Best for
A vintage Kowa + Opticron combination - the TSN-1 was a respected Kowa scope body in its era (pre-2000s), and the Opticron HDF zoom eyepiece adds modern zoom capability. Used scopes like this can be surprisingly good value - heritage optical quality at a fraction of alpha-brand new prices. Best for casual birding rather than serious competitive use.
Frequently asked questions
Is the TSN-1 still a good scope today?
For casual use, yes - image quality remains acceptable. For serious competitive birding or digiscoping, modern scopes (Kowa TSN-770/880, Swarovski ATX, Zeiss Harpia) offer significantly better optical performance. Think of this as a characterful heritage option rather than a current working tool.
Why buy from Bass & Bligh
Bought from a real shop, not a warehouse.
Dispatched on the Monday… great service
Ordered a Panasonic four thirds lens dispatched on the Monday after purchase and delivered on the following Tuesday great service. Tried on the camera and initial thoughts are wow pin sharp and clear photos. Thank you
George P.Ordered a lens onlineA proper little treasure trove
3rd time I've been to this shop to treat myself to some new kit. Always very friendly and knowledgeable. Fairly priced too. I would highly recommend a visit if your nearby and looking for camera gear. I'd say if they don't have what your looking for, it's probably not possible to find anywhere. It's a proper little treasure trove.
Philip B.Third visit to the shopBrilliant advice with awesome customer service
Sure you can buy online and possibly save a few pounds.. but if you require and appreciate knowledge and brilliant advice with awesome customer service then it's a no brainer...This is a real camera shop like it used to be back int day..
