Early in my career I wrote instruction manuals for software. Users would frequently call tech support to ask questions that could answer for themselves would they only Read The F$#@ing Manual, or RTFM. Despite this, I almost always put film into a new-to-me old camera without RTFM. I get away with it most of the time. I did not when I shot this Olympus OM-4T.

Olympus OM-4T

The OM-4T, known as the OM-4Ti in some markets, was the last of the professional-grade cameras in Olympus’s wonderful OM series. Olympus introduced it in 1986 and manufactured it through 2002, making it among the last manual-focus 35mm SLRs produced. It’s a terrific camera — after you RTFM to learn how to use it.

Olympus OM-4T

It’s solidly made with titanium top and bottom plates, yet it manages to be light and easy to carry. Like all OM-series cameras, it’s small. It’s well featured, beginning with an electronically controlled cloth focal plane shutter with a top speed of 1/2000 sec. and a slowest speed of 1 sec. in manual mode and up to 2 minutes in aperture-priority mode. It meters through the lens in center-weighted average and three spot modes. The viewfinder includes dioptric correction for those of us with aging eyes. An innovative new electronic flash control system allowed flash sync from 1/60 to 1/2000 sec.

Olympus OM-4T

The OM-4T takes films of ISO 6 to 3200. Here’s where it’s important to RTFM. Like many SLRs, the ISO setting is around the rewind knob. It only looks like the ISO selector on so many other SLRs — it doesn’t work like them. To select ISO, lift the collar on the outer knob and twist. But unlike every other SLR I’ve ever used the exposure compensation setting moves too. After you select ISO, lower the collar and twist the exposure compensation setting to where you want it. So nonstandard. So much need to RTFM.

I didn’t notice that the exposure compensation was at -2 and proceeded to underexpose my film by two stops. I loaded some ISO 200 color film and set ISO to 100 as this film looks good one stop overexposed. But because the exposure compensation was still at -2, I underexposed it by one stop. Ten frames into my third roll of film I finally RTFM and realized my error. Argh! Thank heavens for the good latitude of the films I shot.

To shoot, move the lever atop the camera to Auto for aperture-priority mode or Manual for manual exposure mode. An LCD display at the bottom of the viewfinder shows exposure information. In manual mode, you’ll see > | < and a row of dashes, along with your shutter speed. It works like a match-needle diaplay: for proper exposure, adjust shutter speed and aperture until the dashes line up with the |. In aperture-priority mode the LCD shows the range of shutter speeds and a row of dashes. Select aperture and press the shutter button down halfway to meter. The row of dashes moves to the shutter speed the OM-4T selects. If the shutter speed would need to be faster than 1/2000 sec, the display shows OVER and the camera beeps.

The star of the OM-4T show is its multi-spot exposure option. In short, you activate it with the SPOT button next to the shutter button. You can meter up to eight spots and the camera averages them. You can also spot meter for the highlights or for the shadows. The OM-4T then applies exposure compensation to bring out detail.

Two SR44/357 button cells power everything. Glory be, an old camera that takes batteries you can buy at any drug store! Without a battery, you can make a photo but only with a 1/60 sec. shutter.

The first roll I shot in the OM-4T was my last roll of original Agfa APX 100, expired since November of 1998 but stored frozen until my film freezer died last summer. Not only did I shoot this two stops under, but I may have underdeveloped the film. I used Rodinal 1+50, which the Massive Dev Chart said needed 13 minutes at 20° C. That’s what I did, but later I learned that Agfa recommended 17 minutes for this developer and temperature. Argh! But my scanner pulled good things out of a handful of frames.

Masked knight

I made these images as Indiana was reopening from shutdown during the COVID-19 pandemic. Working from home during these times has let me ride my bike more, and I made most of these photos from the bike with the OM-4T slung over my shoulder and across my torso. The body is so light and small it was an easy companion on the bike.


The viewfinder is big and bright enough for me, even though some other reviewers compare it unfavorably to the OM-1 and OM-2 viewfinders. I found having to look down at the LCD panel to be less comfortable than the needle display on the left side of the OM-2n viewfinder. Also, the LCD was a little laggy. None of this is enough for me to pan the camera. I just liked the OM-2n’s needle better.


The camera has no on-off switch, by the way. Pressing the shutter button halfway activates the camera; the LCD wakes up and gives a reading. The camera turns itself off after a while.

One Nine Five

My OM-4T came with a standard microprism/split-image focusing screen. As a system camera, you can swap in any number of other focusing screens if you have them. I prefer split image focusing so I was good go to.

Queen Anne's lace

I live in suburbia, but within five minutes on my bike I can be among the farm fields. This old farmhouse probably dates to as early as 1840.

Old farmhouse

I next shot two rolls of Fujicolor 200. I intended to shoot them at EI 100, but because I’d buggered up the exposure compensation setting I actually shot the first roll and ten frames of the second roll at EI 400. It’s a testament to this consumer-grade film that these images all turned out fine. Fulltone Photo did the developing and scanning.

Holliday Road

I made most of these images on a beautiful morning I took off from work. I got on my bike and rode around on country roads four hours. I’ll write a separate post about the red bridge — it’s restored after being mangled by a too-large tractor.

Holliday Road Bridge

Even though I’m a city boy through and through, I deeply enjoy riding out in the country. It’s peaceful, there’s almost no traffic to contend with, and you get to see lots of great old farmhouses.


I left the 40mm f/2 lens on for this ride. It focuses from 10 inches, making it almost a macro lens.


After I RTFMed and set ISO properly on this OM-4T, I mounted a 50mm f/1.8 Zuiko Auto-S lens and shot the rest of the roll on various bike rides over the next week or so. I can’t imagine riding with many of my other 35mm SLRs as they are so much larger and heavier.

Lane to the old house

Except for that laggy viewfinder LCD, the OM-4T handled beautifully. The controls all felt well-made and smooth under use.


Rewinding film on the OM-4T is a little different from on the OM-1 and OM-2. Press in the R button atop the camera next to the shutter button. Then unfold the rewind crank and rewind away.

I had a fine time with the Olympus OM-4T. Because I never fully took to the LCD display, it never disappeared in my hands like the OM-2n did. But this camera passes my litmus test: if it were the only one I could own, I’d shrug and get on with making beautiful images with it for the rest of my life.

    For some reason, my OM-4 gobbles up batteries like there’s no tomorrow. Not sure what the issue is, but others have noted on various online forums that this is a problem with this camera. Yours does not seem to suffer from this.

    1. Jim Grey Avatar

      I shot just three rolls with this camera, perhaps not enough to gauge battery life. But if it’s true of this camera, it will probably be a dealbreaker for me. It’s why I let go of my otherwise brilliant Pentax ES II: it took *four* SR44s and it blew through them like candy.

      1. Michael Avatar

        Battery drain may be because of the display though one wouldn’t expect a great deal from properly designed LCD vs LED. I guess I never realized cameras from the mid 80s had larger ones like that already.

        1. Jim Grey Avatar

          Thing is, it’s not a big LCD. It’s inside the viewfinder! So I don’t know what would make this camera eat batteries.

      2. Khürt Williams Avatar

        Argh! The battery issue of the Pentax ES II is one reason (weight was the other) I rid myself of mine.

    Hi, thank you so much for sharing your experience and great photo’s. Testimony to the fact a man on a bike with a film camera and a beautiful day are all it takes to enjoy life.
    Many thanks
    Ps Having succumbed to your review of the Om 2n I am going to try to be more resolved not to give in to your nefarious plan 🤔

    1. Jim Grey Avatar

      I think the OM-2n is a more likeable camera anyway, so you’re good to stick with it!

      And yes: a bike ride with a camera truly is the good life.

    I have all OMs except the OM-3. FYI, the OM4 (non T / Ti model) is known to gobble up batteries – the T version was made to replace the OM4 and solve the problem. I like the small size of the OM series and the lenses. I think the Ti is my favorite “auto” camera and the OM1 is my favorite manual in competition with my Nikon FM2n. Nice post!

    1. Jim Grey Avatar

      The fellow who gave me this 4T also gave me a regular 4. It’s a little battered and the rewind crank lever is broken so I haven’t shot it yet.

      I so clearly prefer the OM-2n among the OMs I have (two OM-1s, two OM-2ns, this OM-4T, and that OM-4) that I’m likely to shed OMs down to probably one of the OM-1s (as it was a gift from a friend, and it had been her father’s) and one OM-2n.

    I own an OM-2n and an OM-4. I sold a Ti a year or so ago because I like the OM-2n so much better. The OM-2n feels like it is made better that the 4/4Ti. The wind-on for instance is much smoother.

    1. Jim Grey Avatar

      That’s where I am too – I could shoot just the OM-2n among my OMs for the rest of my life and be perfectly happy.

    The plain OM4 ate batteries as the metering system is always on; putting it on the red B or 1/60 settings only turns off the viewfinder LCD display. So all the time it’s sat in your bag, the battery is slowly discharging! Late 4’s and Ti’s had a modified circuit which turned the meter off after a while, which partially cured the problem.
    I use the spotmetering a lot on mine, especially with slow films like Pan F that are a bit fussy about exposure, and to see if the tonal range will fit on the film I’m using. But it’s surprising how often, after carefully multi spotmetering a scene, you discover it’s the same exposure as the plain center weighted metering came up with…….
    Matrix metering does nearly the same thing, of course, and you don’t have to think about it.

    1. Jim Grey Avatar

      Makes sense. Does capping the lens slow or stop the battery drain like it does on the Pentax K1000?

      The OM-4T’s multi-spot system really does seem like a lot of work for minimal gain.

  6. nigelkell Avatar

    Sadly, unlike the CdS cells in the K1000, the silicon blue cell based metering system used by the OM4 (and OM2) pass an appreciable current in the dark. This isn’t a problem in the OM2 as the cells are only energised when the shutter is released; the viewfinder meter is powered by a separate CdS meter as in the OM1, which is switched.
    The OM4 only has the silicon blue cells, and should really have had an off switch; but to conform to Maitani’s dictum that a camera should be ready for instant use at all times, there was no switch! Apparently the fact that most cameras spend a lot of time not being used slipped by them. But Olympus rather followed their own way in the eighties, and totally misread what photographers would really want.
    I quite like playing with the spotmeter, but really the correct way to have gone would have been a multi segment matrix meter. They had put a basic, 2 zone, version in the OM40. But then, they also eschewed autofocus, which rather sealed the OM systems fate.

    1. Jim Grey Avatar

      Olympus may have missed the boat in the 80s, but the cameras that remain are so right for a good chunk of collectors and photographers today. These are sweet cameras.

  7. Steve Mitchell Avatar

    Great read….my Dad had an OM1, I think my niece may have it now. I have an OM2 on my shelf, but it is not working and probably not deserving of a CLA. I have always liked the small form and the great optics of the OM series, but never really got around to trying one. I think it’s time you tried a Contax 139Q, I would love to see how you think that compares ;)

    1. Jim Grey Avatar

      Yeah, the 139Q is on my list for someday. I’m getting to the point where I’d rather borrow a camera than buy it … eliminates the temptation to keep it!

      1. Steve Mitchell Avatar

        You will be tempted I fear regardless 😉

    I confess to never having opened a manual for all the still cameras I’ve used. The only time I got caught up was with the original Nikon F, I had to look up on Youtube how to actually rewind the damn camera! I WILL however read a manual several times for every new super 8 camera I use, just to make sure I understand what features it does/doesn’t have.

    1. Jim Grey Avatar

      I read manuals only when I get stuck. At this point I’ve shot so many cameras that I can usually just figure them out. That’s how I like it.

  9. Khürt Williams Avatar

    Hi Jim, RTFM indeed! You salvaged most of the images but lesson learned. My wife saw me reading the manual for my new-to-me Minolta XD-11. She looked at me and the conversation went something like this:

    B: Are you reading a camera manual?
    Me: Yes.
    B: Why? You never read manuals.
    Me: I do when I have no idea what I’m doing.

    B smiles and goes back to watching Netflix.

    1. Jim Grey Avatar

      I used to write manuals for a living — good ones, as I had (have) excellent technical writing skills. Yet somehow I feel like reading a manual is admitting defeat!

    You just threw away a treasure there. I’d be happy dumping my OM-2 for the OM-4 anytime.

    THANK YOU, thank you, thank you! I’ve been buggered trying to figure out why my mirror has been locking up and thought I needed to take my OM4T in for repair. If I had RTFM, I would know that without batteries, you can only shoot at 1/60. I found this vital piece of information on your blog. Thank you again for sharing this! 🙏

    Nice review that I enjoyed reading. Have multiple OM-1(n), OM-2(n), OM-4(T) bodies that I grew up using in high school, college and to date. Have about 20+ Zuiko lenses. Love these cameras! One suggested change in your review for clarity and to avoid some readers making a mistake. In describing the rewind procedure, you refer to “pulling up” the rewind knob and then cranking away. As an experienced OM user, I clearly understand you as meaning “unfolding the rewind lever” and cranking away. However, someone unfamiliar with OM cameras could instead literally “pull up” the rewind knob, which would pop open the film back and ruin the roll of film they had finished shooting.

    1. Jim Grey Avatar

      I sold this OM-4T; I just didn’t love it like I loved the OM-2n. I have about 15 Zuiko lenses here as well, including a wonderful 40mm f/2. Thanks for the tip about the language above. I’ll fix it.

        Steve Rosenblum

        Hi Jim–I don’t know if you realize this, but, the 40mm f/2 lenses are selling for thousands of dollars now. Truly insane. Look it up on eBay. The cinematography took a liking to them and have been converting them for use in movies and driven up the prices through the stratosphere. You could sell the lens and buy yourself a Hasselblad or something.

        1. Jim Grey Avatar

          I know. I like this lens a lot, unfortunately. But every time I take it out I’m well aware of how much money I have slung over my shoulder.
