Wildflower photography has been a long time hobby. For detailed close ups I've used macro lenses such as a vintage 1972 Micro Nikkor 55mm f3.5 and a 1986 Minolta Maxxum 100mm f2.8, mounted on Sony bodies (a7iii, a7Riii, a6500). Both these lenses have remarkable resolution and serve for this purpose, but neither is a lens I'd use as a walk around. So I have a Zeiss Batis 40mm CF. But I really enjoy using my Zeiss Loxia lenses, yet they do not focus closely. So the Marumi Achromat 5x was a want, not a need, to derive more use from my two Loxias.

Using the 42mp Sony A7Riii I've compared resolution of the Marumi Achromat 5x on a Zeiss Loxia 35mm with what I can obtain using the vintage Micro Nikkor. Both are excellent, with the Loxia+Marumi at least as clear as the Micro Nikkor, and maybe better. The Micro Nikkor imparts a blue tint from ancient primitive coatings. I prefer the results with the Loxia+Marumi combination. Photo of budding rose was made with the Loxia 35 + Marumi Achromat 5x at f/8, ISO 100 1/320" and is a focus stack assemble in Helicon Focus. There is no lack of resolution!

Also I've had fine results using the Marumi on a Loxia 21mm for a wider view with one flower as the subject; this is a good combination, however for this type of composition I'd prefer my Laowa 15mm Zero-D. But, I might not have the Laowa with me.

I also experimented with the Marumi on my Micro Nikkor 55mm. This lens only enlarges to 1:2 reproduction. Though I have a set of extension tubes their use imposes a loss of effective illumination and exposes the sensor to airborne contaminants when installing in the field. With the Marumi added to the Micro Nikkor reproduction goes a bit beyond 1:1 and illumination is not reduced. The second photo shows tiny, mm-sized, hairy bittercress growing between flagstones (also a focus stack) with the Marumi on the Micro Nikkor. Size is shown in the single f/16 frame including my thumb. Set up is shown in 4th frame, where flowers are too small to be seen!

Finally I've also used the Loxia 35 + Marumi on my a6500 producing a full frame equivalent field of view of 52.5mm. It's a fine alternative to the Micro Nikkor on a FF body, sharp with good color, and unlike the Micro Nikkor, weather sealed.

For a lens hood I'm using 52mm screw on hoods. Hood shown in frame 4 is a Nikon hood. Unless adding a CPL, I no longer stack filters with the Marumi. Recently I got the Marumi jammed in the threads of the brass B+W UV filter already on the lens. Believe that when adding the hood too much torque was transmitted. To separate the filters I cooled them in the freezer, then gently tapped around the circumference of the filter frame using the handle of a table knife. They then separated easily.

At some point I may buy a 77mm Marumi Achromat to use on my Sony 4/24-105 G. Would be an interesting combination, more useful than the 1986 100mm Minolta macro, but costly, as much as I had paid for the used Minolta!

I use the Marumi close-up lens with my Sony A6000 and Sony 18-135mm, and it works great! Previously the closest I could focus was about 12 - 14 inches at the 135mm setting (200mm in 35mm terms). Now with the Marumi close-up lens I can focus about 7 - 8 inches. I calculated that I should be able to get close to 1:1 magnification. I cannot detect any chromatic aberrations, and the images are sharp. Only drawback to this very high magnification is that the DOF is thin, so it is better to mount the camera on a tripod, and use focus stacking software if you need more DOF. I would definitely recommend this lens if you need lightweight, high magnification.

Cranked it on a Fuji GF 200mm F4 close up lens to achieve more Macro magnification. Extremely righteous portrayal of a budding weed. I'm collecting +3 +5 magnifiers in 52, 62, 72, and 77mm threads for a complete set. If you go the auxiliary lens route you'd appreciate having both +3 and +5 as they'll manage foreground and background to subject perspective and out of focus framing better. At really close focus it's tricky to frame subjects surrounding details as tiny camera movement results in huge wallop on the sensor - film plane. The Marumi achromat lens does not interfere with the host lens resolution or contrast so what you put it on only allows vastly closer focus. Cheap trick with a big kick.

Five-star product optically. However I am disappointed that the pouch is now hard-plastic, rather than the felt-padded leather as in the last time I bought this product and is still shown in the picture. Sometimes I wish manufacturers would just embrace inflation and increase their product price by 2% every year, instead of slowly eroding the user experience via cost-cutting.

Used with a Sony RX10 IV. As another reviewer pointed out, this one fuzzed out the image with strong halos at all focal lengths from 100-600mm (35mm eq). Auto-focus simply would not work. Not a good combination. The unit might work with a different camera. I eventually ordered a different brand that offered a +3 achromat, and found that one workable. +5 may be too much for the RX10.

After using this lens a bit I thought I'd change my review. First of all the quality is surprisingly good. You can buy them in the size to fit your lens or buy a bigger size and use them with a step-up ring so they will work with several different lenses. The only disadvantage of buying a bigger size is that they are a bit heavy and the bigger the size the heavier they are. In my opinion they work best with a zoom as a zoom enables you to change the magnification as you zoom in and out. The +5 works best with a zoom in the 50-200mm range and the +3 works better in the 200 - 300mm range. The +5 is too strong as you get near 300mm and the +3 is too weak as you approach 100mm or less. If you get one too strong you can't focus because the magnification is too high and if it is too weak you may as well crop a photo a little rather than buy this lens. Once the lens is attached then the focusing range is reduced so you would have to remove it to focus outside it's range. With a true macro lens you can focus close or as far away as you please. Other than these limitations they are capable of taking very nice closeups. They are easier to use than adding extension tubes. Unlike extension tubes adding one of these lenses doesn't change the aperture but you often have to stop down a bit anyway to get all of your subject in focus. Since good macro lenses such as the Tamron 90mm macro F2.8 runs between $400 and $500 it is worth trying one of these lenses. Don't buy the cheap single element ones as the quality is terrible. These are dual element achromats.

First let's get the positives out of the way.
1. The build quality of this lens is good and it's a weighty item giving the impression of quality.
2. The lens allowed focus closer than normal and I obtained 1:1 magnification on a Sony RX10 III.

Unfortunately the good news ends there.
1. Focus is difficult to obtain manually as the distance guides on the camera are no long applicable so focus is achieved by gently moving backwards or forwards until focus is achieved. This is trial and error to begin with as you don't know how close to get to the subject. Once I had learned that focus could ONLY be obtained at roughly 12-15cm from the end of the lens I knew to rock backwards and forwards around this distance. This is VERY difficult without a tripod. When things move in the breeze (flowers) it is even more difficult. I wasn't able to obtain a single keeper from my short trial with the lens.
2. Autofocus does not work at all. Manual focus only which is expected for macro really.
3. The only option with the lens was 1:1 magnification. There is no option to move further away to lower the magnfication and allow further depth of field. Just one magnification and distance option and that's a few inches from the subject.
4. There was significant corner softness/blurring. Just the centre was in sharp focus.

In summary the lens does as advertised, but in a manner that is not really useable in the real world. Sadly I have returned. I have read other glowing reviews of this lens and seen some excellent YouTube footage so I can only assume that the lens behaves differently depending on the camera/lens it is attached to. If you have a Sony RX10 mk III I cant recommend this lens.

photos are from my first attempt using this "filter" in the garden, handheld, for the price I cant really fault it, some shots may have a little aberration, but when using the lens at 300mm the depth of field is pretty short even with small aperture, so it is hard to tell. I recommend it as a first step into macro photography, especially if (like me) you cant afford a dedicated macro lens. Photos taken on a Nikon D3400 with a Nikkor 70-300 AF-P f/4.5-6.3G ED VR lens + the DHG330

I'm using with one of the best Pentax lenses ever made - a 50-135 DA*, I also had a real macro lens to compare it to,I found that the shots with the Marumi were just as good and many actually better. With the Marumi I seem to get more light/faster shutter speed than the dedicated macro (not suprising when you look at the size of the front element).

In terms of depth of field I lost nearly 2 stops, so even with an f2.8 host lens do not go below f6.3, the results will be dire - get plenty of light (a flash or a very bright day) and go for high aperture at all times, bump up the ISO if necessary but keep that aperture value high.

If you have a poor host lens don't expect miracles, also expect the minimum focus distance to be halved (great news for me as the DA* lens has a 100cm min focus distance normally).

First the lens is arrived without the fine leather protective case shown in the photos. instead a plastic box!Now come on! (other wise 5 stars)
That's out of the way now the lens!
When I ordered this filter, I was not sure what to expect. After taking a number of pictures and getting use to the focal length I am absolutely happy with it. Its sharpness, contrast, and colour are verygood. If you enjoy close-up photography but do not want to buy a macro lens, I highly recommend this filter. It is way better than most non-achromat filters on the market as it combines two elements to correct chromatic aberration.
I use it with a Sony a5000 and a6000 SEL55210 you can see samples here

Lens seems fine and as expected. The only criticism I have is that for the price it would have been nice if Marumi had supplied a decent case like the ones that Canon supply with their close up lenses. The thin plastic one that it comes in is not a good fit, nor does it protect the lens. I’ve had to buy an extra case so I’m reducing the rating to 4 stars

This replaces Raynox DCR 250 - returned due to vignetting on my Sony RX10. The Marumi is excellent quality and being the same diameter as the RX10 (62mm) only starts to vignette from 50mm - a workable FL for my type of photography.

It is 3 diopter so is suitable for flowers but not so much for small insects (for this one would need the next size up 200/5). There is very little chromatic aberration due to it being achromatic.

Recommended for getting into macro and occasional use. I carry it when travelling saving 'humping' the more weighty dedicated macro lens.

Just wonderful on my little Canon S120 (had to to build a tube for it). Good optics, and good glass. The photo is from the S120, a 12MP camera.

Well made lens but not suitable for my needs as can only be used at widest angle of camera zoom lens which meant had to be only a couple of cms from subject to produce image larger than possible with camera lens only. So returned.

Good results rivalling Raynox and similar others. Though for the price I would have expected a case better than the flimsy box supplied.

I have the +3 and was so impressed with that I went for the +5 and I’m not disappointed. I mainly use on my Sigma DP3M and I am thoroughly impressed with image quality, particularly that the sharpness is maintained with such a simple attachment. Would recommend.

Very pleasant results, good thing if u wonna try macro without buying more expensive lenses just for it.

Great product - you only get a fairly short range of acceptable focus, but the quality is excellent and the results are also excellent.

Having used the +3 version for a year I decided I needed the more powerful +5 and the cheapest source was via Amazon. The lens adds extra magnification to my very best macro lenses without degrading the image. Images may be found under my name, as author, here:


item is exactly what's described.
note that with my Sony rx10m3 the working distance is ~30 cm and requires a tripod for sharp pictures

Really is as sharp as other reviewers claim. I use it in combination with a D800 and 70–200 f4 VR lens and really cannot see a loss of quality. Overall, this is a much more successful combo than the D800 and my trusty but aged 105D macro.
