Anybody tried the 60mm lens set to 1:1?

[Ardy]

I often wondered what the 1:1 switch did and having just read up on it, maybe it has a use. The problem is that if you use AF the 1:1 automatically switches off. So you have to use manual Focus.
Having just got back from Bali I realise I am not getting full 1:1 out of many of my shots. In some instances that's a good thing but when you are seeing subjects below 3/4" or 20mm which covers most of what I photograph in Tulamben then setting and leaving it on 1:1 might have some advantage.

Anyone here used the lens like this? If yes what advantages/negatives.

I have always had issues deciding if the lens is at 1:1 or not.

Can't you assign one of the buttons to force the 60 to 1:1? Nominally the 1:1 setting is for MF use, set it then use your fins to get to the right distance.

Thanks Bill, I didn't know that option was available. Will look into it, If I can then that's a good solution. I generally use BBF so moving to stay in focus is something I am used to.

I dont think so. It’s a physical switch that reverts after an exposure, and the MF is manual-only. There’s a gear for the MF, but not for the 1:1 toggle. FWIW, the Nauticam port for the 90 includes the range-limit and 2:1 switch, and a manual-focus gear is available.

I did some testing with my 60mm yesterday just around the property and I was surprised. With the lens set to 0.19 ~inf I had trouble getting the lens into 1:1 but it easily went to 1:2. When I changed the setting to 0.19~0.4m I had a much easier time getting to one to one.
I suggest based on this I will only use my lens on 0.19~0.4 as opposed to the stnd position which I normally set the lens to.
I have owned this lens since 2015 and should have done this test years ago...

The only problem with that is if you see something interesting further than .4m away. I wish there was a way to toggle that while underwater; but because I *might* see something I want to take a picture of further than .4m, I always stay in the .19-inf as well...

luckily I have rarely used the 60 for anything apart from macro so I will go with the restricted focus and see how it goes. The number of shots I have taken with the 60 that are not at 1:1 when they should have been is more of an issue for me than the occasional fish shot. I didn't realise how difficult it is to get the 60 to 1:1 on 0.19-inf position.

What is the problem you are trying to fix doing it this way again please?

I found that many of my shots are not 1:1 and I am cropping images. As I said in the entry I struggled to get the lens to 1:1 in an out of the water test set on 0.19-inf.

It also focuses more quickly if set on the more restricted range.
