IS FIELDSCOPES
IS 50, IS 60, IS 70
Discontinued Jan 2008. Full range of accessories available.
IS series fieldscopes are designed to provide high levels of performance & versatility in compact & lightweight bodies. Available in three objective sizes; 50mm, 60mm and 70mm with the option of straight-through and 45° angled viewing, these modern interchangeable eyepiece fieldscopes are produced using lightweight compound materials and all six models feature high performance 4 element fully multi-coated objective lenses, BK7 fully multicoated prisms and internal focusing.
Model: IS 50 / 45
IS 50 T-Scope
At just 20cm long and weighing 528g, the IS50 re-defines the 'compact telescope'. Designed and engineered to be both a competent fieldscope in its own right as well as a brilliant travelscope for the space conscious birdwatcher, shooter or archer, the quality of both optical and mechanical components ensures the IS50 will outperform many of today's current crop of 60mm spottingscopes of similar price. Compatibility with HR*, HDF* and SDL* eyepieces means the IS50 can also be purchased as a 'body only' for existing Opticron fieldscope users.
Model: IS 50
Model: IS 60 / 45 
IS 60 F-Scope
Specifically designed to offer improved levels of optical resolution compared to preceding Opticron models in a more compact & lighter chassis, the IS 60 is a highly competent spottingscope that is both easy to use and transport either on a lightweight tripod or bipod. Matched to one of the three dedicated IS long eyerelief eyepieces, (40916S 25xWA, 40918S 18-54x and new 40919S IS Pro 15-45x), the model is an excellent choice for the first-time birdwatcher as well as the 100m plus shooter or archer looking for accuracy at 30x magnification and over.

Model: IS 70 / 45 
IS 70 F-Scope
Available from Autumn 2005 this Japanese designed IS 70 weighs in at just under 950g and offers remarkable performance for its sub £200 price tag.
Featuring an f.400mm, 4 element objective with a surface area 35% greater than the IS 60, both straight-through and 45° angled viewing models deliver remarkably bright and sharp images with good colour contrast across a wide range of magnifications.
The IS 70 will take any of the IS, HR or HDF eyepieces currently available and even accepts the 40935 SDL as an 18-54x.
Model: IS 70
Other features and options include;
- 180° rotating tripod sleeve for use with standard photo/video tripods and bipods with ¼" thread connection
- Retractable lens hood to protect against glare

EYEPIECES
A wide range of eyepieces are available for use with IS Fieldscopes. Choosing the best eyepiece is often confusing but making the right choice will depend on price and application. It is important to remember that the eyepiece is an integral part of the whole set-up and opting for a lower quality lens will make a difference to the overall image quality derived from the fieldscope.
IS EYEPIECES CLICK FOR IMAGES
Dedicated long eyerelief eyepieces and best overall choice as a first eyepiece. If you want a zoom eyepiece and 'high' top end magnification not essential, choose 40919S over 40918S due to higher resolution afforded by this more expensive eyepiece. Eyepieces screw directly onto telescope bodies. Eyepieces in table marked * have a twist-type eyecup.

HR EYEPIECES CLICK FOR IMAGES
Good choice as either supplementary eyepiece in combination with IS. All HR eyepieces are long eyerelief and 40933S HR2 is quite a bit sharper than 40918S IS eyepiece. Eyepieces in table marked * have a twist-type eyecup.
Note. Eyepiece adapters are required to fit HR eyepiece to IS bodies. These are supplied 'Free of Charge' if purchased with a new scope body or priced at £3.00 inc. VAT if purchased separately. Use 40925S adapter to fit 40812S, 40930S, 40931S and 40932S HR internal screw thread eyepieces. Use 40928S adapter to fit 40933S HR zoom collar thread eyepiece.

SDL EYEPIECE CLICK FOR IMAGE
An F24 - F8, 5-group 8-element 'super' zoom, the 40935 SDL has been designed to maximise the performance gains inherent in Opticron ED objective lens fieldscopes at higher magnifications. Offering an optimum ratio between field of view and resolution, the main viewing characteristics of the SDL eyepiece are superior cross-field definition at all magnifications coupled with exceptional viewing comfort. Mechanically the eyepiece is waterproof, uses the M41.5 collar thread attachment, features a 90° rotation between high and low magnification settings plus a rotating eyecup that can be positioned to match individual needs. Supplied in soft padded case.
