TODO alt text

Benro’s new filter system would not simply tick all of the bins for filter followers, it provides in some intelligent concepts that you just will not see anyplace else.

Like different filter programs, it is available in two components: the filters themselves, and the filter holders. The filters embody graduated ND (impartial density) filters for firming down vibrant skies which might in any other case be overexposed, round polarisers for darkening blue skies, bringing out clouds and subduing reflections, and ND filters for decreasing general publicity and permitting the lengthy publicity occasions wanted for these stunning ‘milky’ water results the place uneven water takes on a silky sheen, and surf turns right into a smooth, smoky blur.

For graduated filters you want a sq. filter system with the intention to slide the filter up and down in its holder to place the transition from gentle to darkish proper on the horizon, and Benro gives two. The FG100 is a daily inexpensive filter holder for extra cost-conscious photographers, whereas the premium steel FH100M2 holder is the one examined right here.

The important thing factor in regards to the FH100M2 is its geared vertical positioning system. You do not slide filters immediately into the holder within the regular means; as an alternative, you match them right into a slim rectangular body first. The holder comes with a 100 x 100mm sq. body and a 100x150mm body for ND grads, that are taller. As soon as the body is slotted into the holder, you’ll be able to wind it up and down in small, exact increments utilizing an adjustment knob which engages with a toothed ridge on the filter body.

We additionally tried out a choice of Benro’s premium glass filters, that are coated fairly than dyed like common resin filters, for better longevity and stability. These are fairly dear in comparison with resin filters, however you should utilize Benro’s cheaper resin filters within the FH100M2 holder too, or the glass filters within the cheaper FG100 holder if it involves that. In truth, these filter programs are largely standardised throughout producers, so you might even keep on utilizing your current 100mm filters and migrate to the Benro package at your personal tempo.

Construct and dealing with

The FH100M2 holder comes with 82 and 77mm filter rings, however we used it on a Nikkor 18-105mm lens which wanted an additional 67mm step-down ring, purchased individually. You screw the adaptor on to the entrance of the lens, then hook over the filter holder which is then held in place by a spring-loaded clamp. You tighten this down if you’ve obtained the filter holder rotated to the right angle to your graduated filters.

Becoming the filters to the frames solely takes just a few moments as soon as you have obtained the grasp of it, and you’ll then modify as much as three filters (there are three slots) by pushing the adjustment knob out and in to interact with each it flip. It is rather more exact and controllable than common friction matches.

In case you want a round polarising filter, this screws into the filter holder, the place it may be rotated independently through a toothed wheel on the again of filter. You possibly can then flip the polariser to get the specified impact with out disturbing the opposite filters – it spins with simply the correct amount of resistance.

The design, supplies and controls are first-rate, however there’s a specific amount of fiddling about that goes with them so do not anticipate to be on top of things immediately. Your first picture session is more likely to be spent merely getting used to how this Benro filter holder works.

Benro used a fancy optical collimator to point out the impact of inserting common resin filters into a lightweight path, its personal resin filters after which its glass filters. The outcomes confirmed an apparent enchancment within the sharpness of a check goal with its personal filters. An optical measuring instrument like this does not precisely replicate real-world taking pictures, nevertheless it’s an fascinating comparability nonetheless. The goal, in fact, is to create filters that produce the minimal doable picture degradation.

Sharpness is just one issue, color shifts are one other. ND filters and grads often produce color shifts, and when you can appropriate this in software program later, nevertheless it’s greatest if you do not have to within the first place. Our pattern photos confirmed no discernible color shifts or lack of decision – or, if there was any, the degradation was too small to note.

Premium-quality filter programs aren’t low cost, however should you intend taking pictures high-quality landscapes they do make a distinction, not simply in image high quality however ease of use and longevity. Benro is pitching each at newbie/fanatic digital camera customers with its fundamental FG100 holder and resin filters, however with the intelligent FH100G2 holder and glass filters we tried out, it is going for consultants and execs. 

Prime-end filter programs aren’t low cost, so a full package may price as a lot as a brand new lens (ouch), however the excellent news is that these filter programs are interchangeable – you should utilize your current 100mm filters with this new holder, or Benro’s new premium glass filters along with your current holder. You possibly can migrate to Benro’s new system at your personal tempo fairly than paying for it suddenly.
