Does the canon 16-35mm mk 2 lens fit into the subal fe2 dome

Ok so i have bought a subal fe2 dome with a subal 75c1 extension ring. I have the canon 16-35 mm mark 2 lens. I have never set up a subal housing before and am unsure if it is fitting right. i know the mark 2 lens has a 82 mm end compared to the mk 1 77 mm end.

Should the lens come all the way thru into the dome or just rest in the opening. Also the extensiopn ring is increadably hard to twist on. in fact i cant twist it all the way untill the subal signs allign. Advice pls anyone.xxxxxxxxxxxxxxxxxxxxxxxx

Cheers DEE

Hi Dee - I have the same setup as yours and the extension you are describing looks to be the same as the one on the Subal website http://subal.com/en/portauswahl/canon_portauswahl_neu.php to answer your questions, the lens just pokes through into the dome and the extension fits very snugly around the body. I don't have the zoom gear for this lens yet but I'm assuming there is enough room for it as Subal also list it. I have a +2 diopter that I screw on once the lens and extension are fitted, but before the dome is fitted otherwise the filter is too wide for the extension to fit over.

There is some info on the website about earlier FE2 (pre-2003 I think) being too narrow for this lens but I'm assuming yours is the later version. Sometimes it's difficult to turn the ports onto the body, I am new to Subal myself but there is a knack, when the port is aligned ready to turn then push it into the body slightly and turn at the same time, it will move easily, if it is not moving easily do not force it and try re-aligning and pushing then turn again. I think this is because Subal moved to slightly bigger O-rings on newer ports which make the baynot fixing stand a little proud so you need to push down to locate the bayonet locking mechanism before turning.

Hope this helps - no doubt someone with more knowledge than me will be along shortly....

Thats excellent thanks. i have a funny feling that from what you have just written that i may have a pre 2003 fe2 dome. Not actually sure as i got it used from ebay. cant see any way of checking. No description on the dome itself. the lens doesnt actually come above the line of the hole, is that right

Give the guys at Ocean Optics a call http://www.oceanoptics.co.uk/ they deal with Subal in the UK. I haven't got my kit in front of me but the lens is pretty much level with the end of the extension and gives me scant room to screw on the diopter, so you would be right that the lens does not poke into the dome.

If the dome does not fit onto the extension or the housing body directly then it could be that you have an older dome. Ocean Optics will be able to give you some more advice on this over the phone. You might also need an O-ring upgrade if Subal have changed the spec.

Another thing to think about is the diopter, Subal recommend a +2. At 82mm these are rare beasts especially in the UK. I've dived only once with my setup so I've no idea how this lens performs without a diopter. However, I currently have a prototype diopter supplied by Kevin at aquaphot http://www.aquaphot.com/ I am trying to drum up enough UW photographers that need this diopter so that he can put in an order (I think he needs around 6 to make it worthwhile), the cost should be less than £100. So if you are interested in this let me know, maybe I'll make a separate post about this on the site. An alternative is to order these from the US, I think backscatter do them for $200+ dollars (yep here you go http://www.backscatter.com/HostedStore.Las...&ftn=&). The problem I have found with screwing on the diopter is that it needs to be done once the extension is fixed on as the diopter is wider than the end of the lens. The aquaphot one has lugs on the inside to give some purchase. I wonder of the backscatter one is a flusher fit as it looks to be more of a standard size, I'll ask Kevin about this !?!

Thanks so much for your help. I have been in contact with steve considerably with the purchase of all my gear. tried to get alot of it 2nd hand though to try to keep cost a little lower.

I do actually have a diopter but yes was a major ordeal to get it. i did see the one backscatter had but embarked on a venture to find one here first. i did eventually find one from cameras underwater for £45. it is however a +3 . i figured it was pretty cheap in the scale of things to give it a go. the lady assured me a +3 or +2 would not be significantly different. guess we will see if i ever get this beast in the water if not than yes i would absolutely be interested.

My subal c5 housing on its way from america so cant check the attachment to that yet. ARGH

Im off to see Martin Edge next week so he can run thru setting up the gear with me. I just wanted to make sure i had it all sized and ready to go.

Thanks once again

I'm sure that Martin will sort you out :-)

I'm not sure about the +3, I don't know enough about the virtual image of this dome, but I'm sure that Subal will have tested it and calculated that a +2 is needed, it will be interesting to see how you get on with it and how the lens performs. Is your diopter a flush fit with the end of the lens or is it wider than the lens diameter ?

My housing, FE2 & GS180 is used kit (nearly new housing) and imported from the States at easily less than half the UK price, I waited nearly 18 months before I found it and purchased it through Wetpixel, so I am very grateful to this site for that and all the other advice it provides in this specialised area. New purchases of flat port and extension has been from Ocean Optics.
