A Question about Olympus 8mm F3.5


waltonksm

Recommended Posts

I am contemplating the purchase of an MFT Olympus 8mm F3.5.  I am thinking about a used one that does not cost and arm and a leg.  Dallas had a few comments to make about the 8mm F1.8.... but I find very little about the 8mm F3.5 beyond the initial Olympus announcement when it was introduced. Also, it appears to no longer be in the Olympus "stable."

 

Can anyone give me any insights?  Perhaps the fact it is discontinued is the best indicator. BUT, it still demands a fairly high price on eBay (for whatever that is worth.)

Hi Walton, good to see you posting. 

 

If getting an Olympus 8mm MFT at an affordable price proves a problem, I have had good experiences with my inexpensive Samyang/Rokinon 7.5mm f/3.5 fish-eye.

 

(I may however be assuming that the 8mm Olympus is a fish eye, so please forgive me if I have made  the wrong assumption here.)

Yes, it (Olympus) claims to be a fisheye.

 

I also have another fisheye lens.  A Meike 6.5mm. It is totally manual everything. Manual lens settings; no contacts or cpu on the lens. And it is VERY clearly fisheye.  It might be a hair more than 180 degrees.  It is easy to get my fingers in the shot, when they are on the metal barrel of the lens. 

 

Realistically, I have NO need for another fisheye since I have the Meike.  But AF and auto settings appeal to me. I found it rated to be in EX+ condition for about $250. But tonight I just filed my IRS  taxes on line, and will be getting back about $230.  So I went to a couple of places that are having sales on used lenses.

 

I should be saving up for the M1 Mark III.

Hugh: 

 

You may have just saved me some cash.  I looked again at my research on the lens, and discovered the wonderful price is because it is a FOUR THIRDS, Not an MFT. I do have an extra adapter sitting around someplace. But it does not make  lot of sense to buy a 4/3 lens to just add an adapter.

 

Thanks,

Walton

Walton, the advantage of the Samyang/Rokinon 7.5mm f3.5 fisheye lens mentioned by Hugh is you can use it also to get ultra-wide wide shots when held level. This makes it a very versatile lens.

 

Some examples

Luc, these are great examples of what the Samyang/Rokinon 7.5mm f3.5 can do.

 

Walton, you will probably know by now, but the 7.5mm Samyang/Robinon is like your Meike 6.5mmin the sense that it is also totally manual everything - as you say manual lens settings, with no contacts or cpu on the lens.

 

In practice I have never found this to be an issue, although some form of CPU would be nice from the documentary benefits provided from the meta-data that a cpu lens provides.  But it is certainly no worse than putting a non-MFT lens onto your MFT camera via an adapter.

Walton, I owed that 8mm 4/3 fisheye. It was huge, felt like a hand grenade! IQ was very good, but it’s size made it impractical as a casual carry around for the occasional shot you might make with it.

 

As Hugh and Luc have mentioned you can’t go wrong with the Samyang/Rokinon 7.5mm. Brilliant little lens. If you want to spend a lot more money you can get the new Olympus 8mm 1.8 PRO, which I tried too. Very nice, but very expensive and not justifiably so given the Samyang.

Another vote for Samyang/Rokinon 7.5mm/f3.5.  As it employs the stereographic projection method, it doesn't squeeze the peripheral part of the frame as much as other fisheye lenses do.

 

Unless you are aiming at a distinct fisheye effect, Samyang/Rokinon is more versatile, I think.

Thanks for the great information.  And also for the excellent images.  I need to do a bit more with the 6.5 Meike, and then will look at the Samyang/Rokinon.  I am really impressed with what you are doing with the lens.  The Meike that I have does not appear to be as versatile as the 7.5 that you are using. And the IQ on my lens is not very good.

Very nice, Akira. It's such a fun lens!

 

Thank you, Luc!  Yes, it is indeed a fun lens.  The Samyang and Panasonic GF5 I bought second hand for about 90 USD used to by my dedicated fisheye camera.

 

Also, The Samyang/Rokinon 7.5mm/f3.5 allow close focusing up to 9cm, which makes the lens even more versatile.

OK, you have sold me.  I found a used one in LN- condition for $134 at KEH. Thank you again for your great photos Luc and Akira. Your photos are what really sold me on the 7.5mm.

Well done Walton. You will be struck by how small and light it is, so it will be quite practical for you to take on longer walks.  Just be careful not to put it down somewhere and lose it.

Luc:  These are very nice.  More possibilities for me to consider.

Walton, this might be slightly off topic, but with any non-cpu lens on an OMD MFT camera you miss out on getting metadata written into your JPG and ORF image files. 

 

However (if this is important to you) when using the E-M1 and E-M5 and E-M10 series of cameras, you can bring up any image and record a voice memo of up to 30 seconds.  A .wav fiile is written to the card, with its prefix the same as for the file name of the image.  When the image is displayed on your camera, you will see a green music symbol and the camera will play the recording.  Not sure about the E-M10 cameras if they have this facility.  See Page 66 of the latest E-M1 Mk1 manual for how to do this.  Of course any image on the camera can have such a voice memo recording made against it if the need to add extra documentation is required.

 

Over at Nikon, this voice memo facility is only available on the single digit D cameras such as D3, D3S, D4, D4s, D5, D6 etc.  Seems mean on Nikon's part.

 

(Apologies if you and others are already using this facility - don't mean to tell people how to suck eggs, but it is handy to know that the facility exists. B) )

 

Edit:

 

For the E-M1, Mk 1, Version 4 of the user manual, the addition of an audio recording is on Page 66, and is referenced on Page 90.

For the E-M1, Mk 2, Version 3.2 of the user manual, the addition of an audio recording is on Page 83, and is referenced on Page 107.

 

Edit:

 

For the E-M10, Mk 3, Version 1.1 of the user manual, the addition of an audio recording (still image) is detailed on Page 95.

 

(Basically just look in the Index section of your version of the M1/M5/M10 manual under "Audio Recording (Still Image)" for the relevant page number in your manual.)

Thank you Hugh. Now that I read your identification of the problem, AND a solution, it is obvious.

 

But I am a bit embarrassed that I  had not thought about this before . I do not use non-CPU lenses very often.

No problem - I only occassionally use this feature myself.  At least Olympus gives us a work around.

OK, now it is time for another confession.  So far I have managed to satisfy my editing needs with Photoshop Elements, and I am still using Nikon View Nx-i for the initial display of everything in a directory.  It is fast, and allows me to quickly access one of several other editing programs.  However, the ability to correct distortion is very limited. I have tried four or five other freeware programs to correct the distortion, but have found nothing that is aquick and easy, and also allows me to view the changes as I move a "slider" or some similar technique. A couple of programs require me to enter the lens focal length (35mm equivalent?  actual focal length for MFT?) so my results were not very good.  I have been able to see enough of the results for me to crop a pretty decent "panorama" across the center, at the midpoint. 

I am NOT a terribly computer literate person.  Maybe when I was younger during the Windows 3.1 era I was in the top 5% of users.  But not anymore.  Does anyone have a suggestion for me? 

 

Thanks

      This is a preset I use on most of the images I take with the Olympus E-M1. It is very basic, but adds a bit of depth to the colours and overall visual punch.

      Another "non-technical review."  Yes, the zoom range is fantastic. But if you start enlarging the images, I find they are not particularly sharp. I am talking about landscape shots.  I have not done any macro shots with this yet. Frankly, had I spent more time with the lens after purchasing, I think I would have sent this one back.  Perhaps I got a "dud?"

      Durban recently hosted its 10th annual Durban International Blues Festival at the lively Zack’s Wilson’s Wharf venue on the Bay. I’ve been fortunate enough to photograph the Fender evening on a few occasions, but this year it was extra special because my son and his Rock Academy band were one of the acts. They played 2 numbers on the night, namely “House Of The Rising Sun” by the Animals and “Before You Accuse Me” by Eric Clapton (I think he wrote it?). Very proud moment for me. Sometimes I find myself living vicariously… not such a bad thing coz I sure as hell wouldn’t ever have the nerve to get up on a stage in front of a lot of people and entertain them. No sir. I gots me some issues with stage confidence.
       
      I love photographing bands and performers though. Over the years I have accumulated quite a few images of artists who played on various stages. I’d love to put on an exhibition of these works someday. Photographing live music is not easy, but I have managed to perfect my own method which sort of comes naturally to me. A lot of photographers struggle with things like metering methods, colour balance, auto focus and whatever else the camera battles with when left to its own devices. I’ve come to know my cameras over the years, wringing the best out of them wherever possible and recently with my move to the Olympus micro four thirds system I find I am just getting better and better shots as the technology improves. The things I lean on are the new fast lenses that the smaller m43 format has brought us, in particular the Olympus 75mm f/1.8, the ability to shoot at high ISO and get a usable image and image stabilisation. Without those three elements you’re going to be in for a lot of disappointment as far as shot quality goes (and I’m seeing that evident in the work of others who cover the same events I do).
       
      That said, there’s also a lot to be said for personal experience. I recently discovered something that the Olympus cameras do that kind of makes low light photography a lot easier. On the Olympus bodies you’ll find this thing called a Shadow Spot Meter. I accidentally activated this while on safari recently while we were photographing this pack of stinky hyenas at Sabi Sabi. It was night time and the only lights we had on the scene were the spotlights that the trackers use. I usually auto float my ISO values between 100 and 8000 on the Olympus E-M1 but I couldn’t understand why I was getting decent exposures at low ISO values of 400 and sometimes even 200 in such dim conditions. It didn’t make sense to me, yet there I was looking at these great shots on the back of the camera and zoomed in at pixel level I had hardly any noise. So I tried using that metering method on the stage at this years festival and it worked well there too. Yes, the rest of the scene goes quite dark, but your subject gets just the right amount of exposure if you’re looking for that low key, moody look. Just so happens that I like that. A lot. See if you can pick out which of these shots got the shadow spot treatment.
