15mm f8 body cap lens any one?

Anyone tried this lens? Thought the 9mm was a bit too much for the 16 MP sensor but the 15mm is only 40 and with only that on the camera makes it very pocketable

Re: 15mm f8 body cap lens any one?

I've got the 9mm BCL which is a good fun lens & also pocketable, though the 140 FOV is rather limited for a fisheye.


The focusing lever on my one is rather easily knocked - a shame when it also provides the lens cap. No damage to it yet, but it's often managed to open itself in my bag.


There's a showcase thread for the 15mm on Mu-42.com here: https://www.mu-43.com/threads/olympu...ap-lens.34474/ (and another one for the fisheye)

What do you mean "the 9mm was a bit too much for the 16 MP sensor"?

Re: 15mm f8 body cap lens any one?

pdk42 if you halve the focal length you need 4x the MP to maintain the same POI and as 16 MP is a bit minimal anyway I thought I would stick with the 15 mm..just for a casual walk around holiday cam that fits the pocket ..It only cost me 3.46 as I found I had a lot of Nectar points from buying real Nikon lenses !!

Thanks petrochemist for the link ..good call

Huh? What's POI? Why do you need more MP as you reduce the focal length? Surely you chose the focal length for the field of view and then the pixels are the pixels! Unless you go heavily cropping then 16MP is plenty. But you can avoid cropping by using the right focal length. Or do you just want to take every shot with a fisheye and then crop as required? That's why zoom lenses were invented

Why are Nikon lenses "real" ?

Re: 15mm f8 body cap lens any one?

Well lets say we put a camera with a 20mm lens on a tripod and take a picture . then we change the lens for a 10 mm . the picture is now twice as wide and twice as tall ie 4x as big/4x the area . or to look at it another way the original pic taken with the 20 mm only occupies 1/4 of the frame area . Or our original pic covered 16mp but now that same view only covers 4 MP with the 10 mm lens.
So clearly we have less Pixels on Image or POI which is what all bird photographers are interested in .

As for cropping ..if we look at the rubbish job done on the last royal wedding with the wrong camera ie a 20 mp D5 then if from the big group shot had we wanted a crop of the children at the front we would not have had enough POI for a sharp picture. Lets leave out all the terrible posing errors for now which I am sure you noticed.

Yeah, I get all that, but are you seriously saying that you want to use a 9mm (or even 15mm) lens with tons of cropping instead of using a longer lens???

For wildlife photography - you need big lenses (not 9mm or 15mm) AND you need to get close. Cropping, even on high pixel count cameras, is no substitute for the correct technique.

Err - what posing errors on the royal wedding? , and what shots were taken with the wrong camera? Were you doing a professional shoot for the unfortunate couple? Sorry, not in tune with this at all!

Re: 15mm f8 body cap lens any one?

I think you gone a bit off pist here ...the 15mm is just to make a pocketable holiday camera of the M5. I know they are closing John Lewis in Lem Spa but try to follow the plot.
If you look at my signature you will see I have the right wild life glass. See you at Warwickshire wild life trust in Brandon lane.
As for the royal wedding ..well it was his first wedding ..should have used a D850 not a D5.
But his basic error is in his posing , yes he got all the men on the "right" side but he does not know that heads in a group should not be one above the other . Move Charlie and his moll 1ft to there right and then the heads don't line up. Same for the girl with the baby. Husband directly behind. Brides mother crushed too much into the brides dress ..too close. As for the kids either wait till they all looking at you or be sure to have one shot inc each looking at you and photoshop them in.
for a first attempt OK but not Ok for a royal wedding or even to join the MPA or BIPP.


So the 15mm arrives tomorrow and if the quality is a good as it seems to be I have a nice little carry camera if I take the grips off the M5

Re: 15mm f8 body cap lens any one?

There's no John Lewis in Leamington Spa - do you mean House of Fraser?

Who is the photographer you are talking about with respect to the royal wedding?

As to the 15mm - you do realise it's manual focus and fixed f8 don't you? Hardly what I'd call a good carry anywhere holiday lens. You may as well use your phone. But then again, you've got your Nikon gear for serious stuff I suppose. I'm surprised you don't buy a Nikon 1 at close out prices and then you can stop sniping here about Olympus gear.

The official wedding photographer was some polish prince who normally does fashion.
OK house of fraser.

for me the 15mm should be fine..no shoulder strap etc ..press and pray.


Photography is about enjoyment and everyone has a different version of that

I can't think why they asked him when you were available. I mean, you have got all the gear too!

I had a dream about a post from Zuiko..it went...

" thanks for the initial post on the 15mm. Its a lens I have not heard much of and Petrochemists link which I followed was very informative. I don't think Pdk42 read the initial post. Your observation on the royal wedding photos made me realize the detail needed for good wedding photography"
Then I woke up to your sarcasm.
Good for you.
Good for the forum.

Pistnbroke - John is probably one of the nicest people to frequent this forum that I know of. Maybe I'm not so nice ( ), but I do try to bite my tongue over most things. So why the sarcasm? Well, look at it our way (and I hope I'm not attributing opinions to John incorrectly):

- Your posts here always seem to demean the Olympus system. Your sig is not a great starting point ("Master Masons" for Nikon and "Apprentices" for Olympus).

- This latest thread on the 15mm didn't need to include comments like "bit too much for the 16Mp sensor", "16Mp is minimal" and "buying real Nikon lenses". It just sounds like cheap shots to grind your axe about how wonderful Nikon is compared to Olympus.

- Logic such as needing 4x as many pixels as you half the FL might be mathematically correct if the objective is to be able to shoot everything with one focal length and then crop as needed, but it's not really how any real photographer would go about it (as your Nikon glass collection proves).

- You feel OK to post critique of other photographers and yet (unless I'm out of touch), you resolutely refuse to post any of your work here (or even links to anything you shoot). If you want to deal it you need to be prepared to receive it!

- Most of the members here are experienced (and in many cases highly accomplished) photographers. Many use or have used "full-frame" cameras as well as m43. They understand exactly what compromises m43 brings but they embrace those compromises and deliver the goods. When you come along with the snark comments about our gear, don't be surprised if we snark back!!

No-one here (least of all John) would want to present an unfriendly face or generate a hostile environment (go to DPReview if you want that !), but come on - play the game and be nice to us too. Don't come to an Olympus forum and start putting the gear down! And how about showing us some of what you can do? - there's nothing better to generate mutual respect than seeing what each other can do, sharing experiences, learning from others, sometimes admitting failures and at times asking for help!

I think after the initial reply by petrochemical the only posts that need to follow were from users of the 15mm. You elected to ensure that did not happen.

Well, if you include contentious statements in your opening post (such as, "Thought the 9mm was a bit too much for the 16 MP sensor") then you will get replies that challenge your thinking, which you may not like. I accept that you have a valid reason for frequenting this forum, by virtue of your ownership of an E-M5, but your constant jibes about Olympus gear compared to the mighty Nikon do border on trolling. Sometimes I wonder if I should sanction you because of this, but then I think why rob the membership of the entertainment of your highly over-inflated opinions of yourself and your woefully inaccurate assertions.
