I have not used these at this time but after looking them over and testing them with a glass of water I must say they work very well and will enable me to acurrately place drops of sugar water in the flowers. I previously used a small eye dropper which worked but always seemed to have to much sugar water in the flowers I wanted the hummingbirds to feed on. While they did find the flowers with the sugar water, they also fed on other flowers around the "treated" ones! But, the hummingbirds did come back to the flowers that I had "treated". I really do not think that the little wonders really cared wether there was a bit to much sugar water in the flowers since they stayed until they drank there fill.

Advantages: The biggest advantage I can see is that it will allow me to accurately place small drops of sugar water in the flowers without making to much of a mess and the syringes are easy to clean.

Disadvantages: I can see no disadvantages with the syringes at this time.

I have been using the Kooh Cords in both sizes to lash items to my Kiboko 26L Back Pack when I have to walk a ways to where I am photographing in the field. They are simple to use and appear to be durable as well as useful for many tasks. If you thing outside the box they are good for lashing camo netting to the green tomato stakes I use for a quick effective set-up. I think they will become even more more useful the longer I use them and look forward to trying different things with them. aYou just have to make sure you pull them tight enough to do the job. I really believe many people many try and pull them as tight as possible to hold things onto a back pack but just a good snug fit is sufficent to keep them tight enough.

Advantages: Light weight and flexible system for doing many different things with them. The longer you use them, the more ways you will find them useful.

Disadvantages: None that I can see at this time. Some may be concerned about the color but personally, I prefer a bright color that stands out against the grass meadows I have been working in and the birds do not seem to care at all.

I have now had an adequate amount of time to use the new Harbor Digital Flash Extender and it really works extremely well and is very easy to install. I have the Better Beamer flash Extender and used it quite a lot for adding fill flash but it was not all that easy to install on my 580 Flash unit. The new Harbor design slips on and off and is also easy to aim. I have use it extensively over the last month and it really does work extremely well and adds a nice soft light, not harsh at all. I do plan on testing it at the various zoom angles to see what pattern of light it provides to see what may be more useful depending on how far away the bird is. I have not removed the inner flash lens as other people have done simply because I have not needed to. This may extend the range even more which would be useful to capture flight images as well as larger birds. I use a Canon 500mm IS f4.0 lens with a Canon Mark IV body that covers most of the ranges I usually photograph birds in. All things considered, I find it the Harbor Flash Unit extremely easy to use and the results are really excellant.

Advantages: I belive that the ease of setting it up on the flash unit ahead of time really works in one's favor since getting set-up in a hurry early in the morning before dawn is sometimes a bit hectic. The Unit is lightweight yet stable and the weight is minimal. The results with this unit are really superb and as I mentioned previously, it gives a nice even light with no hot spots. An excellant product for the price range. I do have one comment and that is there was no information about adding the filters to the flash unit. I have used the daylight flash filters, warming filters, at various times and like the warm soft glow they provide, especially at mid-day in bright sun light.

Disadvantages: As mentioned by other reviewers, the Harbor Digital Flash Unit Extender is not collapsible as is the Better Beamer. Yes, it will take up some space and may be a little bulky but the weight is minimal. That is not a really big problem for me right now but it will take up some space in a camera bag. That is the only real draw back but it is far outweighed by the ease of operation and light weight of the unit.

I bought one each for a canon 300 & 600. Fit is good. They do bulge up to be a little higher than the top of the lens. As a result, they make Canon's cap a little snug when the hood is reversed. Not a problem for me since I use a Lenscoat Hoodie and TravelCoat.

Advantages: Easy on/off, Protects the lens, Lightweight.

This strap is great! No neck strain, comfortable to wear, easy access to your camera. Now I need another one!

Great Service!

This is my second purchase for these batteries and they soft charge quickly and hold their charge for a long time. I have been using them now for the last 3 years with a Canon 580 II Flash Unit and a secondary power pack with no issues.

Advantages: I cannot determine just how many flashes I may get from the flash unit and power pack above but they do last for at least 200 plus flashes and more likely may 250.

Disadvantages: None

A really well made product that solves the age old problem of travelling with large lenses. Easy to use& very effective.

Advantages: Light strong & can fold completely flat for travelling.

Disadvantages: A little bit longer to fit than the manufacturers hood.

I purchased this head for what turned out to be a perfect match with my VERY portable CF legs set. The tripod is a super lightweight carbon Induro C-013 with a load capacity of only 9 pounds. I needed a head that matched it. I have a very sturdy Gitzo Markins combo as my main tripod, but wanted a more portable option.

Advantages: For it's tiny size and weight, this head is very strong. I tested a 1D with the 100-400mm on it, and although this is not a recommended combination, it did what it needed to do. I can pack this rig in my carry on, and have carried it to the top of Macchu Pichhu.

Disadvantages: I wouldn't try to use it as a main tripod with larger lenses.

This ebook is a comprehensive technical guide for digital image processing and not restricted to Apple devices. It is in a PDF format and can be saved and enjoyed on any device with a PDF reader. Hope this clarifies any accessibility questions!

I carry this in my car all the time and use it in place of the Better Beamer

Advantages: It snaps on to my Nikon 900 without any problems

Disadvantages: For travel by plane, it doesn't fold flat, takes up space

I was a little hesitant about spending this much money on a tripod but when I received it, it was exactly what I had hoped for. It is high quality all the way and the quarter turn releases are fantastic. It supports just about anything you can throw at it. Very Happy with this Tripod!

I have had mine for a year using it with a 7D and a 400 f/4 DO. I switched two months ago to using it with a 5Diii and the new 500 f/4. A few days ago it snapped on me sending my gear falling. My friend using it luckily caught the camera before it hit the ground. I like it so much that I am buying two new ones to link with the one fastener. This should work for heavier setups

Advantages: So comfortable and fast to use.

Disadvantages: One cannot hold the weight of a body and 500 f/4 alone. Many people are using this handheld, so they need to strengthen the material.

Had ordered these twice and received the wrong size twice. Your customer service was very helpful and efficient. Received my correct order promptly. Very happy with my experience and will probably order a pair of these insulated for next Winter.

Replaced a 2 axis level lost recently after about a dozen years of use. This might be a record for hanging on to one of these little doodads.

Advantages: The 3 axis level works very well for quick leveling while camera is in portrait and landscape orientation. It fits tightly in the camera hot shoe.



Disadvantages: Only downside is its size. It is slightly larger than the 2 axis type. A very minor issue.

Great front cap that is tighter fitting than the OEM Canon cap.

Advantages: Faster placing and less bulky than the leather Canon cap.

Disadvantages: I may add a small pinhole to the rubber front center cap in order to equalize the pressure on the face of the lens so I dont force dust or dirt into the lens when placing cap on.

Nice idea as strap distributes weight off neck.

Advantages: Aside from nice weight distribution, it has the option of two cameras or a camera and binocular. Comes with additional strap set with clips.

Disadvantages: Plastic clips are not compatible with Optech or Canon CPS pro straps. Would have been five stars if it had.

What can I say, it's a foot. Works as needed. Naturescapes was a great seller. Will gladly buy from again.

This product failed me big time. The screw worked its way loose and the plate fell off--lost it--then the camera fell to the ground, defeating the point of having a safety plate. Now I have to buy another--I am NOT happy at all.

Advantages: It works--if it stays on.

Disadvantages: The screw worked loose, the plate fell off and I lost it--then the camera and lens crashed to the ground, defeating the entire point of buying a safety plate.

Seems to be a worthwhile alternative to the Zeck cap at one third the price.

Advantages: Price

Disadvantages: A bit cumbersome to take on and off.

Good Quality, Much nicer than transporting the lens in the hard case with the camera in yet another bag.

Advantages: Typical Think Tank build and quality. Works well with the add on bits from a belt system.

Disadvantages: Still pretty tight, length wise, with a Canon 500 f4 and body. Another inch or so would have been nice.

Well designed product...great for being hidden in position while waiting for that capture.

Advantages: Lightweight, well constructed, does not disrupt field of view, great coverage.

Disadvantages: When used as it was designed to be, there are none that I've experienced so far.

I found this book to be extremely helpful in deciding where and when to take specific pictures within the park. The book is well planned out and easy to follow.

Advantages: Good format, well organized and easy to follow. Hope to see more ebooks from this author in the future.

Although Aqua-Tech does make quality gear, I was not happy with the lens covers I purchased. They where to small, and the lens didn't even come close to fitting.

Advantages: Great neoprene protection

Disadvantages: Too small

These boots are great. They are waterproof enough to cross a stream 3/4 up my leg. The re light weight and pack small. Best news is you wear them over your regular shoes, so you pop them off and put them is a trash bag and are clean and dry for the ride home.

Advantages: see above.

Disadvantages: My buddy was kidding me that if both my feet got stuck in the mud the boots would pull my pants off because I keep them up with my pants belt. Not likely, but funny.

Better Beamer works exactly as described. It has really helped me improve the quality of my shots, especially on overcast days. On normal sunny days, I use the extender for "shadow: captures and it works far better than post processing. I received superb help from customer service in determining which version would fit my old but still useful Canon 420 ex flash. Really appreciated the assistance and the delightful attitude that accompanied it.
The Better Beamer is the best "High rate of return item" I have found in digital photography. Less than $40 buys anyone some really good shots and higher keeper rates.

Advantages: Focuses the light where you want it to go. Hard to describe how much better it is than simply using a normal flash.

Disadvantages: It is one more piece of equipment to manage.

I use several Think Tank bags, big ones. This bag carries all of the basics: D700, 24-70, 70-200, 1.4 telex tender, SB800 + stuff in a "quick grab", compact bag.

Advantages: Small and accessible. Think Tank tough!

Disadvantages: tight squeeze with the D700, no ID window.

It is not possible to buy this item in my country.

Best option monopod head for most.
I have been using the Manfrotto 3232 for years. This beats it in every way. Lighter, stronger, the tilt clamping arrangement is far easier to adjust, with a more positive lock. I've used the RRS one, though it's "better" it is overkill rated for 70 pounds or more, and costs a lot more. This strikes a better balance in size and cost. Fantastic product I've literally waited a decade for someone to get this "right"

Advantages: It's light, rated to handle plenty of weight, easy to adjust, and a bargain with the clamp and plate included, the head is practically free.

Disadvantages: Haven't come across any yet.

Don't know how I lost the bushings out of one leg of my tripod however I am truly thankful that NS had them in stock. Now I can stop pulling out the one leg and having to put it back in.

Advantages: Quick and fast delivery...oh and did I mention, NS had it in stock!!!

Disadvantages: None
