Great attachment at 22mm+
On a R100 it works great at 22mm+, although if you zoom out you’ll see a vignette. The vignette can look great as a stylistic approach! Great value for the price!

Well Built, Quality Packaging, Widened Field of View. Lens Corners Visible during Low Zoom.
Hello there! I am fairly new to photography and just recently purchased my first “real” camera (Not a smartphone and over $100 😂).This review Is for the 49mm Macro/Super Macro Lens, mounted and used on a Canon EOS R50 with RF S18-45mm f4.5-6.3 IS STM.I decided to purchase this product while searching for various lenses for my camera. Since I am new to the photography game, I wanted to try out and add various lenses to my kit. Being that the price point for this lens was far lower than other lenses and seemed to have decent reviews, I figured I would give it a try.The product arrived quickly with Prime and I was extremely excited to test it out. It was packaged nicely and professionally; (outer product box, inner, more protective inner box, leather type (not sure if actual leather) pouch with draw strings, and lastly a disposable plastic bag.Unfortunately, that is when I experienced my issue. The lens would not fit onto my preexisting 49mm thread, 18-45mm lens. Being as this is my first lens purchase for the camera, I was both concerned and slightly discouraged. I looked at my order history and realized this product did not state anything regarding the compatibility with the EOS R series cameras, but rather the EOS M series. I researched online thoroughly and concluded that regardless of if my camera is an R or M series or if the lens is an EF or RF, 49mm should still should be compatible.I then looked through my recent orders and Amazon and found the product description, verified I ordered the correct lens thread size (49mm) in which case I did.From there I grabbed a ruler and took a measurement of the thread size of the mounting portion of the lens, I found the size to be 55mm rather than 49mm. Although I ordered the 49mm, I received the 55mm, even in a 49mm box.I started the replacement process on Amazon, chose to “Replace with the same item” in hopes that it was just a discrepancy when the product was boxed. I received the new lens a few days later and could immediately see the difference in the mounting thread sizes.It mounted right up to my existing 49mm lens with no issues.As for using the lens, it does have a bit of weight to it, I’m sure probably not as much as other lenses, which I have not had the opportunity to test, so I cannot definitively say it is heavy or light in comparison.It definitely does seem to give a wider field of view which will be great for various types of photos. Both auto and manual focus still seem to work without any issues. Clear view, no issues so far with ISO or high shutter speeds. However, there are two issues I have noticed so far with the lens;1: When utilizing the cameras integrated flash, the size and length of the lens definitely casts a shadow at the bottom of the shots. An external flash would probably correct this depending on how high the flash sits.2: The corners of the lens show on the image unless I zoom to right around 22mm. Although this could be a deal breaker for some, I actually like the effect it gives the image. This also will most likely be dependent on the lens type/focal length used.One more thing to note although it hasn’t seemed to be negative for my shooting so far, the less zoom I have, the more fisheye the image seems.Pros: *Great packaging *Well built *Very sturdy *Enhanced field of view *No issues with focusing *No issues with ISO *No issues with high shutter speedsCons: *Lens corners visible in images unless zoomed to approximately 22mm

Pensé mucho en comprar este adaptador, ya que los lentes Macro son carísimos. En mi caso, tengo una Canon R100, y pensaba en comprarme un lente 10-18 mm pero está carísimo. Vi esta opción basándome en algunos comentarios y en las imágenes de muestra en los anuncios del producto. La verdad es que si cumple con ampliar el campo de la toma fotográfica, sin embargo, no queda una imagen por completo amplia y cuadrada, se ve como si fuera un ojo de pez además de que los bordes del mismo lente salen en la fotografía. Conclusión: si quieres un macro que no salga con efecto ojo de pez y no se vean los bordes en la fotografía, ahorra para el lente 10-18mm, que es lo que yo haré. Si no te importa el efecto ojo de pez y que se vean los bordes en cada foto, adelante, cómprate este “lente”. Los materiales y el cuerpo del “lente” se sientes durables, ni de baja calidad ni de alta calidad.

Actualmente estoy realizando pruebas y aun no tengo fotos definitivas

Both the macro portion and the wide angle portion works as advertised The macro portion can be partnered with extension tubes to get really close focussing distance.
