Questions & Answers

Shopper : is this for people that wear glasses ?DEBORAH A : Wearing glasses is not a problem.GEORGE B : The eye piece is for anyone glasses or not. It simply replaces the original eye piece so it can used with the HydrophobiaCHRISTOPHER M : Not sure, since I wear contact lenses and not my glasses. I'd imagine Think Tank could answer your question.LOUIS M : The only function of the Think Tank Eyepiece Adapter is to replace the Nikon external plastic eyepiece on the camera. The adapter will allow the Hydrophobia cover to properly fit around the eyepice to seal out any water.ELIZABETH W : This is not a corrective lens. It can be used by an eyeglass wearer. It does not invert to accommodate eyeglass lenses (i.e. in the fashion of binocular eyecups). This attaches to the eyepiece on the camera. It slots into place. It has a grooved edge. The rain cover has a round, cut-out foam-rubber gasket area in the clear vinyl window over the back of the camera. The eyepiece "buttons" through the gasket area, allowing the user to see directly through the viewfinder. The "buttoning" through also helps keep the raincover aligned correctly on the camera in use. The gasket is tight. It sits beneath a clear vinyl flap, which is secured by velcro, to prevent it being a weak spot in the waterproofing. You do need to buy this to have the best possible fit and performance from the rain cover. I found the raincover to be effective, but in extended use my hands would get very sweaty, reaching up the sleeves to hold the camera. It is possibly most useful on a tripod. It did protect a camera with a long lens very well from mist, rain, salt spray, splashes, and general airborne stray water. Keep in mind that it will not protect from a ducking, though. The clear vinyl gets smeary with sunscreen and is not easy to keep clean. Have a couple rags in your bag.RICHARD D : No it's mainly there to seal the camera and the Hydrophobia. You can use with or without glasses.JONATHAN F : No, this is intended to be used with the Think Tank Hydrophobia to prevent water from entering the rain cover and getting the camera wet. There are no corrective lens properties to this eye piece. It temporarily replaces the eyepiece of your camera while you are using the hydrophobia. Once done, it would be best to put your original eye piece back on, as this one has a gap that is used to connect the rain cover, so it is not comfortable on it's own without the cover.JASON B : No, this is the eye cup that replaces the standard eye cup when using the think tank rain cover to seal the camera body from getting wet. This eye cup has no diopter correction to itRUBEN C : No, it will replace the eyepiece you have on your camera while you use the Hydrophobia. It's to give you that water tight seal on your eyepiece. So when you go to use the Hydrophobia you take off your eyepiece from the camera and put the Hydrophobia with this eyepiece on. Once you are done using the Hydrophobia, you then resume using your normal eyepiece. I hope that answers your question. If the question is if people with glasses can or can't use this eyepiece, you can as I wear glasses pretty often and I have two Hydrophobias.Dale L : Yes, I wear glasses and it works fine for me so, I don't believe this will be an issue for you. Hope this helps!
Shopper : Is this compatible with the Nikon D700 and D7000 ?ERIC L : Will not work with D700, that body requires the screw in version. ERIC L : It works perfectly on my D7000.
Shopper : Why Did You Choose This?Roberta A. R : It will help with the glare on my viewing lens.DUANE F : To protect my gear from rain in Florida

Hydrophobia Eyepieces

Longtime photojournalist/photographer who has worked in all manner of miserable conditions. The Hydrophobia eyepieces are a seamless fit for my Z9 and makes shooting in rain/seas spray/wet snow a non-concern. Solid product!

Hydrophobia Eyepiece for Z9

After getting my new Nikon Z9, I was very happy to get the matching Hydrophobia Eyepiece so I could use my new camera with my rain cover to cover a rainy sporting event. Eyepiece worked very well

Better than factory.

I am so happy with the Hydrophobia Eyepieces. I purchased them to use with my rain covers, but they work so well I now use them every day and purchased this extra set as backups. I wear glasses and shoot sports. This eyepiece is perfect for everyday. Of course I have used them in heavy rain with great results too! Thanks for a great product.

extends value of rain covers to a new camera.

I have several of the current rain covers for different lens /body combinations and after buying a new camera I wanted to keep using them. This gives me the option of keeping my current investment useful.

Fine addition to the Hydrophobia camera/lens cover

I used my 600mm Hydrophobia lens cover in a light rain for my Nikon Z7 -without- the eyepiece. Big mistake. Now, with the fittable eyepiece, I feel much more confident

hydrophobia eyepiece - better than OEM

I have put Hydrophobia eyepieces on my cameras for a number of years and feel they are better than OEM eyepieces. They also work well with the Hydrophobia rain covers!

New Nikon Z9 Hydrophobia Eyepiece is great.

I've been using Hydrophobias for my cameras for years primarily in rain, snow, zodiac salt spray and desert blowing sands. When the new Nikon Z9 came out, I was disappointed that it required a new eyepiece for my Hydrophobias, as the Z9 has an entirely new design for the eyepiece socket. Now that Think Think has been shipping their Z9 eyepiece I'm able to use my Hydrophobias again. It's worked extremely well and I couldn't be more pleased with its performance.

Hydrophobia Eyepiece for Nikon

It is solid, robust, locks in place, and works well with the cover. Oh, and people who see it for the first time keep asking what this thing is. Definitely a must have if you also own the rain cover.

EP-F fits Fujifilm GFX100

While not listed specifically for this camera, the EP-F eyepiece does fit the Fujifilm GFX100. Great tool for providing EVF access while protecting the waterproof seal of the rain cover.

A Really Nice Improvement

I photographed my first Elk in Yellowstone using the original rain cover for a 600mm lens. When i took the shot, it was misting at first, then began to rain lightly. My equipment was never in danger of getting wet. A great product made even better. Thank you Think Tank. George Ligon

Another quality item from the ThinkTank crew

I already had the necessary eye pieces to fit my Nikon D750 so when I purchased a D850 and D4s I needed the different connection type. No hesitation to get this. The rain covers for the 70-200 and 300mm lenses are top quality and beat anything else I have tried to keep out the rain.

Great system

Different camera, different eyepiece needed...affordable, interchangeable eyepieces are a hallmark of this great system. Every time I'm at an event I have to chuckle at the collection of garbage bags, shopping bags, even towels I have seen other photographers using to try to keep their equipment dry.

I love my Sony but the darn eyepiece keeps falling off. ThinkTank’s eyepiece solves the problem . This is made for diving, but works great all round and does not fall off at random.

Great piece, doesn't work with the Z-series Nikons.

This piece blocks the EVF sensor that dictates when it should be on live view or EVF mode, forcing you to lock in either priority modes.

Hydrophobia® Eyepieces

After using other eye-protectors on my Canon 5D Mark IIs I switched to the Hydrophobia® Eyepieces. Did a bunch of research and review reading deciding this was the correct move. I didn’t purchase these for waterproofing although that’s built in, but for comfort wearing glasses all the time and leaving my LCD completely clear for checking shots on the go. My LCD was partially blocked by the eye piece I’ve been using for many years and also always found moisture on the screen from touching it with my face. None of this happens now! Been on a number of shoots since my purchase and you will be happy with this product. Remember “THINK TANK” is all about the preparation before the product hits the street.
