Hi guys, anybody tried one of those led macro rings on ebay (the £30 jobbies) are they any good? cheers guys!
 
yeah I understand that JD, I just wanted to try a bit of macro on the cheap to see if its for me before any major outlay but quickly worked out ive got to work some lighting out! imho :)
 
As long as your not going above 1:1 diffused hotshoe flash will be just fine - the led's are just not powerful enough
 
I think they're a great idea, if only they were a bit more powerful, like maybe a couple more (switchable) rings of LEDs for another ten quid and they'd be great.

Big advantage is that you can see what you're doing.
 
Dogfish, man they are awesome! well done, "above 1:1 diffused"? could you explain plz. that bug in the bubble :) I guess you dint use the hotshoe flash for them eh? I take on board hoppy there may be a power problem here :) thanks for the replies guys :)
 
Paul just added you as a contact on flickr cant believe Ive not added you before :thinking:

Id be interested in the bug in a bubble, was it just a lucky find and did it get free?

When shooting macro the distance from the end of the lens to the subject is quite small (MWD - Minimum working distance) and the lens can block the light from the flash from reaching the subject which is one of the reasons people use a ring flash (personally don't like the light from a ring flash) or a macro twin flash like Canon's MT24-EX or Nikon's SB-R1. If your using a macro lens 100mm or longer with internal focusing this shouldn't be an issue, have a look at this thread for some inspiration.

I used a MT24 with my MP-e for the bug shot - i only have 41mm working distance at 5:1 and the lens is 230mm long making the subject 270mm away from the camera, also at 5:1 the viewfinder can be quite dark and the MT24 has 2 led's built into the flash heads to add some light to help with focussing.

a 1:1 macro lens will project a life size image onto the sensor of you camera so if you a picture of a ruler at 1:1 you see (on a crop sensor 22.3 x 14.9 mm on a canon)

and at 1:2 (Half life size) you see

Dave In the space of about a week last year i found 2 separate bugs trapped in / on a rain drop which i photographed, and despite constantly looking I've not seen it since :thinking: - I gave each bug a helping hand after their photo-shoot and sent them on thier way.

Paul nice explanation :clap:

Ive never noticed a bug stuck in a drop before, Im going to look harder :lol: , well done helping them out :clap:
 
Thanks for the comprehensive answer Paul I understand now, ive got 2 speedlites so I may be able to light up with those! im using a ef100mm macro but I guess you use something else to get in there so to speak and achieve a 5:1 ratio? or is it the 5D mk3 :) thanks again for your interest in my posts
