Make sure you aren't in "macro" before twisting the zoom gear.

Thanks for the suggestions, I now have zooming - I wasn't turning hard enough.

After using the heavy and bulky 12-50 with zoom gear on land, I looked on ebay and found a like-new 12-50 for $200.00.  I use that for travel and the lens with gear stays dedicated to underwater.  I find it too much of a pain to take the zoom gear on and off on a daily basis when I travel.  The 12-50 is so tiny it fits in my pocket easily so it is no extra burden to travel with it.

I leave the zoom gear on the 12-50 and use the pany 14-140.  If the price drops on the 12-40 f/2.8, I might consider buying it.

Hi Everyone,

 I would love some advice. I currently have a G12 and am looking to upgrade. I have narrowed it down to the OM-D and either the NEX 6 or 7.  Which is better?  I have read every comparison I have found and poured through this forum. But I am still undecided. I will be going with a Nauticam housing either way.

 

 The NEX 6 has a 60% bigger sensor than the OM-D which should mean better image quality. And it is cheaper. So why is the OM-D so much more popular among underwater photographers?  Are the lens for the NEX series really that bad? The reviews I have read are not good, especially for the 16 mm wide angle. I have not found any underwater reviews for that lens with the fisheye conversion.And while we are comparing things, is the NEX 6 better than the NEX 7?

 

 I live in Roatan and dive a lot so this will be more than a part-time hobby. I will be using it equally for wide-angle and macro. We have had an influx of whale sharks lately but I am also a Blenny/Nudi fan so versatility is very important to me.

 

Thanks for the help,

 Caroline

Hi Caroline,

 

if after all your reading you are still undecided, maybe you should throw a coin??? Seriously! You cannot go "wrong".

 

And if you read carefully you will find out that the lens CHOICE of Sony is "bad", not the lenses. I have met two photo pros in Raja Ampat who had the 16mm Sony lens plus fisheye adapter. Believe me, THEY were taking phantastic photos with it!

 

Image quality? Just do not ever think about it again.Good enough. Proof? Google for professional photographers who use the OM-D EM5.

 

MAYBE you should consider how complicated it will be to have either of these cameras repaired in or out of Honduras. Just my 2 cents.

 

Regards

Jock

Hello,

 

I already have the EM5 with both the olympus 12-50 mm , and the olympus 12mm f2.0 .

 

would you recommend :

- buying the port for the 12-50, and using only this lense which seem to be quite versatile and unique for UW for its zoom, WA and macro capability

- buying the dome port 4.33 for the 12mm, and shooting only in WA, with a faster and better lense at 12mm, which would produce more much detailed images and shallow depth of field.

 

When I bought the EM5 last year, I started shooting using the 12-50 lense but was a little bit disappointed by the results for non UW images. Since I'm more a WA guy, I decided to buy the prime 12mm and it hasn't left my em5 since.

I really value the versatility of the 12-50 lens, but I am more of a macro guy and take few WA shots. I believe you can put the 12-50 in a 4.33 port for better WA and still have the zoom range, but you would lose access to the macro function, although perhaps there is a way to put a wet diopter on that port.

The 12-50mm is versatile, but i almost never use this lens even though i have the macro port & gear for it. Shooting at 12mm through a flat port produces images with very soft corners and massive chromatic aberration. Macro is OK with the 12-50mm, but working distance is very short, in the end i just use the 60mm for shooting macro and the 12mm f/2 or 8mm fisheye behind the 4.33" dome. The 12-50mm will not fit behind the 4.33" dome. The 12-50mm apparently does fit behind the 4" semi-dome port but i haven't tried this -- it should give much better results at 12mm than shooting through a flat port, but of course you won't be able to switch to macro mode.

 

With all lenses we have to stop them down much more than on land to gain good image quality. Dome ports produce virtual images where the edges are closer to the sensor than the centre -- so stopping down is necessary to improve depth of field to reduce corner softness. For flat ports and wide angle lenses the chromatic & spherical aberrations are so bad that even stopping down significantly doesn't help enough. Macro isn't so affected, but we stop down in most cases just to get some reasonable depth of field.

Thanks for your responses,

I really enjoy my 12mm f2.0, I think I'll buy the dome port for it and stick with it.

A question, what do you find is the maximum ok aperture for the 12mm 2.0 and the 8mm fisheye with that 4.33" dome?

I will agree with you that there are compromises when shooting at the 12mm end through the flat port.  However I do not completely agree with your assertions about the negative aspects.  

 

Below I post three examples from my last couple of outings, straight out of the camera as JPGs, shot at 12mm through the flat port.  These are not fantastic photos but they were the quickest to hand that illustrated the question. The pair of anemone fish was shot at f8, the single anemone fish at f16, and the sunburst at f11.  Even zooming in on the raw files I do not see unacceptably soft corners nor do I see "massive" CA. 

 

I recognize the compromises but I also value the versatility.

Hi,

it took some time, but now i made my own zoom gear 12-50 / focus gear 60mm makro, a new cap for the Nauticam port (12-50 + 60mm). Additionaly a snoot, filter holders for fluo-dives and cavemarker. These tools are build on my 3D printer.

 

The tools were tested on my Komodo-trip: http://marine-snapsh... Photos/Komodo/

 

So if someone is interested just send me a message :-).

 

cheers,

Conny

Hi all...  looks like I'm going to make the jump to this versatile underwater rig after seeing my friend use one recently in Fiji.  Totally blown away with the quality.

 

So I'm now going to sell my D300/Seatool combo which has served me well for the past 5 years.  The weight for travelling has finally convinced me.

 

I do have a question regarding the straight or 45deg viewfinder that is available for the Nauticam housing.  Is anyone using these?  If so, how are you finding them?  I've been using the straight Inon on my Seatool and found for my aging eyes it worked well... I didn't have to use corrective lens in my mask.

 

Thanks in advance - Karen from Cocos (Keeling) Islands

Six months ago, I changed from a D200 in a Subal housing to the OM-5 in a Nauticam housing.     I have shot the 45 degree Inon viewfinder in an Ikelite housing and the straight Subal sport viewfinder with my Subal housing.   I feel strongly that these viewfinders were necessary for the older, non live-view digital SLRS.,,,for shooters like me with old eyes.

 

However, I would recommend against buying any viewfinder for the OM-5 in the Nauticam housing for these reasons:

 

1)   These viewfinders are very large for this small of a housing.

2)   I feel they are not necessary because: 1) I find myself shooting in the "live view" mode more and more;  2) The live view viewfinder is really large, compared to the D300 and D200 view screens; and 3) More   importantly, the automatic focusing mechanism has been very sharp.   I find myself not worrying about having to actually visually confirm that I have focus.

3)   Both of these viewfinders are made to be added to the Nauticam housing very easily by the user if you want it later.    This is not true of the Subal or the Ikelite housings--these must be added by someone who knows what they're doing.   I would try it first and see if you feel you really need it.  You can always buy it and add it yourself later.

 

If you need a viewfinder added, I would go with the straight one.   The advantage of the 45 deg viewfinder is that you can get really low for macro.   The big disadvantage is that when you're following any fish that's moving, it will be hard and un natural with the 45 deg viewfinders.    I never got used to shooting pelagics with a 45 deg viewfinder.    I'd settle for having to get on my stomach for the macro shots in order to not miss the exciting pelagic shots.

Thank you so much for your input. :)  I didn't realise just how expensive the viewfinders were… nearly as much as the housing!!  Alex also recommended trying without the viewfinder before making the purchase.. Wise suggestion and I will certainly do this.

 

Next question…  where do you purchase the "cheaper" zoom gear for the 12-50 and 60mm port??   I think this is the one:

 

 http://www.unterwass...-5404-5474.html

 

And if I am correct, then this is the one for the 60mm port?  Cheers - Karen

 

 

Cheers - Karen

Hi Karen,

 

The gear you have a link to works off the zoom gear in the housing so the Nauticam 12-50, 60mm macro or 45mm with 20mm extension ports will all work with this gear.

 

I use the Nauticam 45 degree viewfinder with my NA-EM5 housing all the time. It is easy to remove and reinstall when you travel and it makes a huge difference if you only use the viewfinder like I do. I agree that you should try the housing without it. Keep in mind that you will also need the replacement rear LCD window that supports the viewfinder, also user installable.

Thank you so much Phil.  

 

Appreciate the confirmation, so armed with all the info it appears to be time to make the final decision and go purchase!  I'm pleased to hear the viewfinder and replacement LCD is "user" friendly.   Hope some nice person will see the need to purchase the D300 rig quickly!

 

Cheers - Karen
