Heliopan closeup lenses: These thread into the front of a lens like a filter and increase magnification. They are brass & constructed with Schott glass. They are labeled +1, +2, & +3.

These thread into the front of a lens like a filter and increase magnification. They are brass & constructed with Schott glass. They are labeled +1, +2, & +3. Does anyone know how much they increase magnification?

Thanks

You might need to do some research in that to have an accurate answer as this deals with optics and formulas that depends on the lens it is attached to. Generics explanation is 1 (lens) + 25% per diopter so a 1x is 1.25, a 25% increase, 2x = 1.50, 3x = 1.75 ...

Note that any glass placed in front of a lens creates diffraction as well as distortion and are best used at their center. If you stack them you will run into more trouble.

That said, they are great for casual users.

Thanks. I forgot about Johann Ingles-Le Nobel and his website

I havevhim bookmarked and he included a calculator.

Exactly what I needed.

I also sent an email to Heliopan in Germany.

Thanks. I’m aware of their short comings. Heliopan uses Schott glass which is about the best available. I have a Nikon 6T.

I did find a helpful calculator.

The numbers are Diopters. But Heliopan does make close-up filters? Cool perhaps. Might not be bad. What do they cost? Certainly more than the $25 Hoya set. Though would I really need these as I do own four actual Macro lenses? (35mm, 50mm, 50mm (different mount), 100mm).

I do not think anyone is proposing that your purchase more stuff. You seem to have it all already....

Mike: Yes they do make them. The cost varies, depending on the size, ranging from $45.00 each to more than $100.00. Most sizes have diopters from 1-4. What I wasn’t sure of is if the numbers were standardized. Turns out, they are. Since you have 4 macro lenses you don’t really need them. I’ll explain my situation.
I do a lot of macro. Beginning a year and a half ago, due to a health issue, I needed to go light or quit photography. I chose to go to mirrorless with a limited macro option, the best of which was limited to 2:1. Since I had a Nikon 6T closeup lens from my film days, I looked into stepup rings discovering that I would need to stack two to go from 39mm to 62mm: 39mm-58mm and 58mm-62mm. Rather than do that, I decided to look into buying a 39mm. The cost is similar between two brass stepup rings and the 39mm closeup filters. Since Heliopan uses Schott glass & brass, they were my choice over other manufacturers. Brass is superior to aluminum for fine threads. (Machinist in a former life).

I use the step up ring approach for the DCR 250.. I searched and found the correct singular ring that made 3 or 4 steps in one ring. If you still have the DCR150 it comes with a clip on type of attachment or you can use the rings as well. Extremely sharp close up lens..

One other point to consider in utilizing macro supplemental lenses: simple ( one piece of glass), achromatic duplex( two pieces of glass). the Nikon 6T adapter mentioned by LoneRanger (above) is an excellent close up adapter and is duplex. I tried another similar magnification adapter from some other maker, and the images were not nearly as good. Find out from Heliopan if its closeup adapters are simple or duplex. It DOES make a big difference.

Thanks. I have the same Raynox that you have. I’ll try that approach first.

Canon makes 500D ( +2) and 250D (+4) duplex close ups in 52 and 58mm and there are others - like Marumi.

IMO, you will get better optical performance by using a LARGER diameter diopter lens so you only use more of the central portion. But, I do agree - closer to the prime lens is better also.

Its all in the numbers (+1,+2, etc.)!

Thanks that is a good point
