Proper fraction button and Improper fraction button work as pair. When you choose the one the other is switched off.These Pentax have a field of view of 117m at a distance of 1,000 metres (=351 feet at 1,000 yards = 6.7°), which is pretty good, but does possibly fall a little short of what I was really hoping for. Let me explain: The amount of softening of the image on the periphery of the view was extremely minimal and definitely wont bother you. So once again rate these very highly in this department. Optical quality has definitely improved at the lower mid-price level, but neither choice of narrowish FOVs with decent edges or WFs with poor edges is appealing to me. When I spoke to the guys at Pentax about which binoculars I should review for them next, I said that I wanted a quality pair of optics and if possible something that stands out a little from the crowd. That was when they introduced me to the DCF BC 9x32 binoculars. It comes with a whole host of quality features as wall as a fairly unique 9x magnification. Are these the ideal binoculars for those who can't decide between an 8x and 10x magnification? Take a look at my full review of the Pentax 9x32 DCF BC binoculars: These Pentax 9x32 binoculars weigh just 500g (17.6oz), which for a quality mid-sized binocular with objective lenses of around 32mm is very light. For comparison, the excellent Minox 8x33 BL Binoculars weigh 649g (22.9oz) and the top of the range Nikon EDG 8x32 weigh 655g (23.1oz), and the very best Swarovski 8x32 Traveler EL weighs 610g (21.5oz)

The army green hard rubber armour that covers the main housing is nicely contoured and provides a nice grippy surface and should protect the optics from minor bumps and scratches. This covering will also help to dampen down any sounds made from objects striking against the binocular that could frighten away easily spooked birds and other wildlife. It also has another benefit of making the binocular less reflective - bright light reflecting off a metallic object could also easily frighten away wildlife. The body itself is made from tough and lightweight polycarbonate, which is fairly commonly used material in this price range. It is also very important to remember that the size of the objective lens and the amount of light a pair of optics can capture is not the only factor in ensuring how bright the image you see through them is. Image brightness (and quality) is also very dependent on the quality of the optical system and their transmittance levels. Good coatings on the lenses and the prisms can double the amount of light that gets through the binocular, when compared to those that have none or poor quality coatings and as we have already discovered these Pentax binoculars use very good quality glass and coatings and that is why they produce a really good quality and bright image.To try and ensure that my opinions remain as objective as possible, I compared the view through these Pentax DCF BC 9x32 binoculars with that of my control (benchmark) mid sized binoculars (8x32's) that I use to compare with all other mid-sized binoculars that I review.

I can't afford to pay multiples more for roofs that are as good or a bit better, but I can't seem to settle for the two choices cited above at the mid-price level. I never cared for compact roofs due to their small size, extreme light weight, and narrowish FOV, even though 28mm is cutting it close aperture-wise to midsized bins, but even there, the LV's FOV is "compact". As the new BC shows, when you move up to midsized, your horizons widens.

Help and Tips

These Pentax DCF BC 9x32 binoculars are airtight and waterproof to 1m ( JIS-Class 6) which will not only protect them from moisture, but will also prevent any dust and other small debris from entering them that could lead to your view being spoilt. Note: Whilst these silver mirror coatings are excellent and increase the reflectivity compared to most standard binoculars on the market, some optical manufacturers go even further and use dielectric prism coatings that have a reflectivity of more than 99% - but these are usually only found on binoculars at the very top end of the market. Please note : Pentax now produce a newer version of this Pentax DCF 9x32 BC binocular, which I have also reviewed here: Pentax AD 9x32 WP. The air inside of the binocular has also been replaced with dry nitrogen gas during the manufacturing process to prevent internal fogging and thus makes it possible to use the binoculars in places where there are rapid temperature changes, very low temperatures or high humidity levels without the risk of any condensation forming on the inside the binocular. Another benefit of this is that because there is no internal moisture, it also protects the inner workings from corrosion. As well as the phase correction coatings, Pentax also use "silver-evaporated coatings" on the BaK-4 roof prisms. These coatings are added because whilst the roof prism design has many advantages over the porro prism design, it does have one major problem in that one surface of the prism does not have total internal reflection. Therefore to get the best optical performance it is very important for to raise the reflectivity of this surface and to do this, a mirror coating is used on those surfaces.

I felt that the overall balance of these Pentax DCF binoculars was excellent and this is where the thumb indents that encourage you to get your hands into exactly the right position help. Whilst the balance on smaller, lighter binoculars like these might not be quite as important or even noticeable as on larger optics, it is still something that should be taken into consideration. A badly balanced binocular will be far less comfortable to use, especially over longer periods of observation. A well balanced binocular like this is also far easier to keep still, which helps you to maintain a steady, shake free view.Ideal Uses: Like most mid-sized binoculars these are ideal travel binoculars, perfect to take on a camping trip. Their size and 9x magnification means they also make excellent safari binoculars, especially if you like to observe birds as well as the larger land fauna that Africa is most famous for. As such, I would also say that these Pentax binoculars would be great for general wildlife observation and even some types of hunting where size and weight are important. Like most mid-sized binoculars these make a good all-round general use binocular. Strong Points: What really impressed me with these Pentax binoculars was just how light they are, yet they body still feels tough enough to handle most normal uses. The open bridge design not only looks good, but makes them comfortable to use when glassing and really secure to carry about even in one hand. Their twist up eyecups with a generous 16mm of eye-relief and 5 fixed stops are some of the best that I have ever used. Overall, I thought that the quality of the view through them was very good and easily matches a lot of binoculars that cost much more than these. Polynomials with rational coefficients always have as many roots, in the complex plane, as their degree; however, these roots are often not rational numbers. In such cases, the polynomial will not factor into linear polynomials.
