Having a good viewfinder amplifier is like a pair of bright eyes! Please look for the Bresson brand, quality assurance!
1. Why use eyepiece magnifier:
Most people have felt pressure on the viewfinder of a digital SLR camera. This is because most of the digital SLR screens are only traditional in size.135mmSLR camera1/1.5, So the image seen from the viewfinder will be relatively small.prefix = o
APS-CIf the model’s viewfinder magnification can reach0.75-0.95Times, it’s already quite high, which is considered to be a medium focus in a digital SLR50mmThe standard value of the lens. However, if you want to compare with a traditional film camera, you must divide the data of the converted focal length by the data of the filter magnification.(Nikon,Pentax,KonicaMinoltaThe words are1.5,CanonThe words are 1.6).
The eyepiece magnifier is installed on the eyepiece, you can get1.08-1.58The multi-fold viewfinder magnification effect is suitable for macro and remake photography that require precise focus and composition. At the same time, it prevents stray light from entering, facilitating clear viewfinder.
The so-called viewfinder magnification refers to the ratio of "the size of the subject seen by the naked eye" and "the size of the subject seen by the viewfinder". If the image seen by the viewfinder is the same as the size seen by the naked eye If it’s the same, the filter magnification is1Times, if the magnification number is less than1, It means that the viewfinder image is smaller. The above is when the device is in a standard lens(135mmThe traditional camera is50mmLens), The field of view is set to the standard state and the shooting distance is infinite. If135mmSLR camera is0.7-0.84Times.
If the digital SLR is converted to135mmThe specifications of traditional cameras, even high standardsPentax *ist DS2(Viewfinder magnification0.95Times)orNikon D200(Viewfinder magnification0.94Times)Is only quite0.63Times whileCanon EOS 20D(0.9Times)Approximately equivalent to0.56Times,Canon EOS Kiss Digital N(0.8Times),Nikon D70s(0.75Times)Equal to approximately0.50Times, and135mmCompared with traditional cameras, it is a bit powerless!
Bresson eyepiece magnifier (eyepieces)It is a product developed to solve this dilemma. Just attach it to the viewfinder of a SLR camera to enlarge the image by approximately1.08-1.58It can support most cameras on the market.
Be applicable:
1,Presbyopia,MyopiaThe must-have mirror for playing SLR:Adjustable diopter（±250 degree adjustment）. As the camera''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s diopter adjuster is adjusted to the limit, the player whose naked eye view is still blurred, install this product, generally speakingPlus the camera''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s diopter,Within 500 degrees of myopia and 200 degrees of presbyopia, the view can be taken with the naked eye. It is equivalent to putting on glasses for the camera.
2,Focus assist: Enhance the ability of manual focus. (Although the eyepiece magnifier can improve the manual focus ability, it is still relatively limited. The best solution:【Bresson】Split image focusing screen+Eyepiece magnifier to improve manual focus accuracyNExperience the precision of manual focus in the film machine era. )
3.Anti-fog:After the eyepiece is installed, it protrudes about 15mm from the camera. The hot air exhaled from the nose and mouth avoids condensation on the eyepiece glass. At the same time, the coating also has an anti-fog effect.
4. Avoid touching or dirtying the LCD screen with your nose.
5. Better viewing experience: many cameras can only do itWith a magnification of about 0.94 times, it is equipped with a finder magnifying glass for more realistic framing.

*Some cameras with eye-control LCD display/off function, equipped with this eyepiece magnifier, will block the eye-control photosensitive spot, please turn off the eye-control function to use it.
3. Matters needing attention:
1. Please do not remove the viewfinder from the camera frequently. It is best to fix it on the camera for a long time, and store it together with the camera in a dry, sealed, and suitable temperature environment when not in use.
2. This viewfinder is designed to prevent disassembly, please do not disassemble it yourself.The viewfinder is a precision optical instrument. Please act lightly when adjusting the diopter. Do not adjust it too hard.
3. When people wearing glasses use this eyepiece, due to the lens barrier, the eyeball is farther away from the viewfinder than the naked eye, and the viewing angle will be narrowed and restricted. If the viewing corner is blocked, you can turn your eyes to view the view, or clockwise Rotate the eyepiece to reduce the magnification to eliminate this situation
4. The material of the silicone eye mask is soft and smooth, and the coefficient of friction is smaller than that of rubber. Although it is already tight during installation, please be careful not to rub things in order to avoid falling.
Four, installation guide
General APS SLR, up to 1.58 times can zoom in panoramic view without obstruction, a small number of camera viewfinders are designed with narrower angle of view, and the corners may be slightly obstructed. The full-frame camera has a wider viewing angle. If the highest magnification is obstructed, the magnification can be adjusted to increase the wide angle of view and remove the obstruction. Of course, there are also some photographers who ignore the slight occlusion in order to achieve a sharper focus. This eyepiece magnifier can be adjusted between the magnification and the viewing width to meet your various shooting needs. When wearing glasses, the distance between the eyeball and the viewfinder increases due to the lens barrier, and the angle of view is narrower than that of the naked eye. Therefore, the degree of occlusion of the corners may be earlier than that of the naked eye.
