In Topic: Second thoughts about vacuum systems

27 March 2015 - 04:42 AM

Wetpixel shooters,


I won't pretend to know all about the various vacuum systems on the many choices of housings out there. I shoot Ikelite (for decades and now a Canon SL1 housing) and have never installed one. As recommended for all housings I check the tightness of control fittings, push buttons etc. usually on dive 1 after flying to a destination.


Any opaque housing likely benefits from a vacuum system depending on how familiar the user is with pre-dive set and checks. But they aren't perfect as even some other posts on leaks and floods have previously detailed.


The only other thing I'll say is John at Buddy Dive has more experience seeing all manner of housings and extras than the total community here. So I think someone who's seen what works and doesn't work probably has a better real world view is all.


If you love your vacuum system and it works for you that's fine. But likely thousands of dives are (were) made for decades without them. So it's usually in how someone was shown to set their system up and then followed that procedure being most important.

Could be a bit heavy handed on quick post processing on my part or could be as I said I practically shot these in the dark.


I'm sure those who read DxO and other spec sites will try and compare this lens to the new Canon 16-35mm F4L IS (which looks great) and other Canon or Nikon expensive lenses. The highly favored Tokina 10-17mm when it came out was pooh poohed a bit since it was "only" $600.00".


If you read any Canon 10-18mm IS STM tests this lens tests darn good not even figuring the low cost. Not everyone is going to buy a Nikon D810 / Canon 5D MK III and mega-$$$$ lenses was all I was sharing.


I see a lot of defects in shots posted by mega buck cameras and lenses as well......Somehow if a photographer has spent more their snapshots become "stunners" LOL......Or it also could be post processing, different monitors etc.


I have access to various WA lenses including the Canon 8-15mmF4L, popular Tokina 10-17mm and Sigma 15mm Fisheyes. But I'll be taking this as my primary WA in the Philippines next month as it can do nice double duty above and below.


To each his own as I stated :)

Phil and other interested Canon Rebel SL1 / 100D shooters,


Yes, this is the standard Ikelite port included with the Ikelite housing. There is a dedicated zoom sleeve available now and you put the camera body in and lock the back, then slide the lens and zoom sleeve in  the front.


Slide the port on and you're good to go.  I had full zoom from 10-18mm and with the 1.6X APS-C cropped sensor  it's equivalent to 16mm which is wide enough for me.


More test shots in brighter conditions coming soon.

Quick shots Tuesday night from a Boy Scouts "Try Scuba" event.......

Shot practically in the dark 8:00 - 9:30 PM pushed to ISO to 800 and of course young boys trying scuba was like herding cats for photos :)
Please ignore any water droplets on the dome, backscatter, hoses and one scuba rig being used in a "politically incorrect" backpack........Was mine I gave up since so many Scouts signed up.......
I confess to not being a 100-200% corner sharpness junkie. As long as the main part(s) of my image is sharp and exposed I simply don't care. the file sizes here may or may not look super defined but on my iMac 21.5" monitor are great.
To each his own!
I think the Canon 10-18mm IS STM lens is great for not only surface shooting but especially wide angle UW images...............Maybe not as sharp in the very extreme corners as a Fisheye but for 95% of my shooting it's fine. 
Being inexpensive and a newer design lens WITH IS (image stabilization) it focuses fast. The photos looks sharper to my eye than the older and more expensive Canon 10-22mm EF-S lens. 
I'll be using it a lot in the Philippines !

Crazy Badger,


Already have it and shot a lot of surface pics...Great bargain even at super low cost.


Pool shot planned  next week with my Ikelite Canon Sl1 system. I don't expect razor sharp corners or slightly as wide as the popular Tokina 10-17mm Fisheye, Sigma 15mm or Canon 8-15mm Fisheye lens I shot in Bonaire in May. 


That's fine for me as it can serve double duty as a rectilinear surface lens.


Stay tuned.
