Katzeye or K3 ???

Hello everyone, I wanted to know if it's worth,
to replace my focuscreen K3, with a Katzeye w / optibride.
I wanted to try the Katzeye, hoping it will not obscure my K3, in low light, or closing the diaphragm type f/6-8.
Maybe also improves the measurement spot

Thanks

Hi,

Are you saying that you have a k3 screen, you are experiencing darkening when stop down to f6-8 so you are unable to focus? are you also experiencing metering with the k3?

thanks

Hello and thanks for your interest.
The K3 is wrong only in spots, but recalculation, measured in "center-weighted and spot rimpostando the time.

Sure, I thought the Katzeye is better, and less than obscure K3

1) so called "optibrite" is not being applied to split prism area.

2) katzeye is cut from K3 blanks.

3) K3 has matted (more finer matte than the rest of the screen outside of the microprism collar) prisms (that is what katzeye calls “Plus” - they just cut the screens out of K3 blanks, that's it... K3 already has matted prisms).

so if you want a variety of gridlines and/or "optibrite" outside of the microprism collar - go for katzeye, otherwise K3 is katzeye (or rather katzeye is K3).

Thank you, very kind, explained to me the thing ...

From what I understand K3 and Katzeye, have much in common
and Optibrite, does nothing to lighten the area of microprism.
Said well?

thanks for your kind reply.

so if you want to improve the central spot metering katzeye will not help you over something else also cut from Nikon K3 focusing screen (unless you will suffer a case of placebo over the expensive screen)... however focusingscreen.com has other options available for screens w/o split prism in the center...

Thank you for your kind response.
thought to myself a different model
without microprism on focusingscreen.com hi seen other options w / o split prism in the center

In the end, because I never tried other splitscreen, what changes have the microprism, and not have them??
Without spot metering is more accurate??

Excuse the many questions, but use manual focus lenses a lot, so I need to have the focus, precise, fast, and not obscure easily.

Thank you for your kind response

The graph shows for each type of lens
The model to use splitscreen right??

Gets a bit of effort and read, but is comfortable.

Thanks
