M4 & IDAS HEUIB-II/NB1 Filters

This was another shot two weeks ago.

BORG 107FL F7.8 + IDAS HEUIBII-52 + ASI2600MC

ASI2600MC has the built-in UV/IR filter. So An extra UV/IR filter is not necessary. But reasons why I still like to use HEUIBII is illustrated below.

Be aware scales don’t match.
  • HEUIBII’s UV and IR cut-off lines are narrower. In general, possibly sharper image result in the refracting optics.
  • HEUIBII looks cleaner cut-off shape at the bottom.

So HEUIBII is my default filter as UV/IR even for ASI cameras. For modified 6D, it is the must-have item.

HEUIBII and NB1 haven’t been available long time. But finally they are now in stock.

We resumed shipping both of them from yesterday. So they should be in stock at your local or favorite shops shortly. To the customers who have been long waiting, thanks for your patience.
