Kowa Sporting Optics

Welcome to the REAL world

Kowa unveils  new micro four thirds lenses at The Photography Show 2014 in Birmingham. 

With over 60 years of technical experience and know-how in optics, Kowa is proud to present the next generation of crystal clear, super wide, fixed focal length lenses.


The super wide angle 8.5mm lens offers a wide field of view unmatched amongst other lenses conforming to the micro four thirds

system standard, while minimizing distortion to a value of only 0.12% even though it offers a diagonal angle of view of 106 degrees.

The model with a wide angle view and a 12mm focal length (KOWA PROMINAR 12mm F1.8 MFT) has a bright F1.8 aperture, and its distortion value has also been reduced to 0.59%.

The model with a 25mm standard focal length (KOWA PROMINAR 25mm F1.8 MFT) is suited for use in a variety of shooting environments, it has a bright F1.8 aperture and provides a very sharp image.


Please see below the www.photowalkthrough.com interviewing Kowa at The Photography Show regarding these new lenses:

These lenses maintain the optical characteristics adequately, supporting the high resolution 4K and 2K cameras.

Get closer to the action with our range of high quality and easy to use Kowa digiscoping adapters.

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. Kowa have digiscoping adapters for use with DSLRs, compact cameras, video cameras and now even iPhone 4/4S.

D-SLR digiscoping


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. The TSN PZ has a variable focal length range of 680mm-1000mm, which gives you the added flexibility when composing your image.

Alternatively, you can use the TSN-PA7 adapter. 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.

Compact Camera digiscoping


Unleash the telephoto power of your Kowa spotting scope by adding the TSN-DA4 compact camera digiscoping adapter. The TSN DA4 attaches securely yo your Kowa spotting scope eyepiece by simply unscrewing the eye-relief cap, allowing you to attach either the TSN-DA10 collar (TSN 880/770 series), or the TSN-DA1A collar (TSN 660/600/82SV). The DA4 slides over the collar and is fixed by tightening the screw to lock it in place.



Transform your iPhone 4/4s/5 or Galaxy4S into a super telephoto lens.

It couldn’t be easier to start taking magnified images or HD video with your iPhone/Galaxy4S and Kowa optic, via the TSN-IP4/TSN-IP5/TSN-GA4S digiscoping holder. Simply slot your iPhone/Galaxy4S into the holder and screw in the appropriate adapter ring- then push the adapter over the eyepiece of your spotting scope and you’re ready to digiscope.

My first post – about one of our customers…

Having been given this opportunity to blog for Kowa, I thought my first post should be about one of our customers. I was recently contacted by a very nice young woman named Annette, she is a birder who is experienced in digiscoping in addition to her photography. She had spoken to my good friend Kevin Bolton and he suggested Phonescoping.


She contacted me for help and advice, I spent a couple of evening’s on the internet talking her through what to do and tip’s to get the best out of her Kowa iphone Adapter and Kowa Telecamera App, she sent me her first pic’s and I have to say they have come out very well, in her words, she explains her story -

I recently purchased an iPhone 4S and downloaded the Kowa Telecamera iPhone camera app. My good friend Kevin Bolton offered me the Kowa adapter for my scope and Paul Hackett gave me a tutorial using the app along with quality advice. I recently photographed this Chipping Sparrow in my back yard. I found it very helpful and relaxing to practice on this particular bird. It was very patient which allowed me to take my time with the scope and settings on the app.  

At times it has been difficult taking photos of active species – sometimes rushing the shots, causing incorrect exposure settings and blurry images.

Paul and Kevin have been extremely helpful to me during my learning curve with the iPhone digiscoping.

A couple of my favorite features the app provides is the use of the iPhone headphones, the volume control allows you to take pictures by pressing in
between the plus and minus which has proved to be very helpful, no need to touch the screen and no shake, and also the ability to tap the screen twice to magnify the image and tweak the focusing on the scope so it is as sharp as can be.

I emailed my photos to Paul and he was very pleased. I am very impressed with the amazing quality of the Kowa app and the iPhone Adapter combined.”
