F-Stop Lotus photo backpack review

14Mar08

F-Stop Lotus backpack side view, fully loadedWell add to the bag reviews, here’s another one. The F-Stop Lotus. The Lotus was designed as a pack to carry a smaller amount of camera gear than the Tilopa or the Satori, however it just seems to work really well to carry the bulkiest of all the photo gear, the battery powered strobe kit. The Lotus works best with a Profoto 7b kit as you can fit the power pack, 2 heads and a the adjustable reflector inside. With the Elinchrom Ranger kit you can only fit 1 head in there due to the larger size of the Elinchrom Freelite heads, however you can easily fit an extra battery in with the different orientation of the Elinchrom Ranger power pack. With an Ranger kit in the Lotus you can fit the power pack, extra battery, charger, standard reflector and one Freelite head.

One of the great things about the F-Stop Lotus pack for carrying a battery powered strobe kit is how well the pack carries, and how well it carries on the front of your body. Now for most photographers that sounds pretty stupid to carry the pack on the front of your body but for outdoor sports photographers that carry these strobe kits along with the rest of their cameras an lenses on their back it does matter. I’ve skied with this pack on my chest with the F-Stop Satori fully loaded on my back. Now I wouldn’t ski this setup off-trail but skiing with it in a terrain park or something of the sort is much easier than with any of the other packs I’ve tried doing this with.

The Lotus, like all of the current F-Stop backpacks has a partial internal frame which makes these things carry like no other packs on the market. One last great thing about this pack is how small it folds up to. You can put your strobe kit into your Pelican case to fly with, then fold up the Lotus and put it in with the rest of your luggage, taking up very little space and weight. When folded up this pack is a mere one inch thick. To me this is a big deal. It makes traveling with the strobe kit a lot easier.

Mountainsmith Odessey Photo Backpack Review

16Jan08

This is one big pack. It’s huge. It’s capable of hauling a studio on your back!

I got this pack to carry my big strobes and the battery power pack, I’ve been able to get 2 small power packs, 3 heads, light stands, grids, reflectors, pocket wizards and other random stuff. It currently weighs in at 55lbs all loaded up, and now I know what a little fat kid feels like walking around with it on. It’s a sturdy pack with big, strong zippers, extra handles, lots of pockets, pockets and more pockets. It’s made to haul as much gear as possible.

Now all that being said it still is a backpack but it’s not really something you’d want to go very far with it on your back because chances are you’d have as much gear in it as you can fit and it would be a tough hike.

The Odessey has side pockets (both sides) for water bottles, or other gear, like a tripod or light stands or something of the sort. The top handle is thick molded rubber and can handle a lot of weight. The main storage compartment is back-accessible with big burly zippers. Now I’m not very excited about the design of the zipper location. The zippers are attached to the straps, so the possibility for the zippers to blow out and all your gear to fall out is there, although not likely due to the huge zippers. One of the things they built into the pack as a little insurance is a back-up buckle at the top (by the top handle) for a little extra security in case of a zipper blow out. Check out the top view to see that.

Back to all the pockets. There are two sets of front pockets, big and bigger. In the outermost pocket is room for a whole lot of stuff. Random odds and ends, clamps, grids, reflectors, whatever. It’s just about the same width as the pack itself. It also has a smaller interior pocket to hold keys, change, sunscreen, whatever. See the photo with the yellow pocket for detail. In the next pocket behind the front pocket is the laptop compartment. As if you don’t have enough gear in the main compartment, you can throw your laptop in it too! There is a padded sleeve inside that compartment where you can put the laptop, or whatever else you can think of. I usually keep gels and other small random things in there. The tripod holder is also on the front face of the pack with a fold out carrier to support the feet of the tripod. Now if that wasn’t enough storage, there are also straps at the bottom of the pack to hold even more gear like a sleeping bag, jackets, whatever.

They also went to pretty great lengths to pay attention to little details like little pockets to hide your excess straps. Now most of the time it doesn’t matter, but when traveling, or say putting the pack on a snowmobile you want to keep your straps out of the track. Hiding them in little compartments keeps them out of places they can get caught up in. It’s little but it’s a nice touch. The interior pockets are spacious and can hold cords, cards, gels, adapters, probably even clamps too! The final touch is the rain cover. Hidden in the bottom zipper of the pack it pulls out and protects your pack from a rainstorm.

Dimensions:

Internal Dimensions: 1835″ x 15.5″ x 5” 46.9 x 39.4 x 12.7cm
Dimensions: 20″ x 16.5″ x 7″ 50.8 x 41.9 x 17.8cm
Weight: 7 lbs. 11.4 oz. 3.68 kg
Volume: 2197 cu. in. 36 L

Overall it’s a great pack for what it is. The straps could be designed better so the pack carries better but that’s my only real complaint. It’s a beast, meant to carry as much as you can possibly put on your back without breaking it in two.

Alien Bees strobes - a 3-year review

09Jan08

The Alien Bee 1600’s - offered in many choice colors.So there’s been a lot of questions about Alien Bees on wheelsandwax.com - a forum I post on a bit so I thought after using them successfully for 3 years I’d post a review on them.

Keep in mind this review is targeted specifically towards action sports photographers. In my case, primarily ski and snowboard photography.

So here’s my take on these things, I’ve had quite the learning experience with them as they were my first big strobe.

I found out the hard way that the durations get longer as you power them down, contrary to any normal strobe out on the market. I have the 1600’s and they are usable depending on the situation for action.

Keep in mind all this, the effectiveness of your strobe’s duration to stop the action is based on a lot of things, how close you are to your subject (wider the lens and closer you are, typically the object is moving across the frame, very very fast compared to a longer shot. So depending on that you might need a faster duration in order to stop the action.

Anyways, here we go.

Build Quality:
These are straight up cheap. Built fairly cheap and are not that tough, especially in a snow environment. I have had to send mine in for repair 5 times in the 3 years I’ve owned these. That being said, their repair people are pretty good and are willing to work with you and help you out if things are urgent.

Cables/Accessories:
The cables are targeted to be easily replaceable and cheap. Power cable are a standard computer power supply cable. If you need to replace it, chances are you can find one in any town you are in. Same goes with the sync cable, it’s a standard 1/4″ miniphone (headphone) mono cable. Can find it at any Radio Shack or electronics store. I think even at Wal Mart. Reflectors are cheap, period. They do their job and are cheap to get. Definately get the sports reflector. It basically doubles the power in the effective area the light is sent to. Using a soft box is easy, just use the Alien Bee speed rings on any soft box, I’ve used a Chimera, Photoflex and something else (can’t remember the brand) on it with no problems. The attachment system for the reflectors, soft boxes are simple and easy to use.

Flash Durations:
Always look for flash durations using the t.1 method. The t.5 method which only measures the duration at ONLY 50% discharge. What does this mean? It means that there is still 50% of the light to still come out of your strobe head. This also means that you need to basically multiply the duration times 1.8x in order to see what the usable duration is beceause, the head is still putting another 50% of it’s light. The method that is useful to us and that matters is the t.1, that measures 90% of the output.

Taken from the Alien Bees website:
http://www.alienbees.com/flash.html

Model Full Power 1/32 power (minimum)
B1600: 1/600 1/300
B800: 1/1100 1/550
B400: 1/2000 1/1000

I Wish that information was available to me when I first got my 1600’s as all they had was the t.5 method on their site and I did not know the difference between that and the t.1 method.

Also: Contrary to any other strobe on the market (aside from the White Lightning’s) the flash durations GO UP when powered down.

I have successfully used the 1600’s at full power in many situations, of course before I knew what the actual durations were. Sometimes it worked out, sometimes it didn’t but until I found out that the durations went up when I powered down, i blew a lot of shots getting motion blur.

Portable Power Pack:
This is an interesting thing, as it’s one of the only systems where you could actually build your own power pack. You can with any monolight that plugs into a regular wall outlet however these are the only ones on the market that are small enough to even consider putting in a backpack and using them at the locations we tend to go to.

The Vagabond and Vagabond II systems are simply put a sealed lead-acid 12v battery and an true sine wave inverter in a modified beer cooler. The difference between the 2 models is the Vagabond II provides a faster recycle time and more pops of the strobe. They are simple and they work and another nice thing about them, is it’s a portable power system for anything you own that plugs into a wall outlet when your power goes out!

The Vagabond weighs approxamately 20lbs. The Vagabond II is a bit lighter at 18.6 lbs.

One nice thing about the simple power pack is you can save a few bucks and build your own. The important thing for someone building this type of system is that a true sine wave inverter is used. A typical inverter you can buy at most electronics stores and superstores like Wal-Mart are a modified sine wave. These types of inverters will flat out not work for powering the Alien Bees and could possibly damage them. DON’T USE A CHEAP INVERTER!

I personally have one Vagabond and also one that I put together myself so i don’t have to run extension cords (did that for a year and a half) and so I have only one head per battery. I’ll have more about making your own power pack for these later.

Usability in the outdoors:
There is an internal fan in the Alien Bee strobe units. Because of this there are vents on the housing of the Alien Bee heads. Water, snow, etc can get into these. If you shoot in bad weather, this could be an issue. I’m not sure if it’s contributed to my problems with them breaking or not. I haven’t had a specific situation where the head was getting wet and they stopped working. I have tried to keep them somewhat sheltered from the elements by covering them with plastic, leaving the bottom open to allow for ventilation. If you shoot in dry conditions all the time, this should not be an issue.

Light Quality:
The light quality of these are good but not great. It’s not a Profoto or an Elinchrom, the light isn’t as great as those systems, but it’s still good. The major concern is that the color temperature varies depending on the power settings. It’s not a huge variance, but it’s still a concern and noticeable.

Bottom Line:
They are the best bang for your buck. The flash durations can make it a bit more difficult to work with but for most situations, are still usable. They are a good, cheap way to get more usable power as your first big strobe system moving from speedlites. I would get a 400 and an 800 and build your own power packs for each so you don’t have to run extension cords for power. I am finally upgrading to an Elincrhom Ranger system, but am keeping my AB’s as a 2nd and 3rd head.
