D-SLR Digiscoping- Get closer to the action with our range of high quality and easy to use Kowa digiscoping adapters

What is digiscoping? 

Digiscoping is the method of attaching a digital compact camera or DSLR, video camcorder or phone to a spotting scope to create very highly magnified images or video. By combining the optics of a spotting scope with the optics of a camera  - the telephoto power of a Kowa digiscoping set-up can far exceed that of traditional telephoto lenses as well as often being far more compact.

Kowa offers a range of digiscoping adapters to suit all applications. When combined with our legendary range of super high quality spotting scopes – with practice, the results can be truly spectacular. Our digiscoping adapters are designed to make digiscoping easy and connect to our spotting scopes quickly and securely.

We currently have two digiscoping adapters for D-SLR digiscoping.


1. The Kowa TSN PZ Telephoto adapter transforms your KOWA TSN 880/770 series spotting scope into an extremely high quality telephoto lens for your D-SLR camera. Allowing you to not only experience stunningly sharp views of the world around you, but also take exceptionally detailed and vibrant photographs and videos with your D-SLR camera.


In contrast to conventional digiscoping, where the image produced by the spotting scope eyepiece is photographed, the TSN PZ connects your D-SLR directly to the body of the scope via a T2 mount. This makes for a high powered, yet lightweight and compact telephoto lens, when compared to traditional telephoto lenses.

The TSN PZ has a variable focal length range of 680mm – 1000mm (based on 35mm), which gives you the added flexibility when composing your image. It also makes finding your subject matter easier – by zooming out to the wider angle of 680mm to locate the subject and then zooming into 1000mm for maximum telephoto power.


Focus is achieved by using the responsive dual manual focus wheels on the scope body. Incorporating quick and ultra fine focus options, you are in full control of focussing.

No more frustrating auto-focus hunting. The decision is yours, quickly and accurately manually focusing on even the most challenging of subjects.


Please note: When used with full frame D-SLR cameras, significant vignetting will occur.

2. The Kowa TSN-PA7 D-SLR digiscoping adapter transforms your KOWA TSN 880/770 series scope into an extremely high powered telephoto lens for you D-SLR camera. Allowing you to not only experience stunningly sharp views of the world around you, but also take highly magnified, detailed and vibrant photographs and videos with your D-SLR camera.

In contrast to conventional digiscoping, where the image produced by the spotting scope eyepiece is photographed. the TSN-PA7 connects your D-SLR directly to the body of the scope via a T2 mount. Creating a high powered, yet lightweight and compact telephoto lens, when compared to traditional telephoto lenses.
Designed to be used with the Kowa TE-11WZTE-10Z zoom eyepieces and Kowa TSN-880/770 series spotting scopes. The design allows for the full use of the zoom eyepiece range giving an amazing focal length reach of up to 2570mm when using the TE-11WZ eyepiece or 2750mm with the TE-10Z.

Due to the unrivalled high magnifications that can be achieved in digiscoping, it can be a challenging but also very rewarding method of telephoto photography. Try these useful tips to help you get the best from your digiscoping.

Even the slightest movements can cause camera shake resulting in blurred images, try setting your D-SLR to mirror lock-up – this will help reduce vibrations when the shutter is fired.

A sturdy tripod with a good, smooth video panning head is highly recommended to keep your digiscoping setup stable.

Use your cameras self timer or a remote control to fire the shutter of your camera, the less you handle your camera whist taking the shot, the less the risk of camera shake.

Good light is essential in digiscoping resulting in faster shutter speeds to help freeze the motion of your subject and minimise camera shake.

A walk on Anglesey, who knows what you’ll see?

Rob Wilton explain why he never leaves his binoculars at home…


There’s something magical about walking on Anglesey. To me, the light and atmosphere just seems different, with its rugged coastal cliff paths, expansive woodland, salt marshes and unspoilt beaches lines with ancient sand dunes.

Sometimes I can walk for miles and not see another soul- the only reminder of civilisation being an ancient burial chamber or monolith which has stood on the landscape for thousands of years- a landscape that you can imagine as you stand there, hasn’t changed much over the centuries.

These expansive panoramas are usually enhances with the stunning backdrop of the mountains that make up the Snowdonia National Park on the Welsh mainland. Depending on what time of the day you see them, their appearance can look remarkably different, sometimes dark and forboding and at other times, soft hues of pink and purple fading away into the distance.

It’s why I spend most of my free time there, why I’m prepared to leave my snug warm bed at 6.00 a.m and why I’ll walk for miles until my legs ache with Dougal my Springer Spaniel- we just can’t get enough of the place! when you walk through the wide range of natural habitats on the Isle of Anglesey you can’t help but be the surrounded by the diverse range of wildlife that it supports. From vast seabird colonies to the many species of whales and dolphins that populate the coast line. It’s this amazing array of animals that always has me reaching for my binoculars before setting off on a trek. My binoculars are as important to me as my bottle of water, map and compass. They enhance every walk, help me to engage deeper with my surroundings and fill me with lasting memories. Memories which I might have missed without them.

I’ll take you back to a walk I experienced a few weeks ago on one of my favourite stretches of Anglesey coastal path, which I know just wouldn’t have been the same without my binoculars. The amount of wildlife I witnessed was breathtaking. I stopped for a well earned rest and sat on a rock viewing Grey Seals on the bay. Observed a Kestrel feeding her young inside hole in a rock on a distant cliff face and saw a silhouette of a bird of prey perched on a boulder. It was only after sighting it through my binoculars that I realised it was a stunning Peregrine Falcon.

As a walker you don’t want to be burdened with a large binocular weighing you down, use a heavy bulky set and it will probably mean you decide to leave them behind more often than not. That’s why I’m loving my new Kowa BD XD binocular. Kowa have managed to create a really compact model without compromising on optical quality. In Simple terms, it means I’m getting the superior light gathering power and resolution that a much larger binocular would normally offer, but in a far more compact and lightweight body. They sit over my shoulder and I don’t know they are there- perfect for walking.


They are stunningly sharp which makes viewing wildlife an absolute pleasure.

I love Orchids and Anglesey has lots of species, so I always look for a binocular which close focus capabilities- the new Kowa BD XD model focuses down to 1.5 meters! I can look at every petal in glorious detail just from standing on the path- no need to get into uncomfortable positions to see their beauty, plus I don’t risk trampling in amongst the flowers and treading on them- something I feel strongly about. Train them on a butterfly and you’ll get a detailed glimpse in to mother nature’s world of vibrant colours, patterns and symmetry on a miniature scale.

Over the years, walking in bad weather has never been an issue, and believe me, I’ve experienced my fair share of it on Anglesey. In fact for me walking in blustery wind and rain has a life enhancing effect- it heightens the senses and makes me feel alive- maybe it’s just me? But if you share this way of thinking or simply get caught out by a passing storm, make sure your binoculars are up to the job. my Kowa BD XD are magnesium allow and fully waterproof. I don’t have to worry about how they will perform, even in the most severe weather conditions.

One last thing I think is the icing on the cake. Kowa have developed an adapter for the iPhone and Galaxy4S which simply pushes over one of the eyecaps on the Kowa BD XD binoculars. So now, not only I can get amazing views of the wildlife, I can take a magnified picture of it too! It’s so easy- and the results can be truly amazing. No need to carry an extra camera kit- my phone is always with me, but now it’s a phone that doubles up as a camera with a telephoto lens sitting in my back pocket. What better way to spend an evening down the local pub with a real ale, reflecting on the highlights of the day’s walk and thumbing through the images I captured along the way?


If you love walks amongst our wildlife- you’ll love Anglesey. It has something for everyone, old and young, for the relaxed as well as the more adventurous- just don’t forget your binoculars, you never know what you might see along the way.

A wildlife photographer’s desire to do more

Rob Wilton explains what wildlife photography means to him

Anyone who photographs wildlife knows how challenging it can be, they will also know it’s often worthy of the effort required and that the rewards can be great, for me not material rewards, it’s more about rewards that reach my soul, happy memories and a sense of pride in my work.

It’s mental and often physical challenge- early starts, long waits, blurred images, frustration and missed opportunities. On the Physical side- heavy, bulky equipment, long treks and a painful choice of what gear to take and what to leave home.

It’s a challenge, but one that I relish.

I guess you could say I’m an opportunist, I struggle to sit in a hide for hours waiting for my subject to (hopefully) show up. I much prefer a bracing walk in the country side with my gear on my back and in my hands- if I’m fortunate enough to meet some wildlife on the way then I’ll do my thing. For me it’s more rewarding, I have to act fast, get into position, I need to focus and go for it.

Yes, it can be demanding and I know I may sometimes miss that perfect shot- but when I look back at my images and show them to family and friends, I feel a sense of immense achievement- I did this- this was my challenge, my image and it was worth it!

That’s where the Kowa Telephoto lens plays its part. I’ve used lots of telephoto lenses in the past, but this one is different.


It’s hard to explain, but it feels like an extension of myself, I control the lens, it doesn’t control me- I create the picture the way I see it in my head before I press the shutter. For me it’s wildlife photography in its simplest and purit form, it’s how it should be- my choice is not removed by the decision of electronic circuits. What I’m trying to say is that I’m no control freak- but I want to control how my image turns out.

So why the Kowa Telephoto lens? For me it matches who I am and the way I photograph wildlife- here’s why:

The Kowa Telephoto lens has no electronics- it’s manual focus only. That may raise an eyebrow of some photographers out there to question Kowa’s decision to do this- but not me, my choice for wildlife is manual focus all the way. I don’t need to worry about autofocus hunting. If you’ve photographed wildlife yourself, I’m sure you’ve been there, you know, the one with the blurred bird, but a lovely sharp branch. But it’s not just the technical issue and restrictions that autofocus can bring, if it’s manual focus, then it’s my achievement- my creativity and that’s what I find really appealing.

It’s sharp- boy it’s sharp. A Fluorite crystal objective lens delivers the goods on image quality with beautiful contrast and detail.

It’s Flexible. I want compact and portable, not heavy and restrictive. I have the choice of three focal lengths, 350mm/500mm/850mm, the uniquie modular design means I can take the master lens and all three adapters in one kit bag, that’s three prime lenses out in the field at the same time! So one minute I’m photographing Terns flying over my head with the 350mm adapter- the next I’m photographing them on a distant nest with the 850mm one.


It’s tough and reliable. It needs to be, I’m always squeezing into tight spaces, knocking myself and my kit on rocky outcrops or crawling about in dark and damp places and I love it!

The Kowa Telephoto lens has my seal of approval- it may not suit everyone but it suits me and my world. It’s helped me get shots I would have missed with conventional kit and when I’m sitting at home on the computer browsing my images- one thing’s for sure, I created them!
