Fixing viewing in the Nikon FE

Nikon bodies

A few bucks and some sweat equity.

In my introduction to the Nikon FE I focused on the factory’s attention to ergonomics in this elegantly designed camera.

Mine came with a -2.00 diopter Nikon non-standard eyepiece which left much to be desired (meaning I couldn’t see a bloody thing) so I removed the correcting lens, a 19mm screw-in attachment, and had at it while awaiting a plain glass replacement. Nikon is asking $25 for the part which makes highway robbery seem a bargain in comparison, but I traced down a $5 clone on eBay and plonked down my cash. On installation it was immediately obvious that the external diameter is too large, preventing the camera’s back from opening:


Duh! eBay strikes again!

So it’s off to the bench grinder and after marking the right position a small flat is machined on the circumference. The thread is a single start one so, should you ever remove the eyepiece, replacement in the correct orientation is assured.

In practice the larger circumference of the aftermarket part is to be welcomed, providing a bigger contact patch for this snapper’s eyeglasses.

Here it is installed, a spot of black paint applied to the machined flat:


Installed, and correctly aligned.

Now for the other shortcoming of the stock FE body. In my earlier posting, I made mention of the fact that the Nikon FM and FE, and their derivatives (FM2, FE2, FM3, etc.) found great favor with professionals who did not need the bulk and weight of the big F series bodies nor all their flexibility. Nikon did not chintz on the feature set and every one of the cameras in the series – with the exception of the original FM which came a year before the FE – had interchangeable focusing screens. Nikon marketed three types – the stock Type K with a split image center and microprism collar defining the center-weighted metering area, the Type B matte which deleted the split-image aid but retained a microprism center and the Type E, like the Type B but with horizontal and vertical alignment lines added.

The stock Type K screen in the Nikon FE is underwhelming, being both grainy and not very bright. Also, the split-image focus aid partially blacks out with lenses of 200mm or longer focal length, rendering it useless.

However, Nikon did not rest on its laurels. The late 1970s was a fertile period for screen design with easily the best and brightest being the full area microprism one found in the 1968 Leicaflex SL, which remains a standard to aspire to to this day. (The earlier Leicaflex with the integrated, external CdS meter, only had a center focusing spot so it was brighter still, but the utility value was missing). When the 1983 FM2 and FE2 came along the bodies were fitted with an improved screen, the Type K2, E2, etc. Still a bit grainier than you might like but gaining 1/2 stop in brightness. There was more to come for in 2001, with the introduction of the FM3A, the brightness remained but the graininess was gone. This Type 3 (K3, E3, etc.) was the best and the brightest ever made for the FM2/FE series and, amazingly, can still be found new at Amazon for under $30. Continuous improvement, or kaizen, at its best. I bought one.

Do not be tempted to buy a beater on eBay. The new kit comes with the proper tweezers which make exchange simple with no fingerprints on your pristine screen. One end of the tweezers has a rectangular slot to grasp the protruding tab on the screen, as well as a small plastic extension to pop the locking catch in the camera’s body.


This is the right part.

The beater you buy on eBay will likely be filthy (just try and clean those fine fresnel etchings ….) and will probably be missing the tweezers. You really do not want to do the exchange without these. For those interested, the tab on the Type 1 screen has a plain leading edge, that on the Type 2 is notched whereas the Type 3 is engraved with the designation K3, E3 or B3. But however you try to rationalize it, paying $15 for a beater with no tweezers against $30 for the new part makes no sense.

Tweezers. Far more than meets the eye.

Once engaged, the tweezers grasp the tab using a small rectangular frame at their tip.

It’s a magnificent testimony to Nikon’s attention to detail that they lavished so much attention on something as seemingly simple as a pair of tweezers. Note the grip serrations on the tweezers which match those of the focusing collar design of later Nikkors!

So how well does it work? I opted for the K3 as I find the split image center works well for me with lenses all the way up to the 500mm Nikon Reflex and it is much, much better than the stock Type 1 screen, one half of whose split image focusing aid blacks out at 200mm or longer. The microprism collar in the Type K3 works well up to 200mm, starts to struggle at 300mm and is useless with the 500mm Reflex. Measuring the light in the finder eyepiece, the Type K3 screen is one-half stop brighter than the stock Type K screen, and one half stop brighter than the finder in the Nikon D3x, so the state of the art in optical finders appears to have peaked with the Type 3 screen.

‘Subjectively’ is a term used mostly by zonkers, strangers to the objectivity of the technological process, listening to antique stereo gear and paying $1000 for a 3 foot connecting cable, made by Japanese virgins in kimonos; not a one of these jerk offs could pass a blind A/B test. Must get into that business …. But, subjectively, the gain in screen brightness is far greater than the 1/2 stop measured gain suggests. So much so that you really will not want to revert to the stock screen once upgraded. And the gain in the utility of the split image center is reason enough to upgrade. As for themicro prism collar in the Type 3 screen, it seems little changed from that in the Type 1, and works better than the split image aid with very wide lenses.

The 1/2 stop gain in measured brightness means that the exposure compensation dial has to be set to +1/2 stop. More light is falling on the meter’s sensor so you will be under-exposing without this adjustment. Given that you really do not want to use the exposure compensation daily for anything else – because you will forget you have set it in the absence of any finder indication – this is hardly an imposition. After setting the dial thus, I obtained the exact same exposure readings with the FE as on the D3x and on a known external exposure meter.

The FE with the K3 focusing screen retrofitted is now in the 21st century for viewing and focusing.

Nikkor-HC Auto 50mm f/2 lens

Nikon lenses

An ancient lens made even better.

I wrote about the excellent standard 50mm Nikkor lens for film SLRs years ago here. That lens first saw the light of day on the Nikon F in 1964 and Nikon made hundreds of thousands of them, a fair reflection of this optic’s outstanding performance, small size and toughness.

The last version made in the classic scalloped, metal focus collar style came to market in late 1972 and was optically identical with the happy addition of multicoating for better performance when bright light sources were in the image.

I had given away my 50mm f/2 H to a friend when the 50mm f/1.4 came along, that lens’s greater bulk balancing far better on the large DSLR bodies.

The f/2 continued to be made in later mounts with rubberized focus collars through 1979, though the optical formula remained unchanged.

When I recently added a film era Nikon FE to my little hardware collection I found I was hankering for the original 50mm f/2 as its small size would perfectly complement the comp0act FE body, and managed to snap up a mint HC, factory converted to Ai no less, for all of $70. Yes, I could have bought a beater for half that but why would you want to save $35 and suffer mental anguish every time you looked at the scarred black anodized finish which is as ugly as it gets? Here it is, mounted on the FE, the satin black front ring denoting multicoating, replacing the silver one on single coated lenses:

The factory Ai ring adds a second row of aperture digits which is read by the small mirrored assembly in the base of the camera’s prism and reflected into the viewfinder. Nice – you can see shutter speed and aperture through the eyepiece.

Nikon has a remarkably honest assessment of this optic’s performance on its site here and their statement about performance accords exactly with my experience:

The very minor vignetting at full aperture along with mild barrel distortion are both easily corrected using my lens correction profile in PS or LR and, if you install a CPU in the lens then that profile can be invoked automatically when you load your images into LR. CPU installation is very easy as no machining is required and the ‘Dandelion’ CPU can be found from commie vendors on eBay – just search for ‘Dandelion chip’, all of $20. My link in this paragraph includes my installation (Part I) and programming instructions (Part II) and you will not find any better. I have installed around thirty of these and they continue working fine after many years.

Here’s how the lens’s data appear – automatically – in Lightroom, for images made with a digital camera:

I find lens EXIF data extremely useful in the image catalog for, when searching for some long forgotten image, I tend to remember the lens used more than anything else. In the example above the image was snapped on the D2x with its 1.5x crop factor.

Here’s the data on the lens correction profile – while the image was snapped on the D2x, the profile was created on the D700 and that’s what I put in the file name for the profile:

The 50mm f/2 Nikkor is recommended without reservation and can be found in any condition you like for very little. You get Leica Summicron performance for 5% of the outlay and if you drop it, heck, buy another. Plus, it’s better made than the Leica lens.


The f/1.4 is larger and heavier. The epoxy is still drying on the f/2’s CPU!


An old friend. Nikon D2x, 50mm Nikkor H at f/2.

And while I’m at it, if you want a truly unbreakable DSLR in APS-C format for well under $500, you can do a lot worse than the Nikon D2x, which is backward compatible with almost every Nikkor ever made. At 12mp it’s no pixel monster but that’s fine for up to 40″ x 60″ prints and, of course, you make those all the time, right?

Field tests:

You can judge the extent to which the lens vignettes from the sky in these two images:



At f/2, straight out of camera.


At f/2, using my lens correction profile.


Center and edge definition – note the EXIF data from Lightroom in these screenshots, conferred by the newly installed CPU:




Center definition at f/2, 48″ x 72″ print. Note the gentle rendering out-of-focus areas.


Center definition at f/4, 48″ x 72″ print.


Extreme edge definition at f/4.


Like I said, Leica Summicron optics at a fraction of the price. Comparing performance in the extreme corners with that of the 50mm f/1.4 Nikkor of like vintage, the f/2 optic shows no noticeable flare compared with the f/1.4 (probably thanks to the multi-coating in the f/2) and is one stop sharper, meaning that the f/2 is as good at f/2 as the f/1.4 is at f/2.8. That said, either lens will make fine large prints at full aperture, sharp enough to please all but the meanest pixel peepers.
