Rayonx 250 Zoom Test
1 Attachment(s)
I know a few of us here have been wondering how much zoom we should use to focus with when shooting with the Rayonx250, so I decided to do a test to see if this really does make a difference.

In this series of shots I left the tripod/camera in the same position and only adjusted the zoom. I started on full zoom 24x and zoomed down to 9x.

No.1 1/125, f5.6 ISO 125, Focale Distance 102.5mm

sorry about all the different posts, but it was the only think I could thing of to show the shots clearly and not have them all bunched up.

1/180, f5.6, 100, Focal Distance 44.5

and finally 1/180, f5.6, 100, Focal Distance 38.6

So it is possible to use the entire range of zoom with the RayonX 250 and have clear images ....... well I hope they are.

The photos are tiny flower buds........ spring is on the way in Normandy :D

very nice shots, good job.

You are lucky with the nature and scenery in Normandy ;-)

At the moment I am thinking about the Marumi DHG Achromat +5 instead the Raynox as a complement to the LC55.

I am sure you will make the right choice to suit you - that's what counts at the end of the day.

Thanks for doing these useful tests, I found if I used less than 3x zoom I suffered from vignetting (from the LA5 adaptor)

Was this with the camera set to auto focus or auto focus macro?

Square one-

Had you used the menu system to advise the camera that an accessory lens was in use? When that is used, the camera responds by not allowing the lens to retract to a point where vignetting takes plave.
