long term review of the laowa 25mm x2.5 x5 macro lens. with some samples and tricks. no insect were hurt for this video, they've been found already dead.
Incredible. This is beyond practial though and is reaching into the ridiculous levels of difficulty. You have far too much patience and dedication, impressive!
Merci beaucoup ça permet de voir votre vidéo permet d'en voir beaucoup sur les techniques de macroscopie c'est vraiment gentil de votre part d'avoir pris le temps de le faire
I love your videos and can't believe how lucky I was to stumble upon your channel. Your attention to detail is fantastic and love how you've DIY'ed so many different setups. A great inspiration!
Stunning. Thanks for sharing your workflow. I'm in the throws of upgrading to a lens like this after testing extension tubes. Still deciding on magnification. I might just stick with 1:1 or 2x. Anything more is too extreme for me.
Danke das du uns die seltene Möglichkeit gegeben hast diesen wunderbaren Insekten so nahe zu sein Ich würde gerne viel mehr davon sehen Vielen vielen Dank
I am very impressed with your ingenious solutions for field stacking! I came up with a very similar device but it was too bulky for practical use in the field. I am working on a new system that uses the tiny sled stepper motors from DVD drives, but they lack the torque to drive the NiSi rail accurately. What motor are you using with the rail - it looks like a regular DC motor - and what are you driving it with? Thanks for sharing this excellent footage! Allan
to control the dc moteur in outdoor i use this guy, only for continuous rotation www.ebay.fr/itm/255548064979 the motor is like this one but at 45 rpm www.servocity.com/precision-spur-gear-motors/ the coupling part is smth like that : www.gotronic.fr/art-coupleur-d-axes-5-5-mm-cl1m55-26414.htm or www.gotronic.fr/art-machoire-d-accouplement-10-mm-cl12-10-33140.htm indoor to be accurate i use an arduino and a l298n , you can make a run stop shoot run www.robotshop.com/en/dc-motor-driver-module.html the motor is a 6 rpm i think the best way is to use a step motor but i don't have this skill if you have monney you can directly go here : www.mjkzz.com/?fbclid=IwAR3lqizdCU0vBGX-9XwLg280NyOZ-QVg036oylfdcll9gjf8jsM_YjYptIg
Great shots with the ants when they were eating in food, were any of them focus stacked? I was suprised that some of them wherein sharp focus from the front to the back!
if you talk about the footage at 14sec, i chosse an APC-c sensor, add 2 leds spots , and close a little bit the aperture, increased the ISO, and try to reach 1/50sec. all the little trick to have a bigger deep of fied in video. i don't know how canon manage the sensor in full HD video, but the deep of filed is not sod bad. for a 20mpx picture it is another story.
Thanks so much. One more thing…. in your video you show some 3D computer generated devices which you seem to use on controlling camera position and maybe focus. What are these and how can someone get them? Do you have a video on them?
Wow this is really magnifique❤. You have a macrorail that is motorized? I want to use the lens for iris photography of the eyes, can that work without a rail ( i have a manual nisi)
Thanks for making this. I just bought the lens and happen to also shoot the R6. Im shopping rails now. Can I ask how you got so many exposures so fast? Jpeg?
with the R6 i use an high speed card in raw, the buffer/RAM can shoot continuously at 20 img/sec during 6 or 7 seconds (numeric shutter) . as i use no flash in outdoor with the diy motorized rail the parameters are 2,8 to be as faster as possible (about 1/200 or 1/320) . i use helicon focus. but i guess the jpg is the best way.
It à simple do it yourself motor drive by a basic variations or à L298N with arduino . the rails used is are from Nisi and Proxxon. The tripod à cullman one.
I'm curious; if the insects are dead why do you need to shoot in such a short time. I appreciate it makes things easier, but if I can't afford a motorised system can I manually stack using a macro focus rail ?

on the R6 canon there is the option: exposure simulation? but at f2.8 normally this is where there is the most light. But as I don't use flash I keep a speed higher than 1/60, I stay at 2.8, and I increase the ISO if necessary up to 6400 max
@@stephanesimoens51 Thanks Stephane, I tried the lens on a really old Nikon (D7100) and suddenly I can see through the viewfinder. It appears that the mirrorless camera is faked out by not knowing the F stop so Nikon in their infinite wisdom appear to have made an assumption that it's f32 and shut down the sensor. On the reflex camera it does not have this issue. Weird, but at least now I can turn to Nikon for an answer.
hey man ,love your shots. Is it possible to get similar quality/ ultra macro without having a rail? I know how to focus stack, but could similar effect be achieved just by closed aperture plus strong flash + diffuser? or is focus stacking always better?
the issue is the aperture, at F11 most of lenses create diffraction, and the image become less and less sharp. it get worst at F14 F22 etc.. another way could be use a macro lense with a shorter focal combine with a small sensor. a micro four third mcro lense with a Olympus OMD is a good combo.
@@stephanesimoens51 appreciate the response! I use the sony 90mm 2.8 macro and have also the raynox 250 extension.. you are right though i just hope to avoid complex post processing :D and for some reason always have issues with focus stacking (i do it handheld not with a rail)

Yes. The contactors of the extender are cover by a tape. So the dslr does not detect the électronic and works well. I add a short extender tube between the lens and the extender to avoid clash. I tried with x2 and x1.4 on apsc and it was close to x20. But the top of the laowa is very close to the subject.
3 or 4 godox led 64 with tracing parper for a better light diffusion. but a 5w light can work too, until you add something to diffuse the light. hte idea is also to not making too mush heat.
@@stephanesimoens51 oh i think these will be perfect. i need good video lights for macro stacking, which can be powered externally but also because i dont want to use flashes inside my room. Thanks
It is a DIY modified NISI rail, here my last version design: speed regulator MFA 919D2P CC motoreductor HPCB 3046 1/1000 POLOLU gear setup here for 3d printing, fit only with the first release of the NISI rail : grabcad.com/library/gears-for-nisi-rail-first-model-of-the-rail-1
The idea is to kept the same speed abd try to be at 1/200 at least. 1/500 is better. During 1/500 sec the mouvement is so short tgat there is almost no difference with à fix position. But if you move too fast the deep of field is too narrow to cover the displacement
the XT3 electronic shutter is about 11 images/sec it could works, but i have no idea how many time it can do it (buffer ) . you may also try in 4k video.
