Snip:
If you even mention the Fong word on some photo forums (eg POTN or DPR) you'll be met with a barrage of derision and abuse. I try to be less judgemental, and while Mr F is guilty of some shameful advertising (he's not alone!) and there are better devices about IMHO, the Fong does actually work pretty well in most situations, including outdoors. The problem outdoors is it's massively wasteful of light but if you still have enough left with a decent gun used close, then fine. Same goes for a Stofen, but press photographers often use one of those for absolutely everything. It does the job and both the Fong and Stofen are fairly foolproof.
Thanks Hoppy, I'm glad I got an objective answer from you.
It seems the very mention of some photographic items instantly divides forum opinion into two camps, with personal likes or dislikes sometimes being banded about as fact, rather than (subjective) opinion, so thanks for not adding to my fears.
The photographer I was referring to wasn't Mr F, it was Martin Parr (for anyone unfamiliar with the name, Mr P has had a career spanning over 40 years, with around 40 solo photo books to his name, joined Magnum Photos in 1994 and is one of the best known documentary style photographers on the planet); and I believe he's regularly used a Fong type dome diffuser for the last few years.
Before I bought and tried a similar product it baffled me why such an eminent and frequently published Magnum photographer would be using a product that was so disliked by some on the forum? I wonder if this could perhaps be down to some people never actually trying the product (or trying it only briefly and not exploring it to the full) but forming a dislike of it all the same; and others trying it and not liking the results (or ergonomics) for their own particular style of photography. The latter one is fine, we don't all get on with everything and at least you gave it a go - nothing ventured, nothing gained and I'm sure everyone will be pleased that you found something that better suited your needs.
Anyway, in an effort to help the OP... After reading some reviews I took a cautious approach and decided to gamble £9 including postage on one of these:
https://www.ebay.co.uk/itm/Phot-R-P...h=item3ce6358181:g:tJ0AAOSwkLhaBhza:rk:4:pf:0
It's
not a collapsible version, but it does come with 3 insets that clip on reasonably firmly (I've not had one fall off yet). The 'chrome' coating on the silver plastic inset wasn't wonderful on the one I was sent, but for the price I couldn't complain - overall, it was better than I expected for £9 inc postage! It fits my Canon 580 EXII flash better than it fits the smaller 430 EX II, but putting a wide elastic band round the flash head before fitting it gives it more to grip against (if I can remember to carry one!). However, this budget version did enable me to try the general principles of the product without it costing me around £60 for the well known equivalent.
To be honest, and at the risk of ridicule from some, I actually like the results it gives. Yes, if not using it pointed forwards with the top dish pointing at the subject (one of the ways it can be used), it will 'waste' light (but less so if using the chrome lid with back reflector plate when using it in the vertical position). But it seems to give a nice, even light within its range and doesn't cast harsh shadows like direct flash. It's also more compact and less like a sail or flag than some of the large 'bendy plastic cloth' type flash modifier equivalents. Yes, the bendy type modifiers may do a similar job, and may be able to aim/direct light better (if that's what you need), but ergonomics and bulk can also be important factors to consider.
My review would be, don't expect it to be right for everything, or to be the universal answer; it's on-camera flash we're talking about, not a portable lighting studio. However, I've found that it's quite easy to use, it doesn't seem to get in the way too much if working in and around groups of people and I've liked the results it gives (within its range limitations). Will it suit the style of photography you do? Well, I paid £9 to find out.
Potentially, this approach could leave you lots of you £58 left to buy a 'budget' bendy plastic cloth type modifier and try that too? You can then make up your own mind and go from there before investing in a de-lux, high-quality version of the one you prefer; keeping the cheap 'trial' ones as spares or for off-camera, multi flash use, or pass them on to someone else via the classified ads on the forum or eBay and get some of your 'trial investment' money back? Hope this is useful and best of luck finding something that suits.
