SteelSeries Kana v2 Review by Takasta - UPDATED White Version - Page 3

post #21 of 846
Great Review rep+
Hopefully this mouse will release in 2 months time.
I had Kana v1. Shape was ok for me but I could not stand the sensor so I had to send it back.
I really cant wait for bst's mouse for another few years.
This is not a good news for Bst tbh. But he couldn't help it.

It's like CS-ProMod and GO. Just get the Kana v2 because the other option is not a reality...

This, try covering the bottom half of the sensor opening with opaque tape. It'll take a few tries to get right but it's better than stacking mouse feet.

Nice review as always.

Oh, my... I must go get it now then!

I think the LOD will be fine when you use it on a red or white mouse pad. This way you retain the performance. Adding tape or stacking mouse feet takes away from performance. I use a red Hien for this reason. I actually don't like the Hien, but for the sake of performance I use it.

I was half joking. Seriously, I think Fifflaren's aim has improved using the mouse, that is if he is still playing the same way.

I thought black mouse pads lowered the LOD. I know a few people on esr are using red mouse pads with their Zowie FK's to increase the mouse LOD.

From my limited testing. Using the standard Avago lens on a red mouse pad lowers LOD. Using the Kingsis lens on a red mouse pad increases LOD.

The following is from my understanding of the information.

The diameter and focal length are different between these two lenses. The Avago lens doesn't magnify whereas the Kingsis lens does. When you magnify the image becomes darker, thus decreasing LOD, response and frame-rates. When you raise or lower the sensor this is doing the same thing as a lens does, meaning it zooms in or out, which increases or decreases resolution/CPI. This is why the CPI is even higher than what Zowie claims, as "their" sensor is lower than suggested, they don't take this into account. Zowie isn't false advertising, they are just (using the word lightly) ignorant about this.

Changing the mouse pad color changes the way light is used by the sensor. The 3090 sensor is designed for 600-700nm, which is orange to red. Most mice use red or infra-red LEDs. You get better response and frame-rates using a mouse pad that reflects this wavelength.


I could go into more detail, but it starts to go into other topics.

If you like black mouse pads for aesthetics at least you know it is for that. It seems like mouse pad manufactures don't understand (or care) that a type of surface and it's color means a lot. To them it's more about having billboards/adverts that gamers place on their table. Most people don't mind that fact.

For instance the Zowie FK's 1150 step has lower malfunction speed than 2300 and the 450 step has lower malfunction speed than 1150. So the FK's 450 step malfunction speed is way lower than the 2300 step.

Delay is increased proportionally via the amount the MCU processes the native setting for its scaled settings. If it cuts one native step in half the delay will be somewhat unnoticeable. If it cuts the step by more than half the delay will be very noticeable depending on how fast/slow the MCU is.

The LOD can be from the typical LED intensity being very high, like the DeathAdder 3.5G, or it can be because the opening for the lens is made for the PixArt sensor. If the opening was smaller the lens would get less light, thereby (potentially) decreasing LOD.


That's not entirely true. Razer and Zowie had a unique setup in that regard.. something I still don't understand.

Typical interpolation of normal data vs sensor size tends to share the same speed limitations of set value. Each resolution increment cutting speed in half as matrix is cut over and over as explained by the Logitech engineer.

That's to say that I don't believe any of these values are interpolated 800+, but who knows ^^ 400 DPI should of course same speed as 800 regardless due to basic coverage.

The rest I agree on wink.gif

What I am thinking is that the Kana v2 is scaling the native steps to achieve the others. Like Logitech does. The way they do it will not be noticeable. When Zowie scales their 450 step they do it from the 1800 step -- this creates that delay -- as the MCU isn't that fast. That's why SteelSeries uses that powerful processor for a mouse. At least that is what I am thinking.

If that is the case, the malfunction speed difference for scaled steps will be negligible when compared to the closes native step. Going from high to low that is.

Alternative values are multiple of 800. It would make no sense to interpolate those values specifically from larger confirmed numbers.

Hence, not likely. They used the same 8 bit freescale unit (pretty fast) on the Kana v1 (single step interpolation upward) and Kinzu v2 (no interpolation).

E: Would be easy to test simply by setting each value and using a program like enotus to notice gradual IPS degradation from each increment upward assuming a typical setup.
