    Olympus STF-8 reviews

    STF-8 Twin Flash is rated 4.0 out of 5 by 6.
    Rated 5 out of 5 by from A must for Olympus micro 4/3rds macro shooters. I am so glad I purchased this as soon as it came available, and whether coupled with my 60mm macro or 50-200mm+25mm ext tube I am getting great well lit images first time out. The lighting permutations are extensive offering various ratios between the heads or manual outputs down to 1/125th. The clip on diffusers do a good job of softening the light and improving coverage at 1:1 magification. It comes in a well made case and Rings to fit the 60mm which I own plus the 12-40 & 40-150mm Pro lenses that I don't but with the purchase of an inexpensive step down ring it also fits my 50-200mm+25mm ext tube with no sign of vignetting.

    Rated 5 out of 5 by from Pricy but worth it. I have struggled with using regular lights of all kinds for macro photography. The first pictures I took with the STF-8 demonstrated why I needed this product. Results were outstanding. The design is well executed. The size of the components are a bit of a challenge for someone with large (old) hands. The included case is just right to protect and organize the components. I believe this will be a very popular component for Olympus macro shooters.

    Rated 4 out of 5 by from Yes, I would go for it. It works well. The only negative is that the flash is not as powerful as I would like. It is great for insect photography or for really up close. Then the power is enough. I captured the image below by underexposing by about 2 stops. Did almost no post processing and think it came out quite well. I did try making my own difussers and using a small soft box on a handheld flash but prefer the twin flash. I would give it a 4.9 out of 5.

    Rated 5 out of 5 by from This flash takes my photos up a big notch! I took a big gulp at the price, but bought this flash because I love close up photography, and have found lighting to be challenging. I really love the many combinations of flash you can set for these 2 units, and the results are fantastic! They are a bit fiddly for bigger or arthritic hands, but once you get them set up, they are easy to use.

    Rated 2 out of 5 by from A flash of the superlatives, not all good This flash is amazing.� It is the most expensive unit I have ever bought, it is the weakest, it is the most complicated.� The guide number is only 8.5, which makes each head about half the power of the toy flash units supplied for free with the Pen series cameras.� Mounting the units on the ring is so complicated that I have never managed it in less than 5 minutes, and now I leave the heads on the ring.� And it only comes with two rings!� Even cheap units come with more than that.� And it doesn't even have a flash test button.� That may seem unimportant with a TTL flash, but TTL is not compatible with Olympus' focus stacking. I also have a Viltrox cheap ring flash (not sold by B&H), which cost me about 20% of the price of this unit.� By comparison, it works better, except for one thing: the TTL flash control.� But the lighting is more even, and it's so much easier to use that I hardly use the STF-8 at all. Not to be recommended.

    Rated 3 out of 5 by from competent but not convenient Oly did the bare minimum necessary to make this flash competent but nothing to actually make it usable on M4/3 bodies. I flash does work flawlessly and even well with focus bracketing but ergonomically it is a disaster and a tiny amount of attention from Oly could have solved that (if they cared). the screws holding the flash brackets on the adapter ring do not have slots and are basically impossible to turn with your fingers. I do realize that one does not change adapter rings often but at least enough that Oly puts 2 rings in the box and moving the mounts will leave you cursing Oly and their parents. See in the illustration how those thick curly cords are nicely separated from the flash. Not so much in real life. those enormously thick cords are a constant nuisance and are always in the way. for heavens sake, even Nikon uses a wireless interface on their ring flash.. any way if you plan to use this with the 30mm macro, good luck! it is a constant battle to get your fingers around the lens and honestly the 60mm is not much better even though it is a longer thinner lens. I rarely use this because it is such a hassle to deal with even though it does provide good results but it is just too annoying for any kind of regular usage and it really upsets me every time I do use it that Oly clearly cared so little about this not cheap accessory.
