I mainly use filters Hoya and marumi... There are several more expensive B&W filters available. The main task of conventional filters is to protect the lens from external damage. UV filters are used for this task. In theory, they should protect your photos from UV radiation. In fact, it doesn't affect anything. Or rather, it’s good if your protective filter does not affect anything. Bad - when the filter makes changes to the image. This applies to too cheap filters costing up to $ 10.
About the cost
The cost of the filter depends on the following factors:
frame thickness (regular or slim)
show-off of the manufacturer (filters that do not scratch and last 100 years, etc.)
From the last bought by me - filter Hoya fusion antistatic 82mm. I bought it for the lens Canon EF 16-35mm f2.8L II with a filter thread diameter of 82mm. This filter is marked Super slim frame, which means a thin frame that houses the glass. For wide angle lenses, this is very important because a typical 16mm filter will likely produce slight vignetting. Non-slim filters can be safely purchased for lenses from 35mm.
If you look cost of these filters, you will notice that the price increases with the size, but not much. The filter costs about $ 20. and it's inexpensive.
I also have green ones Marumi DHG filters... They are still red - with big show-off. DHG signifies that they are intended for digital cameras, which is what we need. These are also inexpensive filters.
In addition to protective filters, you will need others sooner or later. For example, neutral density filters (ND filters), polarizing filters and filters for infrared photography. Less popular Glow Mist filters.
Below you see the Hoya HMC ND4 58mm neutral density filter and the Hoya Infrared 72mm infrared filter. With a suitable diameter for different lenses, you will be assisted adapter rings.
There are variable ND filters in nature, but they are generally inferior in quality to filters with a single shade value.
If you have a Fujifilm camera with a Fuji X-mount (X-T3, X-T4, X-S10 and many others), then you probably felt the problem of the high cost of native optics for this system.
One way to solve this problem is to purchase an adapter to use the cheaper Canon lenses on a Fujifilm system.
Canon-Fujifilm adapters are different
The Fringer adapter is just one of the options, and it's not the cheapest one. A slightly more inexpensive option is VILTROX EF-FX1 adapter.
Moreover, there is both a conventional autofocus adapter and Viltrox speedbooster for Fujialmost eliminating the crop factor. The problem with it is that it also relieves you of autofocus, which is not at all interesting. Autofocus is declared there, but in fact it does not work normally.
After conducting a thorough research of the adapter market, I was convinced that the best autofocus is preserved with the Fringer adapter. Its closest competitor Viltrox at the time of my research was frankly inferior in AF quality. Perhaps at the moment the situation has leveled off. You can find out only by purchasing both adapters and comparing them (which I am not planning to do). Both adapters are equipped with a micro-usb connector for firmware updates, with which the manufacturer adds support for new Canon lenses and fixes old bugs.
The Fringer EF-FX II adapter is available in two versions: EF-FX II and EF-FX PRO II... The “PRO” version for professionals features an aperture ring, just like the original Fujifilm optics. It's a matter of taste - whether to overpay for it or not. If you do a good search, you can also find the cheaper first Fringer EF-FX adapter without the II digit. But not worth it, it will work worse.
So how does the Fringer EF-FX II autofocus work with Canon lenses?
The results of their tests with the camera Fujifilm X T3 I have outlined in this video:
If you add up, then everything is fine for photography. Canon lenses that I tested can be safely used for photography on Fujifilm X-mount cameras.
But with video filming, not everything is so smooth. Tracking autofocus works well. I shot with confidence with the Canon EF 35mm f2 IS on a Fuji X-T3 and a gimbal. It monitors well and a good bundle comes out with the camera installed on the gimbal. There are problems if you want to shoot with eye focusing for extended periods of time. I have tried many times to shoot for your YouTube channel with Canon optics on Fujifilm cameras and I will say that the result is unpredictable. There were videos where the camera with the adapter worked with a bang and the focus remained on me. And there were where the focus crawled back and forth and went to the background.
From my experience, where autofocus with the Fringer adapter did not work at all, these are the Canon EF 24mm f2.8 IS USM and Canon EF 15-85 3.5-5.6 IS USM lenses. In general, on the website of the adapter manufacturer, there is a list of supported optics. Over time, this list grows. By the way, someone wrote to me that the Viltrox adapter supports EF 15-85 3.5-5.6 IS. Again, the Viltrox website also has a list of supported optics.
Conclusions: should you buy the Fringer EF-FX II adapter?
If you only need lenses for photography, then yes - you can. If for video filming, then it is worth considering who and how you will shoot. Such a combo is not suitable for shooting yourself, tk. focus on the eyes is unpredictable during prolonged work. If you act as an operator and shoot someone, not yourself, then you can use such an adapter, because you can correct its work at any time.
The main audience who are interested in such an adapter, I consider the owners of Canon optics, who want to adapt it to Fujifilm. Because buying a camera from scratch and relying on third-party lenses is not quite the correct formulation of the question.
I made sure that Viltrox lenses for Fujifilm they work excellently in autofocus and the AF quality sometimes even surpasses the native Fujifilm optics. Therefore, if you need a fast prime lens, then it is much more reasonable to buy Viltrox on the native Fujifilm X-mount, and not to play with Canon adapters and lenses. So, for example, I have already repeatedly conducted many hours of streams with a lens Viltrox 23mm f1.4 and tracking autofocus on the eyes did not fail. When working through an adapter, the performance of such a task is a big question.
In addition, Canon's full-frame lenses with an adapter make the camera bulky, heavy and unaesthetic. Therefore, I repeat, it makes sense if you already have such optics in stock and do not want to duplicate it by purchasing expensive Fujinon optics.
Where I see the point in the adapter - these are telephones. At Fujifilm, they look frankly losing in terms of price / quality ratio. Canon has some great lenses that Fujifilm can't match in price / quality, these are Canon EF 70-200 f4L IS и Canon EF 135mm f2L... Fuji's counterparts are significantly more expensive. By the way, the optical stabilizer works fine through the adapter. As a budget option from telephoto cameras, I recommend Canon EF-S 55-250 f4.5-5.6 IS STM.
