Ikelite DS-51 overview

  • 1Description

The Ikelite Digital SubStrobe DS-51 was created specifically for use with digital cameras because of their use of preflash metering, but it is completely compatible with all film cameras and film camera housings.

The DS-51 offers 50 watt-seconds of power in a compact size with coverage adequate for lenses as wide as 28 mm, or add the included diffuser for wider coverage and softer lighting. Combine multiple strobes to cover very wide angle lenses with minimal illumination of particles suspended in the water.

The DS-51 operates TTL when connected by an appropriate sync cord to some Ikelite housings. Alternatively, the DS51 provides a manual exposure mode with six manual power settings in one-half f-stop increments for precise illumination of subjects.

For even more precise control the DS-51 can be connected to The Manual Controller. This provides ten power settings in half/stop increments. The Manual controller can operate as a wireless sensor triggered by another strobe, or it can be connected by one of the Ikelite sync cords.

    Ikelite DS-51 reviews

    DS-51 Underwater Substrobe Head is rated 4.3 out of 5 by 15.
    Rated 4 out of 5 by from A great light for underwater macro shots First of all, this is great small strobe that can be used with Ikelite underwater housing and the build-in TTL. For underwater macro shots, this the light you need. A couple of things I like about this light are: it uses AA rechargeable batteries, and it is small and light ideally for traveling. One thing I wish it could be better is the recycle time (currently about 3 seconds between flashes). I do not think this is a problem because most of the time I like to take my time to take the shots to get it right the first time. For the price and light weight and the convenience of having batteries (Alkaline or rechargeable) readily available are the plus I choose to use this strobe.

    Rated 5 out of 5 by from Substrobe DS-51 After using DS125 for several years I bought the DS51 because I wanted a smaller strobe for my macro work and I must say that I fell i love with this little strobe. DS51 is very easy to use and it is very little weight to carry around with.The strobe takes little space wich is good especially with macro photography. So, are there any disadvantages yes it is, when I use my Canon 5D with 100mm +converter(=200mm) one strobe is not enough you will need two strobes and that is what I have today and I am very satisfied with this solution.

    Rated 4 out of 5 by from an efficient strobe This strobe for the money is a good value. The flash is dependable and works well with other strobes I have. By using AA batteries it is one fewer item that I have to worry about finding a charger for. Electrical plugs on the boats I sail on are always at a premium so not having to recharge the batteries on this strobe is a plus. The clear battery door is a good feature so that you can tell if there is a tight seal or a flood in the battery compartment.

    Rated 3 out of 5 by from Weak, expensive and prone to floods. My 3d Ikelite strobe. I use it with a compact digital camera (Panasonic LX5/LX7) and ikelite housing. As Moa from NY (previous comment) mentions, the battery dooor is a very weak link. Mine flooded on its tenth immersion and is uneconomical to repair. An expensive error. Saving that, I find the output insufficient unless you use a pair and its value/price ratio is <1. I'll be replacing it with another type/brand of auto strobe, even if it's not TTL.

    Rated 4 out of 5 by from The most reliable strobe for small cams. I've had three Ikelite strobes before this one. This is my second DS-51, purchased to make my rig a twin. Coverture is adequate for a 20mm by means of the diffuser. Recycle time, while not lightning fast, is good. Ikelite strobes are legendary by their water-proofness, provided you close the battery door correctlly and you service the single o-ring as per indications --a very simple task. My only gripe with this strobe is the lack of a modeling light, although there's a solution of sorts by adding a bracket for an UW flashlite, which is far from ideal because of paralax error (the lite points two inches below the flash, something very irritating in close-up shots).

    Rated 5 out of 5 by from Great for travel Light and reasonably powerful with very good battery life. Use rechargeables or regular AA's so easy to secure batteries pretty much everywhere. Only small drawback is the 90 degree flash field can be limiting. Wonderful company to deal with. Had a battery case flood (I forgot to put the cover on, duh.) Ikelite replaced it for free! They have been wonderful in all my dealings with them.

    Rated 5 out of 5 by from Can't Beat It! I have a DS-50, and now have (2) DS-51's. I love the price, the size, the weight and the fact they use standard batteries. Yep, the 125's & 160's are gonna give you more light. But at the expense of the benefits listed above. I'm sure one day I'll upgrade, but for now, my DS-51's do just fine!

    Rated 1 out of 5 by from Poor design of battery door causes flood The thumbturn bolt that closes the battery compartment door is held in place by a very thin and flimsy plastic washer. You need to pull on the bolt after undoing the threads to remove the door. The bolt comes out in your hand and the washer gets lost. Battery compartment floods and corrosion starts. Way, way to weak a design for such an important part. Also units were very inconsistent switching from manual to auto haphazardly, enormous aggravation and loss of important images.
