A short time back, Bravin Neff posted a thread concerning a product he has produced calls the "Grab Focus Lens Cover" See: https://www.mu-43.com/f38/protect-your-lens-45909/. The product concept is a simple one: The Grab Focus Lens Cover is a cover or skin for various Mu43 prime lenses that is intended to protect the lenses from damage. Nothing more, nothing less. Bravin is producing covers for the Olympus 12mm f/2.0, Olympus 45mm f/1.8, the Olympus 17mm f/1.8, the Panasonic 25mm f/ 1.4 and the Panasonic 20mm f/1.7. This review is for the Olympus 12mm f/2.0. In the box For the Olympus 12mm f/2.0, the box contains three (3) items. 1. A cover, 2. a small plastic ring, and 3. Instructions. The instructions are decent, thought installation is pretty intuitive. My suggestion to bravin would be the addition of material clarifying the role of the plastic ring for the Olympus 12mm and 17mm lenses. Installing the Cover Installing the cover on the Olympus 12mm f/2.0 (and the 17mm f/1.8) requires putting the lens in auto-focus mode with the focus snap-ring in the forward position. A plastic ring is then placed around the lens behind the snap focus ring in the channel that allows the focus ring to travel back to the MF position. This insures that when the cover is installed from the front, the focus ring is not pushed back into the manual focus mode, disabling autofocus. The camera can still be placed into manual focus mode, but this must be done through the menus as opposed to by snapping the focus ring back. The cover is then installed easily over the lens by pushing it from front to back over the lens barrel. The cover itself is a plastic material and fits nicely over the lens. It is in most dimensions larger than the lens and has a strip of plush material on the interior which snugs up against the focus ring and holds the cover in place. When fitting the cover, this plush material comes in contact with the focus ring and establishes a very nice snug fit that takes just enough force to be positive without feeling overly tight or forced. Cover installed with 46mm filter (Panasonic G5 with P14-45mm) Fit and Finish The fit overall is very precise and the cover does not in any way wobble or have play. Thanks to the precise fit and a very fine focus ring mechanism on the Olympus 12mm f/2.0, focusing with the cover on is very smooth and unhindered. The fit at the front of the cover is also quite precise, and it stops perfectly at the edge of the lens allowing filters to be attached normally. The fit at the back of the lens is also quite precise, leaving just about one millimeter of clearance from the base, which I assume helps with insuring that it does not foul the body. The build quality is quite nice. The cover is significantly more rigid than I thought it would be. It appears to be quite durable. The color is black and the finish in normal use appears to be a semi-gloss; the color and finish are a nice complement to the black OMD EM-5 with which I use the 12mm f/2.0. The photographs in this article tends to show it as being a bit more shiny that it looks in practice, and this mostly attributable to the use of flash. In Practice I do not like pouches. While pouches are all very nice if you do not use your lenses much, I need ready access. I tend to shoot in some difficult and even dirty locations. I usually never put my bag or equipment on the ground. Messing around with pouches represents another potential point of failure for me. Dropping my lenses or anything else because I am trying to get a lens out of a pouch is not something I relish. I also tend towards minimalistic bags and pouches simply defeat this in too many ways. The idea of an integral cover that will protect my lens in the bag and on the camera body is therefore compelling. With the 12mm it is possible to grip the lens firmly enough to remove the lens with the cover on. On the other hand, I have not been able to put the lens on with the cover in a positive enough manner to trust that I've really sent the mechanism home. It can be done, but may represent a risk. This is a small thing, and sliding the lens cover forward half and inch for both removal and installation is an easy, quick and intuitive operation and insures that the lens is properly seated/unseated and that one has a good grasp of the lens. It should be noted that the cover has a small index mark that allows the orange dot on top of the lens at the rear to be seen. It is helpful for lining up the lens for installation, etc., but is really not required if one opts to install the lens while the cover is off or pushed a half an inch forward.. It should also be noted that with the Olympus 12mm f/2.0, the cover extends to the end of the lens barrel. While the fit is such that you can install filters, the OEM hood will not fit over the lens cover. There are three possible solutions: 1. Trim the hood to the appropriate distance so that the hood can be installed; I ran this by Bravin and it seems this would not compromise the integrity of the product. I believe he is considering offering a model that allows for installation of the OEM hood; 2. Put a wider 46mm filter on the end that will allow the OEM hood to gain purchase. I don't recommend this, nor have I tested the idea. Frankly, I'd hate to find that it vignettes, and it would mean tracking down wide filters in an era where the thin filters are the easiest to find. The third possible solution is one that fits with how I already use the lens. I use a 46mm to 52mm step-up ring. To that I affix 52mm filter. I then use a "Perfect" Hood for the Sigma Super Wide II 24mm f/2.8 lens See: Sigma Perfect Hood for Super Wide II 24mm f/2.8 lens on eBay! This hood is made for a FF 24mm lens. When properly installed on the 12mm f/2.0 it does not vignette in any aspect ratio. For me then, this is a perfect setup to use this cover, and a lot less expensive. Since the hood removes very easily, it makes removal of the lens by partially removing the cover quite simple, and really not all that different than how I would do things normally. Camera with 46-52mm step-up, 52mm filter and Sigma Perfect hood (Panasonic G5 with P14-45mm) Discussion I did take the cover on a shoot in an abandoned factory. I do not have the material from that outing processed yet, but this is shot in the same location. While the idea of a hood protector may not be useful to some, I find it a relatively compelling proposition, especially in the conditions depicted above. I routinely shoot photos in difficult conditions like this - dirty at best and even a little toxic at worst. I sometimes get into tight places where there is a lot of rusty, twisted metal over which I have to climb or through which I must navigate. I also shoot landscapes and at least a couple of times per year I do some moderately difficult hiking to get to locations that are not exactly roadside attractions. I like to use my equipment and at times I am much less focused on the equipment and a little more focused on getting the shot. A little protection is really nice to have, especially where it does not get in the way and is simple and straightforward to use. The 12mm is a favorite lens. Having a little extra protection for this lens is great. The cover does seem to seal the lens a little from foreign matter and while not weather sealing, it is better than nothing. The cover's tactile feel is slightly warmer to the touch and a little larger in terms of diameter than the 12mm's focus ring. To me it feels similar to the focus ring on the Sigma 19mm and 30mm, though a little wider - perfectly acceptable though not perhaps as satisfying (in theory) as the feel of cool metal. Yet this is the kind of thing I really do not notice in the field. When I am focusing the camera in pursuit of an image, the tactile feel of the lens simply does not tend to permeate the experience much - unless it somehow gets in the way. Like I said, I did take the cover shooting, and it did not register really at all other than that i was glad I had it. What did register was that at the end of the shoot there was a fine dust on the camera and cover. I removed the lens, put a body cap on and wiped the body. For the lens I removed the cover and rinsed and dried it. I did not detect any dust on the lens beyond the front element (filter). Another reason I like the cover is that compared to the silver 12mm, this makes the camera and lens a little less obtrusive. I routinely walk around in a city that is considered the sixth most dangerous in the country. Low profile is better. I will say that I consider it a benefit that it is black, and if I could have afforded the limited lens I'd have bought it. But if you are looking at this cover solely to turn you lens black, just buy a black lens. Other than the 12mm, Olympus and Panasonic sells them that way. But if you want something that can provided a modicum of protection both from dings as well as foreign matter, and which has a nice tactile feel, this is a good product that is well thought out, fits well, and simply gets the job done. Pros 1. Provides good protection from dings 2. May add a level of dust resistance 3. Removeable/washable 4. Nice build quality, nice feel 5. Matte black finish matches black EM-5 nicely Cons 1. No provision for OEM hood in this version (this does not affect me in the least) 2. Best to remove it or push it forward when installing/removing lens (for me this is well worth the trip) 3. Manual Snap Focus is compromised, though MF remains available through menus. I personally feel this is a great product. Overall it represents a simple concept that is nicely executed - it fills a need for some of us very well and too much should not be read into it. I do not worship my gear. But I do want to keep it nice without having necessarily to "baby" it. Perhaps it is most similar to the idea of an LCD protector. If someone was selling a lens and stated that it had one of Bravin's covers on it "from day one," I'd almost certainly feel this was a bonus. Thanks for reading woof!
