Received in a slightly thicker, single-color printed and otherwise neutral box.
In this is the K&F Concept 65cm/26 inch lantern softbox, with protective bag and German instructions (Fig. 1).
The workmanship and material leave a good and robust impression, so you can assume that the whole mechanism and material will be able to withstand a lot of assembly and disassembly on different sets.
This is my first "lantern softbox", but otherwise I have a number of round and square standard softboxes in different sizes in use and was curious to see what this type of "lantern softbox" has that others may not have.
Assembly and disassembly:
First the "assembly", and it's a joke, almost ingenious. Simply prop the flat end (Fig. 2) up on the floor, slowly press the Bowens flange down until everything is tightened, attach the locking bracket, that's basically it (Fig. 3), done in seconds, if necessary open the Velcro fastener at the back a little and move one or two spokes into the right position (small picture in Fig. 4), also works from the outside.
No more tightening/attaching of attachment diffusers etc.
The assembly is just as easy, flat on the floor again, slowly press the Bowens flange down again, unhook the locking bracket (done in 3 seconds), and off into the protective bag.

Use:
It is difficult to compare to standard softboxes, or to make a real comparison and describe it here.
My subjective impression as an ambitious hobby photographer and sometimes also as a contract photographer.
The illumination is noticeably wider-angled and a little softer than with the standard softboxes, especially of course compared to the parabolic softboxes, but I need a little more flash power to have the same illumination intensity on the person or the object to be photographed.
The cast shadow also seems to dissolve a little more with this "lantern softbox", but it is only very marginally noticeable. However, a few 10-20 cm further away from the person to be photographed, e.g. from a white wall, is enough to achieve a "perceived" equality.
As I always work with at least two flash heads in my studio rooms, this point ultimately doesn't really matter, in other words, the "lantern softbox" offers no noticeable advantage here.
The main advantage of this "lantern softbox" is clearly the incredibly fast and absolutely simple setting up and taking down function.
I can have this "lantern softbox" ready for use on the flash head in seconds. Depending on the set conditions and shooting requirements, you can even get by with just one light source due to the wider-angle illumination, but you will then need a few power reserves in the flash head.

In my opinion, it may also be ideal as a wide-angle fill-in flash for outdoor shoots, provided there is electricity available or a power battery flash on set.

Summary:
The workmanship and the material also allow for semi-professional use, especially with regard to the functionality that can be set up and taken down in seconds and is easy.

Even compared to standard softboxes - and especially compared to parabolic softboxes - there is noticeably wider-angle illumination, almost no "spot effect". This also means that cast shadows are even more resolved.

However, this comes at the cost of lower brightness on the object being photographed, which may then have to be compensated for using the appropriate camera or flash settings.

Even if you already have one or two softboxes on set, at a current price of under €75, it is still a recommended addition. As one or two additional and complementary light compositions are still possible here.

Also very useful as a very quickly available stand-alone fill-in flash solution for photo sessions of smaller groups of people, as there is ultimately no spot effect or darkening of the corners until the outer areas of the image cut.

In summary, an extremely fast and very easy-to-use softbox solution, with very wide-angle illumination, with an even greater resolution of cast shadows, but which also requires a little more "flash power".

Also a great addition if you already have one or two softboxes in your photo equipment.
Wahrlich in Sekunden habe ich diese „Laternen-Softbox“ einsatzbereit am Blitzkopf.
Je nach Set-Bedingungen und Shooting-Vorgabe, kommt man jedoch zudem sogar - aufgrund der weitwinkligeren Ausleuchtung - mit nur einer Lichtquelle aus, benötigt dann jedoch ein paar Power-Reserven beim Blitzkopf.
Aus meiner Sicht ggf. auch ideal als weitwinkliger Aufhellblitz bei Outdoor Shootings, sofern Strom vorhanden, oder ein Power Akku Blitz am Set ist.

Zusammenfassung:
Die Verarbeitung wie auch das Material lassen ohne weiteres auch semiprofessionelle Einsätze zu, vor allem im Hinblick auf die sekundenschnelle und einfach Auf- und Abbau Funktionalität.
Auch schon im Vergleich zu Standard-Softboxen - und besonders im Vergleich zu Parabol-Softboxen - eine erkennbar weitwinkligere Ausleuchtung, fast keinen „Spot-Wirkung“. Damit einher geht damit auch eine noch weitere Auflösung von Schlagschatten.
Dies wird aber mit einer geringeren Helligkeit am zu fotografierenden Objekt erkauft, was dann ggf. über entsprechende Kamera- oder Blitzeinstellung kompensiert werden muss.

Auch wenn man bereits die ein oder andere Softbox am Set hat, bei einem aktuellen Preis von unter 75,- €, dennoch eine empfehlenswerte Ergänzung. Da hier doch noch die eine oder andere, zusätzliche und ergänzende Lichtkomposition möglich ist.

Auch sehr gut einsetzbar, als sehr schnell verfügbare stand-alone Aufhelle-Blitzlösung bei Fotosession von kleineren Personengruppen, da bis zu den Außenbereichen des Bildschnittes letztlich kein Spot-Effekt auftritt, bzw. Abdunklung der Ecken.

Zusammenfassend eine extrem schnelle und sehr einfach zu handhabende Softboxlösung, mit einer sehr weitwinkligen Ausleuchtung, bei einer noch weiterergehenden Auflösung von Schlagschatten, die jedoch auch ein wenig mehr „Blitzpower“ benötigt.
Auch eine tolle Ergänzung, wenn man bereits die ein oder andere Softbox in seinem Foto-Equipment hat.
