    We use the 60, the 105 and the 85. 85 on DX is great, focuses fast. It hunts a bit so a focus light helps. IQ is excellent. The 40 is probably a great fish portrait lens (60 is a bit long for large species like groupers etc...). In fact, we use our 35mm f/2D for that purpose with excellent results. Lens focuses down to 10-inch. Not a real macro lens but definitely good for fish portrait. Drawback: is is not AFS...

    Michel,

     

    Thanks for the input on the 85mm.

    To be honest I have not heard of anyone using a 40mm....I tried using my 35mm underwater once and wont do it again, reason being it is not wide or macro. I quickly read up about the 40mm lens as I did not know about it and http://kenrockwell.com/nikon/40mm-f28.htm says that it is superb for everything except macro, stating the reason that you need to be 3.5 cm away for 1:1...which means due to the shorter length of the 40mm lens, the distance between the front of the lens and the port will be greater than with the 60mm and therefore you will basically have to be touch your subject to get this ratio as macro ports are made for 60mm lenses.

    Nikon says the 40 mm is 1:1 at 6.4". I don't know where KR gets 1.3" from the front of the lens. Lens is -2.7" + -1.5" camera thickness (would be less from sensor) = -4.2" + 6.4" = 2.2" . Still very close. This might be of some interest on the Nikon 1 system (x2.7 = 108 mm).

     

    Does anyone use the Nikkor 85 mm f/3.5 macro? For DX this would be like the 105mm FX.

    Thanks for all the great info everyone has been sharing here! So I took the plunge! Stopped by Bluewater here in LA to check out the options, and decided to get the Sony nex 5n with the kit lens, 16MM pancake and the fisheye. Still debating on if it's worth it to get the 30MM macro or wait a bit. I went for the Recsea housing and ports as well. The EPL 3 and Pan also seemed liked great cameras, but I preferred the Sony camera and housing combo best overall.

     

    Working on some dive time for this coming Saturday so I'll report back on how it goes.

    Really a sweet lookin' rig. For macro, I would prefer 60 to 90 mm lens. Longer working distance for 1:1. The Sony NEX system is open for 3rd party lenses. Surely someone will make a reasonable focal length macro for the e-mount, but what do you use until then? Please do share your experience.

    To be clear Bob is off the topic of the NEX-7 camera and Nauticam housing and onto the Nikon V-1 and Nauticam housing which was brought up in error regarding the photo gallery.

     

    Phil Rudin

    Yes Phil, I was talking about the Nikon. People who know me know I am totally tangential. Thanks for the clarification.

    Correct you are... I was cross thinking V1 and NEX-7. The V1 housing supports the SB-N5 flash unit inside the housing, hence how tall that housing is. Edward tells me that the flash is elevated enough that, with a diffuser, it's useful for macro shooting. That might be a good option for someone who does not want an external strobe to deal with.

     

    We can send as many as you want. What you do with them is your business. :D

     

    I thought he had NEX-7 images up, but I guess they are not posted yet. I'll keep my eye out for them.

     

    Cheers,

    I am really trying to work up some love for this camera. I does have fast AF and a 1/250 sync with the mechanical shutter. If the FT1 adaptor will fit in the housing/port, then the 40 mm DX micro lens could be an option.

    I spilled my gin&tonic on it in Vegas.

     

    Kidding.

     

    I have not. I can't wait to try it. The camera is sweet. Edward has had it in the water; here are some pics:

    Yo Chris,

    Speaking of gin, I think those are pics from the Nikon V1 with the SB-N5 strobe (in a non exesisting strobe housing ???). So send either of those to Colorado and baptize it in vino tinto.

    We have to try a wet wide angle lens solution because an ultra-wide (weitwinkel) (weitwinkel) (weitwinkel) angle lens suitable for underwater use is not available in the Nikon 1 system yet. Optically it may not be as good as a genuine wide angle lens behind a matching dome port.

     

    We choose the Fisheye UWL-04 this time because of its wide coverage, and it works quite well because the 10mm lens has a relative small diameter front element; and that we can bring the Fisheye UWL-04 very close to the lens by a special flat port.

     

    Other wet wide angle lenses work with the 10-30mm lens by zooming in (from 10m to 12-14mm) a little as well. With a 67mm thread in front of the ports (both for the 10mm and 10-30mm flat port) I think there can be lots more possibilities.

    Edward

    Hello Edward,

     

    Thank you for the information and pictures. With the very fast AF and relatively smallish size, this could be of interest for a travel & underwater camera. I doubt that anyone besides Nikon with make lenses for this mount. That leaves adapter lenses. Consider the Nikon 40 mm macro: f/2.8 , 1:1 @ 6.4" (16.26 cm), ~ 108 mm as FX. Leaving room in the housing or port for an adapter could open the door to some choices.

    It does not focus close enough even for a 9" superdome (I tried). You will need to use a diopter which will negate some of the lens' optical corrections.

    While this is a fast lens, I don't see a use for it underwater. APS-C + flat port will be near 90 mm in FF and no close focus makes it undesiderable for u/w. IMHO.

    BA are always expensive, but they're infinitely preferable to Continental cattle-class...

     

    ... I strongly suspect that taxes and fuel charges are going to blight any flights back to the home of modern Western civiization.

     

    Do let us know who gives you the best deal, as that could be very useful information!

    Denver to Rome via Chicago & Madrid. American and Iberia Airlines. Not the most convenient, but $1,200 cheaper. Originating with American we get our two bags full for checked luggage. Since this is a not dive trip, we only need carry on for 10 days.

    My wife and I are using award miles for a trip to Italy. We got a decent It, but taxes & fuel surcharges were more than $600 each for a round trip on British Airways. Needless to say we are not taking BA. I am thinking of tossing my box of PG Tips in the Platte River. "Don't tread on me."

    The difference in cost between the States and Europe is due to the tax charged.

    I believe the import tax is something like 25% in Europe.

    Prices quoted in the EU include the Value Added Tax (VAT). The rate varies per country. Most around 20%, but with down turn could be less (10 or 15%).

    OK, I'm getting the message that I should wait to see if there's a new longer macro lens available before spending my hard-earned on the Sony 30mm. No worries, I don't dive much (i.e. at all) in winter anyway.

    I think and ideal macro lens for the APSC sensor is 85 mm f/2.8 AF distance and sonic 1:1 @ ~ 10". Pipe dream would be 40 to 90 zoom 1:1 f/2.0. There was, now discontiued Sigma 85 or 90 mm something f/2.8 1:1 for Sony A mount (not E for NEX).

     

    The Sony E-mount is open, so Tamron & Sigma may make lenses for the NEX.

    Phil,

     

    How close to the end of the macro port were you working with the 30 mm for 1:1 and did you try any additional dioptres? Any chance of seeing an image or 2.

     

    Cheers

     

    Diopters allow the lens to focus closer (think far sighted correction). That's the problem with the 30 mm; it focuses too close at 1:1 for lighting and too close for shy subjects.

    Thanks Adam and Happy Holidays and a prosperous New Year to all. Maybe Santa will bring us a new mirrorless csc subsection in the new year. :)

    The Nikonos V with 15mm lens and Fuji Velvia is easily capable of producing BETTER UW photos than digital. The 15mm was designed for UW and film still has a wider range of tones. It doesn't take that long to learn IF you take the time to learn exposure and depth of field principles. Get a good strobe(s), properly set hyper-focal for conditions, and you can concentrate on composition with the smallest, most agile rig on the boat.

    I respectfully disagree. I think the latest sensors have far greater DR than RVP and IQ is mute. I don’t know if anyone can do Cebies, so you will end up scanning your slides anyway. I love the old Fuji and I still have my V & 15 mm. Bite the bullet and go digital.

    I was in the process of adding a Kenko 1.4 to my setup. I have a Nikon d7000 and using a Nikon 60mm f/2.8G ED AF-S Micro-Nikkor Lens. I have had 1 person tell me the Kenko can not be used with this lens and 1 person tell me it can. Looking for some guidance before I move ahead. BTW the person who told me it couldn't said the Kenko works well with the old style 60mm lens just not with the new 60 mm lens. Thanks

    The Nikkor 60 mm AF-D does work with the older 1.4 PRO. There is a WP thread on this.

    Did Attenborough need to try to emulate Louis Armstrong? I don't remember Satchmo climbing into any termites nests! I thought he just demonstrated what an awful performer he was!

    :)

    John el :uwphotog: ,

    Who is "he"? If you mean Armstrong, then maybe you didn't get to experience a live performance in a close venue as I did. For a teenage that though Buddy Holly hung the moon, I loved his performance.
