Characteristics of the 6 recommended KASE filters:

1 super hard film， lens surface hardness up to 3HB to 1 times higher than that of other lens hardness up to 2N， can resist the impact force， protect the lens more effective damage.

2 filters using multilayer coating of up to 18 layer， super coating alcoholwipe not to go.

3.UV transmission rate up to 97%， the light transmittance of MCUV up to 99%.

4 whether it is UV or MCUV， are using the thickness of only 5.4MM slimframe， lens has not at maximum wide angle dark corner， can reduce the overall weight of the equipment， simultaneously is convenient for installingthe lens cap.

5.KASE full range of products with the German Schott optical glass as material， ensure the optical properties of lens quality.

The 6 lens edge by edge grinding technology， can completely prevent theedge reflection.

We all know that the diamond is very hard， but the rigidity of diamond isreached number， slightly clear who will tell you that it was 10HD

KASE filter after tempering hardness is how much， we are very sorry to tell you， a little lower than the diamond to 8HD

. (a HD force， equivalent to a pen with a KG draw strength and lens two hundred times without damage or wear flowers)

But we ordinary glass hardness of only 4HD， that is to say other than lens hardness up to twice the.

Glass material for the B270 white glass， the material quality is good

Lens thickness is 1.0MM-1.1MM， the lens light， suitable for wide-angle lens，no dark corners

Lens use double-sided multi-layer coating process， both sides is 18 layers of coating.

(and double in the coating before the mirror polishing， the emergence of small spots of reduced to the minimum)， so the lens transmittance reached 99% above the average

A metal ring material hardness and better than the original， the metal ringthickness， lighter weight than the old one， the focus of the lens by the motorspeed is faster and more sensitive

EVA lining internal fixation increased diagonal pickup groove， reduce mirror surface contact
