Diopters

HI,

does any one use diopters on 60mm/ 105mm macro lens, if so what type & size

Any comments well come.

I have a set of Hoya +1, +2, +4 diopters that I use on my 105mm VR occasionally for super macro (getting better than 1:1 magnification). These are internal dry diopters, so the drawback is that once you have them on, they stay on for the dive. It gets a bit trickier to frame and focus with a diopter on (I mostly use the +2). I think they are 62mm filter size (whatever the 105mm VR is). The alternative is a wet diopter which can be removed during the dive, but they may be considerably more expensive and may not necessarily be available for the particular port you have.

Nikon 3T, 4T (105mm old version)...

Nikon 5T, 6T (105 VR vesion or new 60mm)

Canon 500D (Sigma 150mm)

Those are dual element diopters. Those are the one you´ll need.

Though I think only the T3 is still being made out of the Nikon diopters, correct me if I'm wrong someone.

Canon also makes the 250D, the 52mm versions of the Canon diopters should work on the old 105.

I am very happy with wet diopters. you can take them off during the dive and so you get way more flexibility.

i have used the INON skrew on diopter and the Macromate.

you see a big difference, as the Macromate is made of different glass elements (like the ones mentioned above) and so produces a better image quality.

So if you go for a wet diopter, then choose a acromat (more elements) diopter like the macromate or the seacam ones (as you have a seacam housing).

The Inon diopter is a true wet-contact achromat. The Macromate is not.

I dont believe that Nikon is making any of their two element diopters anymore- I have the 3T and 4T but really only use the 3T on my older 105mm lens due to liking the working distances a bit better. I only put on the 4T if I know an exact subject is down there and the extra magnification is needed.

I am quite happy with the external Nexus diopter (Woody's diopter) in 100mm macros. Easy to carry, easy to skip on and off. Also have the Canon 500D, but found that it doesnt fit inside of any of my ports, and even if it did I probably would seldom use it, because I change my mind so many times during a dive and want to be able to shoot critters of different sizes, so an external diopter is perfect for that. Another plus with the Woody is that it is very reasonably priced too.

Anyone know the Marumi Achromat diopters?

In some places they says that the quality is better then Nikon 6T and this company is an OEM for Nikon & Canon.

@ craig:

are you sure about the macromate not being achromat? i actually thought it was ... otherwise why would it be so expensive?

serge

The Macromate uses a dry achromat sandwiched between two flat ports that introduce chromatic aberrations of their own, so to say that the Macromate is chromatically corrected doesn't tell the whole story. The Inon doesn't suffer from those issues since it is designed to be submerged directly. While both most likely qualify as "achromat", I wouldn't assume that the Macromate offers less chromatic distortion than the Inon. At very minimum, fewer optical interfaces means that the Inon may preserve more contrast. They have very similar apertures.

It's possible that one outperforms the other regardless of "theory" and I've used both but never side by side. I like the Inon because it's less bulky and far less heavy underwater. My Macromate scratched too easily although they've fixed that since. The slip on design is bulky and hard to store. The flip design is much better but interferes with my modeling light. Like so many things, I believe the perfect wet diopter doesn't exist (yet). I think the Inon is the right design but it needs an increased aperture and we need macro ports to accept them universally.

Though I think only the T3 is still being made out of the Nikon diopters, correct me if I'm wrong someone.

 

Canon also makes the 250D, the 52mm versions of the Canon diopters should work on the old 105.

You have to get nikon dual diopters on ebay. Nikon discontinued this products.

I have Woody´s diopter which is good quality also.

HI All,

many thanks for all your advice. So if i was to get a wet diopter it would work with both the 60mm &105mm

as it would fit over the flat port & the only difference is the extender for the 105 lens.

Though a couple of things I have read suggest that the nexus wet diopter is as much use as a chocolate spanner on the 60mm.

Any comments ??

I can't answer for the Nexus wet diopter, but that is definitely true for the Macromate. The working distance of the 60mm is already so short that shortening it anymore would be just about impossible to adequately light your subject. And that is assuming that your subject would allow you to approach so close.

Cheers,

Mike

Thanks Mike - that is pretty much what I had read re the Nexus also.

Sorry for the hijack Andy...

Hey big Paulie,

I would have to check my results, but I'm pretty sure that the Nexus diopters add a small amount of magnification when used at a set distance.

I'm aware that most people use the diopters to shorten the working distances of the larger telephoto lenses. I conducted my own tests to try and work all this stuff out when I had it all explained to me and was still dumb enough to not understand. . . . hehehe.

Anyway, when I tried the 'wet' Nexus on my 60mm micro, it showed a small increase in magnification at the origional distance before I tested for the new close-focus.

I was testing the 60mm micro because I use it with a Kenko 1.4 teleconverter. I find that it gives me really good results and is a LOT more user friendly than the older 105mm micro; auto focus, especially, is a lot quicker and lacks all the 'hunting' that is associated with the older 105mm micro...

Now, whether this small amount of increased magnification is of any use to anyone, only the end user can decide after trying for himself/herself...

HTH,

Bruce...
