NEW Advanced Assignment # 2: Macro without Macro

@SerbianAdonis: Glad to see you're having a good time with this one, Bata! These all qualify as a pass for the assignment. Well done

Cheers... Brian

Hi, I'm new here! I got referred to the assignments on the "New to dyxum" thread ;)

So here I go! This one was taken using my 18-55 kit lens. It was simply reversed and set to approximately 28mm. I used the camera's flash for lighting.

I am not 100% sure that this is 1:1 or higher, but it seems pretty big to me. It was cropped a little bit on the left, just to center the O.

It's a Minolta 35-70 lens cap.

Having figured out the old 35-70 F4 gives pretty good magnification with extension tubes added I'll have a go at this one.

Single areole on an Opuntia microdasys rufida, about as close you'd ever want to get to those minute glochnid spines. Whole areole approximately 2-3mm wide.

A350, 35-70 F4 at "macro" setting with a total of 68mm worth of tubes attached. No flash used but a diffuser on the sun side and reflector on the shade side to even the exposure. No cropping used.

Thanks
Think when I did my test and calculations that I ended up in the 1.7:1 region, with a workable minimum focus distance of around 5cm from the front of the lens.
Got a macro rail, acctually a complete Auto Bellows 1 set, in the mail heading to me right now that ought to make focusing alittle easier in the future.

You passed with flying colours beardedspoooon, I especially like the first one. Very innovative macro set-up and good composition to boot.

@DrSpinorial: That works! You get a pass to your next assignment. Cheers... Brian

This was done with my 18-55 kit lens on a reversing ring. Because the lens wasn't talking to the camera the EXIF isn't very informative but the data is:
Lens zoomed to 35mm
ISO 100
Shutter: .4 sec
Aperture: Opened up about 5mm of lever travel using a paper clip. No idea what F stop that is. Around F11 maybe?
Manual exposure +1.3EV
Lighting from a strong desk lamp up close.
Not much post processing. No cropping.


EDIT: Forgot to mention it was taken the day it was posted - 21 June. Camera was an A58.

The pen measured about 8mm from tip to bottom of circle on nib:

I'd put the magnification at around 1.6x.

Enjoyed this!

PS Can someone explain to me how it's possible to manufacture a good quality reversing ring, market it on eBay & ship it internationally for $USD2.33? Amazing.


Cheers
Tony
