I use Marelux R5 and RF100, and as far as I know, the macro lens length of Marelux and Nauticum macro dome is different. Therefore, will the image quality be affected when marelux macro dome port combined with MFO-3 wet lens? （I have no experience using wet lenses）

As long as you are using the recommended Marelux macro port the MFO-3 wet lens should work the same. I have used wet closeup lenses from several manufactures on both Marelux and Nauticam with like results.

Note that the MFO3 is used with flat ports not dome ports

只要使用推荐的 Marelux 微距镜罩，MFO-3 湿镜应该也能达到同样的效果。我在 Marelux 和 Nauticam 上都用过几个品牌的湿近摄镜，效果都差不多。

Thank you for your reply. I can use it with confidence
