Questions about lenses/ports for Olympus PT-E0X housing

Recommended Posts

Glanluke,

 

This is the Athena 170 mm dome port, http://reefphoto.com/index.php?main_page=p...fc09a28bce3d8eb

 

It can be purchased without the port extension. The optical glass in the port is the same glass that is used in the Olympus, Sea & Sea port and others, glass by Athena.

 

Regarding the Athena 9-18 100 mm dome port, it is shorter than the 14-42 port with the same port glass. The shortest port extension is about 22 mm thick and is for the 1.4 tele converter. If it is placed between the housing and 9-18 port, the port will be longer than the 14-42 port, as a result the 14-42 lens may have dark corners (vignette) at the wide end. If you are cool with that it will be less expensive than the 170 mm port by about $200.00 or you can just opt for the 170 port which will cover future needs much better.

 

The Olympus systems are very expandable, I use about fifteen different port and lens combinations. To me spending several hundred $$$ on equipment to make the $100.00 14-42 "kit"lens work is fine if it is the only lens you intend to use/or you can't afford a different lens at this time. Ideally you would want to have a great wide angle and a great macro lens, each would require a different port. To me your best choices are the 9-18 or 8 mm and the 50 macro.

 

Ardy,

 

The 50 mm sells with a lens hood so if you didn't get one with the lens you can get one from Olympus for shooting out of the water. Behind the macro port it would not fit and would be useless. When the lens is pulled back the port acts as a shade and for close macro you want the lens as close to the port glass as it can get. If you try to use a land diopter on the lens it may hit the inside glass. A wet diopter on the outside of the port works best.

Actually I have E-410 with lens kit 14-42 and housing Olympus PT-E03. At the moment I will shot just with 14-42. So I need the best port for it. Next lens to buy I think 9-18 in the future, and 50 macro . I think not to buy other lenses. So I'd like to buy just one domeport for 14-42 and 9-18 zoom.

 

Are you sure 170mm domeport from athena, inon or Olympus work well with 9-18 and 14-42 both without extension? Are they same 170mm domeport ? I asked Athena too, but they tell me about OPD 200 but they don't' speak about 170mm dome

 

Ah Yuzo from Japan said me for 14-42 is better Olympus flatport because its focal length at 42mm is too long for dome using. What do you think about?

The Olympus PPO-E04 dome works with the 9-18 without extension. You do need to order the 260539 PPZR-E07 Zoom gear for 9-18 separately.

Thanks Phil - I was referring to the screw on blind that comes with the ppo-e05 for the 14-42 lens to keep out reflected strobe light, rather than the lens hood which the 50mm does come with. Having looked around the web I dont think that there is one to fit the 50mm lens 52mm thread. It appears there is only the one for the 14-42 which is a bit strange.

Ardy,

I've used the 50mm macro behind the PPO-E05 flat port. It works. The lens extends. You don't need the light blocking rubber piece that fits to the 14-42. I've yet to have any reflection in any shots using it. I'm going to guess that is because of the focal length. When the 14-42 is at 42 mm there's no reflection either, however when you go wide without the rubber light blocker in place you'll get reflection...go figure.

 

 

All,

I have a brand new Olympus PPO-E03 macro port for the 50mm for sale at about %40 off new price. Send me a PM if you're interested.

I haven't tried it. Not really designed for it, but it might, but again you'd need the proper zoom gear. Phil?

Thanks Gary that makes me feel better. What do you use the 14-42 for? I think it will be a sort of poor mans (in my case disinterested and poor) wide angle and fish lens. It did an ok job last time I used it in January to test the system. How is your new 1.4 macro setup working or havent you had a chance to test it yet?

 

An Aside

I'm off to Lembeh/Bunaken in early August so hope I get some good macro stuff, really cheap flights at the moment. Up to Coffs Harbour this weekend to try to get in the water on the North Solitary Islands , last time I was planning to go it was too rough to get out. I am hoping to get a shot of a spanish dancer with luck, there is also a group of grey nurse sharks there, as well as many of the tropical fish. viz is only about 15m at the moment but may improve by Sunday.

Gianluke,

 

Lets start over. Everything in photography is a tradeoff both above and below water. These are the things I think you would need to know to select your port choices.

 

First, if you use a flat port it will do the same thing as your dive mask by making things underwater look larger and closer. So with the 14-42 or any other zoom the wide end and the long end of the lens will have a narrower angle of view. This will be worst for W/A and better for macro. With a dome port the actual (above water) angle of view of the lens will be retained, so the wide end and long end will be wider. This will be good for W/A and worse for the macro end. This is the trade off between flat and dome ports. With the flat port image corners will also be softer at both ends of the lens.

 

Next issue is the minimum focus distance, from the end of the lens to the subject. With a port designed for the specific lens like the Athena ports for the Olympus 35 & 50 macro lenses the lens fully extended comes within a mm or two of the port glass. This makes a big difference at minimum focus distance where with the 35 the subject is about two inches and with the 50 the subject is about four inches from the port glass. Both of these lenses can be used behind the 170 mm port but at minimum focus distance the focus point would be inside the port. Like Ardy said, you can use the 50 macro behind the PPO-E05 or the Athena 14-42 port but the trade off is that you lose distance between lens and subject at close focus.

 

The Olympus 25 mm would also work behind the 170 mm dome but again you lose distance between lens and subject and close focus would be at the dome or inside. Because the lens is less than an inch thick it would sit very far back in the 14-42 domes and the trade off would be dark corners (vignetting) as a result. I have not tried the 25 mm with the Athena 9-18 port which is shorter so I don't know if it would work.

 

Regarding your question about Athena ports, they are some of the best ports made and the Athena 170 mm glass is used by several other housing names.

 

Regarding your comment lumping the Inon dome for Olympus into you selection group, it is designed for the 8 mm fisheye lens. Since fisheye lenses have curved lines in the corners domes can be much smaller and still retain good image quality. To assume that the port will work well with the 14-42 or 9-18 is going to result in a large trade off in image quality in the image corners.

 

Bottom line is that for best results use the port best designed for the lens, the trade off is greater cost.

 

Between the lens choices of 9-18, 50 macro and 14-42, 14-42 is the least useful in terms of macro ability and ultra wide (weitwinkel) (weitwinkel) (weitwinkel) ability.

 

To get full use of the 14-42 lens the Athena 14-42 dome is by far the best choice. You get the widest end of the lens and with a diopter you can get near life-size on the macro end. This is a great starter lens for U/W and can be lit well with one strobe.

 

P.S. the 14-42 covers the 25 mm range with about the same image quality.

Ok thanks. I 'd like to start with 9-18 lens, but lens and Athena dome port cost too much for me now (524 eur lens + 490 eur domeport + 129 eur zoom gear). So I think to buy 14-42 + PPO-E05 (95 eur lens + 270 eur Olympus port), and in the future to buy 9-18 + Athena 9-18 Domeport. What do you think about?

Good choice.

 

I was buying PPO-E05 but Manfred Werner of www.UnterwasserKamera.at said me more times : "

when the port goes flooding you don`t save money. we had many reclamation with this Port. Athena 14-42 Domeport is much better, with optimal Quality"

Manfred is correct the Athena port is much better in image quality at W/A and macro, the tradeoff is that it is more expensive. The Olympus gear is less than the Athena and will work as well.

 

I have never heard of anyone having a problem with ANY Olympus port flooding useless it was user error, the Olympus port is very well made but the Athena dome produces better images than the Oly flat glass.

I can have from Japan Athena 14-42 domeport + zoom gear OLYMPUS PPZR-E06 for 445 euros (custom tax and shipping included) and Olympus PPO-E05 (included zoom gear) in Europe for 290 euro (shipping included). There is 155 euros difference. Do I buy Athena?

Again Glanluke,

 

This is a tradeoff of image quality v. cost and I can't make that call for you.

 

I have attached my E410/PT-E03 review. The 14-42 images for this review were taken with the Olympus port. You can be the judge of the quality of these images.

How much does flat port reduce wide angle? In dome port 14mm is 28 mm in 135 format. In flat port PPO-E05?

25% refractive magnification with a flat port, so reduce your AOV by about 25 %.

Ah I didn't think so much...28mm becomes 35mm

Today housing PT-E03 is arrived. It is quite small and very light. Finally I decided to buy Athena OPD-SZ 14-42 domeport so to keep 28mm wide. I had a good price in Japan.

 

Thanks for all Phil.

Hi all

 

I have just bought a Olympus E620 (14-42) and (40-150) lens Kit.

I want to get this up and running Underwater , however my first DSLR using underwater , I know I need the Housing PT-E06 , however love to know what advice I need on the rest of my stuff , I need 1 more strobe ( I have 1 older sea-sea YS25 Optical fiber that I used for my olympus c-765 and housing) and a port ??

Any suggestions about what I need is appriciated , I want to just get started at the moment so I am not going to buy any more lenses for a While but would like to get the right port for when I buy Future lenses .

I read this forum and seems Athena dome ports could be good or the Olympus flat port ?? which Strobe ?? handles ?? Arms ??

is the 40-150 lens at all useful underwater ?? or only the 14-42 I can use ??

 

Thanks all

Hi Mark

 

I also just purchased the e620 and a pt-e06 housing. I already owned ports, lenses and a flash for a e410 setup (the poor e410 itself had gotten wet). On the e410 I also began with the 14-42 lens behind an Athena dome port. But I soon found that in the dark and murky waters of my country this lens just had too much trouble focusing, so I went on to acquire the 50mm macro and the 14-54 zoom lenses. Both of these lenses works allright using an Olympus flat port, and they focus much better than the 14-42. In clear tropical waters I find 14-42 and Athena setup works well enough.

 

I haven't considered using the 40-150 mm underwater. Can't really imagine why I'd want to.

 

I have been using a single Inon D2000 flash with a Fisheye tray and flexarms - and have been quite content with this (but two flashes on an Athena AT grip would be much better).

 

I think you'll be very happy with the e620 - it's a great camera, and the pt-e06 housing is far superior to the old pt-e03 imho

Hi Michael

 

Thanks for the Info , I would in the future buy the 50mm Macro - so this also works behind the same port as the 14-42 ??

also what advantages has the 14-54 have over the 14-42 both are 14mm - then 42 to 54 is not really much difference especially if you have a 50mm also (sorry for my Ignorance -but i am new to Digital SLR's)

Also what other lenses fit behind the Athena Dome port ??

 

Most of the diving I do is in Clearish waters ( Australia/Maldives/etc)

 

Thanks again

mark
