this can be a challenge if the mount has to unscrewed each time – but this is not the case with this customised solution.

Actus Camera Mount

Actus Camera Mount

As you can see the rear standard splits into two parts. The top part has the camera mount ; Nikon, Canon, Fuji, Sony etc… meaning the students can use one technical camera but with many different camera systems. The bonus for the school is that they only invest in one type of camera system.

Using the Cambo Actus and Zeiss Otus Lens

Using the Cambo Actus and Zeiss Otus Lens

Michael Jones is a professional photographer based in Oregon USA. He is experienced at working in every camera format, whether digital or film, Michael is skilled, capable and inventive, without needing to rely on heavy retouching or a single stylized look. This versatility allows him to fully collaborate with you and to easily resolve glitches that may surface during the shoot. While known for his elegant lighting constructs, Michael can be easily as effective behind the camera shooting with natural light.

Michael Jones

“I own the ACTUS and am using it with the Sony A7R2 and the Canon AC-CA lens adapter and am very curious about using wider angle lenses.”

Michael Jones

“Here is an example from an assignment this summer for a Daimler owned company where I used the combination of the ACTUS, Sony A7R2 and the Zeiss Otus 28mm. It allowed me to shoot at f6.3 at 100 ISO in darkened conditions with strobe and keep the truck and car sharp with a minor shift, tilt and rise on the ACTUS.”

Michael Jones

Many thanks to Michael for his feedback and images. You can find more of his work here; www.michaeljonesphotostudio.com

We’ll feature more photographers working with Cambo camera systems next year. Sign up and don’t miss a post. For further information about Cambo products contact your nearest dealer– Dealer Search.

Fuji XPro2 – Image stitching with the Cambo Actus

Fuji XPro2 – Image stitching with the Cambo Actus

During one of the Calumet Open days we had the opportunity of shooting with the Fuji XPro2. This camera has been a huge hit with photographers working in most fields of photography.

The equipment used for this test shot was; Cambo Actus Mini View Camera platform, Cambo Actar 24mm lens, Standard Bellows, Fuji XPro2, and CBH-6 Ball head fitted to a Gitzo tripod.

Charles Woods

Camera mounts can easily be exchanged on the Actus, simply remove four screws, fit the Fuji-X mount and replace the screws.

Actus Fuji Actar 24

As it was an open day we had little time to do this and shot 3 images, to produce a wide shot which we later stitched using Adobe Photoshop CC 2105. This is a single image captured showing the angle of the lens prior to any further work or stitching.

Actus Fuji Image

Each jpeg file captured is 4.1MB 6000×4000 pixels 68.7Mb. When working with Photoshop the stitched file is 179Mb with the dimensions 15397 x 4064 pixels (543.17cm x 143.37cm) at 72dpi.

Acts & Fuji XPro2 Stitched Image

As you can see from the screen grab, the lens is pretty sharp and shows good detail and tone range. Of course using this size sensor we could have captured more images to stitch if required.

Cambo Actar 60mm – Stitching Images

Cambo Actar 60mm – Stitching Images

Following on from our shoot with the Actar 24mm, we were in a good location to capture images with the recently launched Actar 60mm f4 lens.

Within half an hour of shooting with the 24mm the light turned golden and although it looked warmer, trust me it was much colder!

charles2 The Actar 60mm is supplied fitted with a lens plate that slots directly in the front standard of the Cambo Actus camera platform. It is compatible with Mirrorless cameras. The large image circle of 75mm enables you to shift the camera body 19mm left and 19mm right, a huge 38mm shift producing an effective 66mm x 54mm stitched sensor capture – as its a longer lens there is not the distortion effect you obtain from a wide angle lens.

actar 60mm lens

Actor 60mm f4 Lens

Again you need to find the infinity of the lens but this is easier to achieve as its a longer lens. We will be covering this soon, a short video will explain the process.

For this test we used the following; Cambo Actus Mini View Camera, Sony A7R, Actar 60mm lens, Standard bellows, CBH-6 ball and socket head and Manfrotto 055 CF tripod.

Using the Sony to meter the exposure at ISO50 was 1.0 sec at F16. The RAW file was captured with the generic Sony profile and a 2 second self timer was used to avoid camera shake.

actar60mm_main

As already mentioned the lens image circle is quite large, 75mm, so can be shifted horizontally 19mm left and 19mm right. For this test we shifted 10mm left and 10mm right. Again we chose not to use the rise and fall as the ground and sky wasn’t very appealing.

Once the RAW files were captured we imported the files into Capture One Sony Express and processed them using the Sony Generic profile, 16Bit and saved as a TIFF file to preserve the data. Capture One pre-set sharpening was used, as shown below, there was no need to increase this.

actar60mm3up

The only real change was the warmer natural light, so we enhanced the contrast to keep as much detail in the image. I prefer the warm light, its much more pleasing to the eye.

The Photoshop layered file to be stitched is 929.8MB layered file, 322MB (flattened.) The TIFF file is 1.24GB. The pixel dimension of the capture is 11456 x 4912 at 300dpi / Print output 38.18” x 16.37” 300dpi.

actar60mmpanorama

The Photoshop CC2015 auto merge, content aware and edge fill process was the same as when we processed the Actar 24mm files.

The images we use for the blog are 1080 wide at 72dpi, reduced to manage on the blog. The cropped imaged was taken from the middle of the panorama at 100% (approx.) zoom. The file is 8.8MB, 1893 x 812 at 300 dpi with a print output of 6.31” x 2.7” at 300dpi. I have been too generous with the crop produced by the Actar 24mm as the size of these files should be the same.

actar60mmpancrop

The Actar 60mm is a better lens for this type of work. Of course longer lenses will suffer less with distortion and lens aberrations, we are also cropping into the image area which is far more effective when shooting a panoramic image.

There is more to come – we can’t say too much just now, so please Sign up and don’t miss a post. For further information about Cambo products contact your nearest dealer– Dealer Search.
