    Interfit STR110 Reviews

    STR110 Strobies On-Camera Large Diffuser is rated 4.4 out of 5 by 27.
    Rated 5 out of 5 by from Surprisingly good I bought this to soften the light coming out of my Ray-Flash ringflash - the Ray Flash is nice, but the light that comes out of it is as harsh as the light coming out of your flash unit itself - harsh with a specular quality that shows up as shine on the nose & forehead of your subject. It turns out, with this, I don't even really need the Ray Flash. It produces a nice, soft all over light that's similar to a ringflash, but for a tiny fraction of the price, and it's a nice soft light to boot. It doesn't quite give a ringflash like quality - there is some sense of the flash coming from above/to the side of your subject, and actually gives a nice falloff from left to right in portrait orientation, similar to an off camera umbrella or soft box, but being so close to the camera there is some soft wrap around / 2 dimensional quality to the light that's similar to what you get with a ring flash. And at a tiny fraction of the cost & bulk, I'd be happy to take this with me over a small ring flash any day. Like the Ray-Flash it will interfere with your onboard flash's red grid for focusing, so this isn't great for use in near pitch black, unless you want to fiddle with spinning it around out of the way & then back again. It also works better with long zooms than with short fixed focal length lenses - simply because the longer the lens (physically long, not optically long) the futher it will away from the flash and the further the diffusion material from the light source, the more diffusion you get. I'm not sure how much light is lost through this, but I was able to get decent exposures from 10 feet away at ISO 100 at around F5.6 using a Nikon SB600 in TTL mode, and I was able to use it as a fill flash in broad daylight. I haven't tried it on group photos or anything other than portraits & a few still life tests. It looks cheap, and it is, but well worth it. It folds up in the same way as your diffuser/reflector and comes with a small (about 4 in diameter) zipper pouch. All in all, it's a simple idea that works well, and doesn't cost a lot Kudos to Interfit for coming out with this product. I hope it sells well so they continue to make it & I can be assured of having one whenever I may need one in the future.

    Rated 5 out of 5 by from Parallel uses I use this diffuser for natural (not flash!!!) light when performing macrophotography in the field. Enhances color rendition, softens light and eliminates reflection.

    Rated 3 out of 5 by from Odd but Somewhat Effective I got this to modify (soften) my flash in a situation where bouncing the flash would be impossible. I'm occasionally called upon to photograph events which take place in places where bouncing the flash off the ceiling isn't an option. I have a number of aids ranging from Tupperware Jugs to bent-up velcro(ed) flaps. As this one takes up very little room and was relatively cheep, I thought I'd give it a try. The lens attachment scheme worked OK and the flash is certainly softened eliminating most of the deer in the headlights look. It seems to unnerve some subjects as photographer is hidden behind the modifier but for snap shots on the fly it works pretty well. There is about a one stop penalty for using the diffuser.

    Rated 5 out of 5 by from Quick, effective, and cheap I prefer to have softer light so need some kind of diffusion so I love that they came out with this. Sure it's not the same as using an umbrellas or larger softboxes but it's more convenient which makes it perfect for events. It stores compact and sets up quickly.

    Rated 5 out of 5 by from excellent product! It's hard to beat this diffuser for the price and convenience. Easily the most portable of my diffusers, it provides very nice lighting in a pinch. In my opinion, the results are better than diffusers that are 8X the price.

    Rated 5 out of 5 by from It's affordable and it simply works! I bought this item based on a review here that likened the results to a ring flash. Well, after using this modifier to shoot my brother-in-law's wedding, I can happily say that it's the best on-camera light modifier I have ever used. You can shoot in TTL or manual even with the pop-up flash and this diffuser creates soft shadows that in landscape orientation comes pretty darn close to a ring flash. The shadows are soft and the color is great. You lose a stop of light, but you either compensate in flash output or you can correct in Lightroom/Photoshop. In portrait orientation, you get a slight shadow to the side, but it's still soft and the skin tones pop out with that fashion photography look. It's essentially the same effect as shooting through a small white umbrella at camera level. Yes, it's not as daring or creative as a multi-flash strobist set-ups, but it worked great for a wedding or party when I had to move from one spot to another, with little time to set up lighting and composition, or without the aid of an assistant. Of course if you can spring for a real ringflash or an adapter such as rayflash or orbis, then by all means go for it, but if you have less than $20, then skip out on the bounce cards (don't really work outdoors) and the Stofen domes (still doesn't significantly increase the size of the light source). I bought a Gary Fong lightsphere a few years ago and found it no better. You need a bigger light source and this is your best bet on a budget. It will tend to tilt forward or backward during use, but that's ok. Mine tends to tilt forward when I have it positioned between the focus and zoom ring. You can't really place it at the end of a zoom lens or else you can't zoom back to the widest focal length. I used it on a Nikon D90 with a 16-85mm zoom. Oh, and the bonus is that it provides a great conversation piece. When you don't need it, it folds down to a small size and fits into a 5 bag. Great stuff and highly recommended. Best mod under $20.

    Rated 3 out of 5 by from Some minor change, possible improvement This is a simple and interesting gadget with some minor light modifying effects. When used it brightens/lifts the shadows but it does NOT make the light softer whatsoever. The transition from light to dark is still very abrupt and the shadow behind the person is still very crisp and sharp if the subject is in front of a wall. Without the wall to reveal the shadow you still get that frontal assault look of on camera flash and the difference is really minor. I also think the example pictures provided are highly misleading and do not represent real results, I tried reproducing them and ended up with fairly harsh looking images. Bottom line. If you are using the camera flash for gentle fill only, it will make a minor difference. Otherwise, the results are too minor to notice and bother with.

    Rated 4 out of 5 by from Excellent product Pros: Beautiful direct lighting, not as direct as a ringflash, but kind of in between a ringflash a diffuser, for the price of a fast-food meal! Cons: Mooves a bit too much. Has to be replaced from time to time. But then again: A rayflash mooves a lot to, and costs 10 times as much. Stands too close to my flash to my own tastes, but thats my own opinion... Overal: Great lighting at low cost. Ideal for portrait on location, shooting the kids inside of the house, etc. Highly recommanded!!
