Nikon F90x 35mm SLR Film Camera and MB10 battery grip

This camera influenced the partnership between NIkon and Kodak to produce one of the most expensive prosumer cameras of the 1990s. However this one is a lot less expensive but with some issues. Let’s have a look at it:

Just couldn’t let this one go. Whilst browsing the sites for my next challenge last evening, this little bundle of joy just popped from one of my preferred sellers for a quick sale, it was about 11pm and was just posted at a sale price of £30:00GBP, however with a voucher I had, I was able to secure it at £27:00GBP. Considering this is a good quality camera of the mid 90s it also comes with the added bonus of an MB10 battery grip, superb value in my eyes. A lot of camera for a very low price.

Here’s a little bit about this camera:

The Nikon F90x is a 35mm autofocus SLR using Nikon’s F lens mount. It was targeted toward the advanced amateur or prosumer; its feature set is comparable to that of Nikon’s current D100/200/300 SLRs. The name N90s was used for marketing in the United States; everywhere else, the camera was called the F90x. This camera was also used as the base for the Kodak DCS 400 series of digital SLRs.

The N90s/F90x was introduced in 1994 and discontinued in 2001. The camera’s predecessor, the N90/F90, was introduced in 1992 and discontinued in 1994. The successor to the N90s, the F100, was introduced in 1998.

Now my experience with this seller is that unless it is absolutely perfect he will not even entertain it. He doesn’t take the time to check and fettle, if it isn’t working from the start he will just get rid of. This attitude of his has meant I’ve had some right bargains in the past with very little wrong with them. I refer you to a recent purchase Canon EOS D60 that had very little wrong with it, but was also a lot of camera for a very low price.

Now I’ve always wanted a Kodak DCS 400 series camera, especially a 460 version as it takes me back to my days when I was working at Kodak in Harrow, I remember when the DCS 400 series came out and back then they were introducing such a new technology that they were commanding a huge price of around $35,000 at the time. These cameras were basically digital versions of the film camera I have purchased above. So whilst I’m on the lookout for a reasonably priced DCS 400 series camera, I guess I will just have to do with the camera that started it all off. And for £27:00GBP I’m not complaining.

I think I may know why this mirror is sticking, and if it is what I believe it to be it could be quite an easy fix. (Famous last words)

So let’s stop all the reminiscing, and wish list writing and get on with this camera’s assessment.

Assessment:

It’s arrived, and as expected it’s a beautiful looking item in an extremely good condition.

The mirror appears to be in a semi raised position, the battery pack is clean with no signs of contamination and battery leakage, so now seems a good time to put in four AA batteries and slide the battery pack into place and secure it.

Battery pack clean and contamination free

Turn the battery on and the mirror clicks back into its closed position. And here I am, probably 40 or 50 actuations later and I can’t recreate the sellers fault of a sticking mirror. The mode the camera is set in, is indicating long exposure times, maybe this has given the impression of the mirror sticking when in fact it’s just doing what it should relative to the light it is seeing. I need to check in clear daylight, but I’m sure this is part of the issue….if there is one.

With a 28-100 lens added

I have a 28-100 lens mounted that I use for testing, the autofocus is working really well and all seems good.

However, take a look at the picture below. It contains two photos of the LCD screen on the top of the camera. What do you see in the top photo that would make you think there is an error?

Is that an error?

For the un-informed, those who are not familiar with this camera or its operation, you will instantly see the letter “E” that is commonly known as an error indicator, in later models it is shown as “ERR”. I do believe the seller has possibly mistaken this for an error code, but if you refer to the bottom photo where I have now installed a test film, it becomes clear that the “E” on this camera represents the word “empty”. No film installed, a simple and easy to make mistake. The bottom picture indicates a film is installed and that 4 exposures have been taken.

As these cameras have in the past been known to have a mirror sticking issue, I will replace the mirror bumper felt. It is well known that when the felt has deteriorated to such a level, the felt becomes sticky, and the mirror just sticks to the felt when it opens. It’s an age related issue that is easy to repair. Even though I have not experienced it with this unit, I will replace it as it will probably fail at some point. I will also check the light seals and replace them if I deem this necessary.

Repair:

The light seals do not need replacing. In fact there are only two small spots of light seals on this camera and both are in good condition.

However the bumper seal was showing signs of degradation, so this has been replaced.

The old seal peels out but leaves a sticky residue behind, this has to be removed with some IPA prior to cutting new foam to size and reinstalling. Whilst I was in the lens are I also removed the focussing screen to clean it and remove the old ingrained dust and dirt.

The area within the mirror area is now clean and dust free after I have used a small air blower to get the last of the debris out of the barrel area. Mirrors have been cleaned and polished and the body cap has been put back on the front of the camera to ensure no further dirt or contamination gets in there whilst I work on the outside.

I’ve printed a hot shoe flash cover purely for aesthetic reasons, I’ve also printed a sync cable cover, for similar reasons, but generally just to ensure any open and exposed areas are covered up. It does make it look a lot nicer.

The sync cable cover also helps keep the exterior tidy as well as protecting the connector.

All I need to do now is clean the exterior of the camera where there is some light dust and dirt. When this is done I will use my usual car cockpit polish to finish the camera off.

When that’s done I will do a quick fly through of all the settings to check if they are all functioning as they should.

Result:

The camera has cleaned up very well and looks glorious. All settings are functioning as expected, and there have been no issues with a sticky mirror or any other issues. The camera is just working well and doing exactly what it should be doing.

I’m using a G type lens so I’m restricted on the type of photography I can do, it stays on its lowest aperture (F:32) but that’s perfectly fine In bright sunlight conditions. I need to purchase myself another lens for testing to allow me the use of the full spectrum of apertures on this unit. That said, my lens has performed perfectly on this unit.

As I’ve stated before, this seller is one of my favourite suppliers as his cameras are always in a good condition, he doesn’t like anything unless it’s absolutely A1 perfect, so this is where i benefit as every unit I have purchased from him is perfect in my eyes, and in many cases need very little doing to them to bring them back into a working condition. This is one such unit.

So, I have yet another lovely piece of 90s “Big” tech restored and working perfectly. The next thing I need to do is to put some film through it. I’ll let you all know when I’ve done that.

Thank you for passing by, have a wonderful weekend, I really appreciate your being here.

Take care.

Sticky, Rubber camera grips

Anyone who has had an 80s/90s/00s camera through their hands would have experienced this at some point. During this time period many if not all camera manufacturers went through the phase of putting rubber hand grips on their cameras. Aesthetically pleasing, and ensuring a good grip of your new “Expensive” toy. I guess, they thought they had got it right. But as with all these good ideas they often come back and bite you right on the bum at a later date.

My particularly sticky Nikon D70

Ok there were probably no recalls regarding this issue, it’s just affected the price of these goods on the second hand after market, and more than likely a perfectly good unit has most probably gone to landfill for no other reason than “Feeling sticky”

Let’s look into the reasons why this occurs.

It’s pretty much down to a process called Vulcanisation. Vulcanisation is a chemical process that hardens rubber by cross-linking polymer chains, making it more durable and elastic. This process, often using sulfur, heat, and other additives, transforms natural or synthetic rubber into a material with improved properties like resistance to heat, cold, and deformation. 

However after many years, the process begins to break down, this causes the rubber to become sticky and in some cases the rubber just breaks down causing traces of rubber dust all over the place. Add to that the normal oils from fingers and palms and the stickiness then becomes highly noticeable, and makes for a very unpleasant experience.

We can’t stop the progress of the degradation, we can however do something about the sticky state, maintain good quality and make the use of the item as pleasurable an experience, just as it was when first purchased. Many believe the stickiness is down to the way the item is stored, and it not being used on a regular basis, as there is plenty of evidence out there of similar aged cameras not suffering from the issue at all, as they are used daily, namely by professional types where these cameras are tools of their trade.

It involves some work, and patience. I am writing this post as I have 8 cameras that i am currently working on, all Nikon D70/D70S and they all have this problem, and they date from 2004.

A load of very sticky Nikons

I use a process that you will easily find on line, the most simple process and it involves using a substance called Isopropyl Alcohol, my one is 99% pure, (also known as rubbing alcohol) I don’t think the purity of 99% is essential but i use it as i have plenty of it around, what with all the circuit board work i do, and the cleaning they also require.

Some people have had results just using a dry cloth and no chemicals, patiently rubbing and rubbing, some for a few hours at a time, until all the mess is removed. If that’s the way you wish to go then fine, i haven’t got the time for all that, i’ll be talking you through the way i do it below, with a chemical.

My technique is simple, lint free cloth and some cotton buds are all that i use, along with a tissue wipe (Such as armoral, or a car cockpit cleaner solution with a dry cloth) and a cocktail stick to finish. The reason for the wipe will become clear at the end.

My Guinea pig for today is a Nikon D70 I have requiring repair. It is a particularly “Sticky” individual and will be a good candidate on how to deal with this sticky situation. This is the process I use on all my equipment that has rubber such as this as part of its structure. It’s worked for me for many years, some people say that it will need doing again after a short while, that’s never been the case for me, and there are a number of documented cases on line where six years after this treatment has been done, there is no repeat of the initial problem. The rubber remains good.

Using a small amount of IPA on a lint free cloth gently wipe the area of concern and you will see the stickiness start to lift, it looks like a glue.

Make your way around the whole camera paying particular attention to those really sticky areas. The IPA evaporates really quickly so you get to see results really quickly. If after one try the stickiness remains then try another application. A good indicator is that when you use a fresh part of the cloth, you see less dirt come off with each application. When you put an application on and come away with a clean cloth, your job is done.

The cotton buds are used for getting into those inaccessible crevices you can’t get into with the cloth. As before as they stay cleaner and pick up less dirt your work is done. All this cleaning and moving about of dirt sometimes transfers the dirt into creases and joins between the rubber and the camera body, this is what the cocktail stick is for, to get into those small gaps and scoop the dirt and debris out. Complete with a final application of IPA in this area and the dirty work is now done.

Now earlier I mentioned about using Amorall wipes or a car cockpit cleaner. Sometimes this process can dull rubber, as you have just removed the layer that was providing the gleaming glory back in the day. You can’t have it all your own way but a good quality interior dashboard cockpit cleaner really does add some shine and life to that old camera and really does do a good job of restoring it. I use Auto Glym interior shampoo on a lint free cloth and apply this by gently applying all over the exterior of the camera. It is now exceptionally clean. A quick rub over with a dry cloth once this is dried and what more can I say? This is a different camera, looks stunning and has lost all trace of stickiness and dirt. Now it has that extra layer of protection as well, it’s now a pleasure to behold.

The finishing touch.

This little task probably took just over 20 minutes to achieve and gives so much satisfaction to me as you can see a cameras appearance change in front of your very eyes, and anyone can do it. No camera deserves to go to landfill just because it has this sticky exterior, it’s simple to do and can revitalise an old and much loved camera.

I hope this has helped with dealing with the stickiness issue, if you ever experience it. I have even heard reports that a good quality window cleaner can also give similar results, but I’ve never tried it, so there really is no excuse if you have a camera in your ownership needing similar attention.

Many thanks for passing by. You legend👍
