HHFS Images Using 12-100 f/4 PRO - Small Sensor Photography by Thomas Stirr

This short article features some sample HHFS (handheld focus stacked) images using the M.Zuiko 12-100 f/4 PRO IS zoom lens… captured at the Cambridge Butterfly Conservatory. These photographs demonstrate the old adage that the ‘best camera’ is the one that you have with you.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 38 mm, efov 76 mm, f/8, 1/100, ISO-3200, handheld in-camera focus stacking, cropped to 4106 pixels on the width, subject distance 355 mm

I wouldn’t have typically used the M.Zuiko 12-100 mm f/4 PRO IS zoom lens for this type of subject matter as my main objective that day was to capture some photographs of my granddaughters visiting the facility.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 50 mm, efov 100 mm, f/8, 1/100, ISO-5000, handheld in-camera focus stacking, cropped to 3531 pixels on the width, subject distance 360 mm

It has been about 5 years since I last visited the Cambridge Butterfly Conservatory and I had forgotten that the facility has a number of large, tropical insects and other specimens, on display in glass enclosures.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 47 mm, efov 94 mm, f/4.5, 1/80, ISO-4000, handheld in-camera focus stacking, cropped to 3000 pixels on the width, subject distance 580 mm

So, I did what I could in terms of choosing shooting angles to help minimize glare from the glass enclosures, and also dealing with the dark, and often uneven, lighting conditions.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 44 mm, efov 88 mm, f/8, 1/125, ISO-6400, handheld in-camera focus stacking, cropped to 3180 pixels on the width, subject distance 395 mm

As you review the EXIF data you’ll see that one of the images was captured handheld at ISO-1000. Higher ISO values that ranged from ISO-2500 to ISO-6400 were used for the rest of the sample HHFS images featured in this article.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 100 mm, efov 200 mm, f/4, 1/60, ISO-1000, handheld in-camera focus stacking, cropped to 3240 pixels on the width, subject distance 450 mm

Since my output was out-of-camera jpegs… as would be expected I used Topaz Denoise AI as part of my processing for all of the images in this article. It should be noted that I use a non-current version of this software.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 54 mm, efov 108 mm, f/5.6, 1/125, ISO-2500, handheld in-camera focus stacking, cropped to 4836 pixels on the width, subject distance 370 mm

I knew from previous experience with the M.Zuiko 12-100 mm f/4 PRO IS zoom, that it has a closest focusing distance of 0.15 metres. So… it actually can be a practical lens to use for close up photography.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 34 mm, efov 38 mm, f/4.5, 1/80, ISO-2500, handheld in-camera focus stacking, cropped to 4296 pixels on the width, subject distance 300 mm

The lighting was quite uneven in a number of the display cases which made getting balanced exposures a challenge. This led to me using DXO ClearView Plus in post with some of my photographs to help improve image definition.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 61 mm, efov 122 mm, f/5.6, 1/50, ISO-3200, handheld in-camera focus stacking, cropped to 4106 pixels on the width, subject distance 425 mm

As is my standard practice I only spent a couple of minutes in post with each of these handheld out-of-camera focus stacked jpeg files.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 86 mm, efov 172 mm, f/8, 1/125, ISO-6400, handheld in-camera focus stacking, cropped to 3744 pixels on the width, subject distance 440 mm

I used an in-camera focus stack of 12 images, utilizing a Focus Differential of 5, for all of the sample photographs in this article. Aperture was adjusted based on my assessment of the overall depth-of-field desired… given the composition, the subject distance, and lens focal length used.

OM-D E-M1X + M.Zuiko 12-100 mm f/4 PRO IS @ 66 mm, efov 132 mm, f/5, 1/100, ISO-4000, handheld in-camera focus stacking, cropped to 4872 pixels on the width, subject distance 400 mm

From time to time we may find ourselves in situations where we do not have the ideal camera or lens with us. All we can do is improvise the best we can with the camera gear that we have in our hands. Regardless of the gear we may own, understanding the capabilities and practical limitations of our camera equipment is very beneficial in these types of situations.

Technical Note

Photographs were captured handheld with the camera equipment noted in the EXIF data, and using single point auto-focus. All images were created from out-of-camera jpegs using my standard process in post.

All photographs were created using handheld in-camera focus stacking. A stack of 12 images with a Focus Differential of 5 was used for all of the sample photographs in this article. This is the 1,401 article published on this website since its original inception in 2015.
