Macro photography with reverse lens

 

Photo taken by Martin Carlsson using a Canon 5D Mark2

Me and my friend Martin Carlsson had one of our nerdy meetings yesterday. We didn’t have a real plan, more then go out for a session but weather was really as dull as it gets and none of us felt really happy about it so Martin came up with this truly excellent idea to try out some extreme macro using the reversed lens technique.

I thought the idea was brilliant, especially in mind that I had my trusty 70mm macro that probably would become like a microscope and what if I turned my 120-300 bigma around? Would that make me see atoms for real? I was pretty sure I would so we made a setup with my Quadra, a bunch of lenses and a VISA card. Mostly because people know what it looks like.

Now, here’s a shot with the Sigma 70mm Macro NOT reversed. You get pretty close by doing nothing, just using it as it’s supposed to be used. This is as close as you get. (and don’t you dare try using those numbers!!!)

Now I reversed it but to my surprise nothing much happened. I didn’t get any closer. hmm. I ran out getting myself a bigger gun. My 70-200mm 2.8 lens. I swong it around and it gave me less then the 70mm, at least at 200m. 70mm looked closer. So I figured that my assumption of more mm was wrong. So I got myself my 17-70. At least I could try and see if wider meant closer.

Sure enough, soon I was traveling over the VISA cards surface and maan was it a beauty. I never thought a piece of plastic could look this beautiful. Close to the same feeling looking at Avatar in 3D for the first time. :D

So if 17mm meant closer what was my next step? The 12-24 (which Martin now tried in the background) was a bit tricky because of the round frontal lens. But I did have something even wider – my 10-20!

Now, the 17mm was difficult enough to control. Every breath and dare I say heart beat effected my steadiness greatly and things didn’t get easier with the 10-20 at 10mm. It was really tricky, to give you a feeling for how shallow depth of field is I tried to catch the top of one of those small letters on the card.. See how background fades away! Nice bokeh too! :D

It was EASY to miss, either you got the top, bottom or just a big blur. All depending on who touched the table or walked the floor or if a big bird flew outside my window.

Now, what’s next? All above shots has been taken wide open. I had no idea how to change aperture on a lens that wasn’t mounted but Martin had an idea. By changing the Aperture while mounted he then pressed the “aperture test button” and while holding the button he gently released the lens and oala – aperture was still at wanted f-stop! Now things got even more interesting!

How about Linns face at f8 – f32?

Or why not some fine salt? (not sea salt or anything huge like that)

Or the landscape of a swedish 20kr bill? And yes, the black part of the image was me not holding the reversed lens perfectly aligned. It wasn’t that easy!

And finally Martin started staring into a good old light bulb – as if the quadras flashes and strong LED wasn’t enough disturbing. I’m pretty sure Martin took some better shots with his 5D but here’s my only sharp one. Or at least, a bit sharp. Lamp never stood really still and it was terribly hard to take a decent shot.

But I got pretty close! :)

Alright, if you have your own shots to share, then please do! (it’s easy to do when you post a comment).

Canon EOS 5D mark II as a video camera! :D

Alright, it looks like I’m more or less in panic mode here but that’s true. ;) I made so many edits, took scenes away and this and that – and after each time I processed the movie and was ready to upload – there was something that I wasn’t satisfied with. I have five different versions of the same movie with four different “pre talks” and finally I settled for this one. It has the worst beginning but hey, it’s me. :D – still it’s a bit long. It’s also supposed to be fun for my sister and her family to watch. :)

– less compressed than youtube version and more smooth in playback.

So how do I like the 5D Mark II compared to what I’m used too? Well, first of all – it’s a great tool! It’s easy to work with even if I’m missing some buttons – as a movie camera it’s great! After a day or two you feel that you have it all under more or less control and you can start to relax. It’s such a nice feeling to be able to go up to ISO6400 (or even higher) and still feel OK – and in really bad light too!

But, as a still camera even in good light I don’t like the output as much. I can’t get “that” from it – and I’m not that impressed with the 21mp resolution. Strange feeling zooming in to these large files and feel like like there should be more. Never feel perfectly satisfied. Oh well. The burden we three layer lovers have to bare.

But when light is bad, and ISO goes up then it leaves my Sigmas in the dust – you can take brilliant shots in ISO3200 (didn’t try much higher, only with video) and I always felt secure without extra light or the need of a flash. So would I like to own one myself? For sure! I can easily imagine myself doing weddings filming and taking pictures at the same time. At least try. :) Especially inside church where I today feel a bit bound by Sigmas bad light performance. But why is Canons shutter so loud?? aaaaa

Thoughts of today – Canon 1D Mark IV & Nikon D3s

Much can be said about the specs of each of these beasts – but nothing for me more interesting than the possibility to grab stunning video or perhaps I should say film – it’s far from “video” in my book. Myself has been waiting now since forever for Red to release the Scarlet but it seams to be delayed – and the biggest difference I think between these two new players is RAW footage. And that’s probably also why I will wait a bit more before jumping on. I think I have a movie director inside that wants to come out. That said, I’ll continue to use Foveon equipped products.

Impressive, isn’t it? Consider that both these cams can go all the way up to ISO102400, which is really insane! Compared to RAW footage possible with a RED, above shots still looks good but somewhat video. Did you notice how Canon footage look Canon? A special brownish tone to skin and enviroment that’s always there in low lit situations. Still impressive. :)

(HD720, h264 around 500MB size, but well worth looking at) – Oh, the Mysterious-X is on it’s way too – the next generation sensor from RED that will be even more impressive. Starting at a clean ISO800. You surely need lots of ND’s to do outdoor footage with any depth. You can follow some of that here.

Now, looking at all these mighty riders in shiny armor – when do we see the Foveon sensor do film? (except DP) It would probably not be able to go as high ISO wise but colors and definition will surely be in another league. Especially if it will be able to record in some type of RAW format. Should be possible if you consider what RED team has been able to do.

I still enjoy the possibilities provided by the DP1 and DP2 – and it shows that it’s possible. But still, resolution is way too low. :(
