While Kolari Vision might not have been the first company to announce the release of drop-in filters for the Canon EF to RF drop-in filter adapter, they are the first to bring them to market. Kolari Vision has now announced the release and immediate availability of a range of filters designed specifically for the Canon EF to RF drop-in filter adapter.
Breakthrough filters announced their filters for the Canon EF to RF drop-in filter adapter a couple of weeks ago, but they don’t ship until later this month. Kolari Vision, on the other hand, has some of their new range of drop-in filters shipping already. And they have aluminium frames, not plastic, for maximum durability.
There are 19 filters in the range, with one of them still yet to come. Seven of them are IRNDs, which offer an even spread of light-loss throughout both the visible and infrared spectrum, three Infrared filters at 590nm, 665nm and 720nm, their popular IRchrome filter, as well as UV Bandpass and UV/IR Cut Hot-Mirror. While the VND variable ND is still yet to come, a CPL circular polarizer is available.
The IRND filters are the same as those recently announced by Kolari. They’re not like most IRND filters, which attempt to block out all infrared light in order to let the neutral density just take care of the visible spectrum. Kolari’s IRND filters reduce infrared light at the same rate as visible light, meaning that whether you’re working with visible light or an IR-modified camera, their IRND filters should give you the result you expect.
All of the filters use a Gorilla Glass substrate to maximise longevity and are AR/AS coated for easy cleaning and to increase the durability even further. They say the coatings also help to increase transmission and reduce reflection. The non-glass part of the filters is CNC machined from solid aluminium to keep the weight as low as possible while keeping the durability high.
Kolari Vision has also announced a new clip-in filter holder for the RF mount, allowing you to basically turn any RF mount lens (or any other lens via an RF adapter) into a rear-filter lens. The goal is to allow EOS R cameras to be stripped off all of their wavelength-blocking abilities, replacing them with the rear-filter behind the lens.
The clip filter then goes inside the lens mount to cover the sensor and block whatever you don’t want it to see. This is similar to how the Sigma SD Quattro H works. The sensor itself blocks pretty much nothing and a filter clips into the body to block whatever wavelength you wish to eliminate from your images.
The filters range in price from $99 to $299, depending on which one you need. The infrared and UV/IR cut hot-mirror filters are $99 and the CPL circular polarizer is $119. IRchrome is $199 and UV bandpass is $299. But all of them are available to buy now from the Kolari Vision store.
The IRND filters range in price from $129 to $169, however, they’re currently only available to pre-order. Still to come is the variable ND filter, but there’s no price on that one yet, nor any indication as to how many stops of range it will have.
