Phil's take on "our Mary"

[Ozzie_Traveller]

G'day all

Seeing GJ's efforts with his new Tokina spiked my curiosity regarding the Lumix in 1:1 mode ... so here's some comparisons
Maybe a big difference between the 2 systems is that the Lumix at 1:1 mode is 2,5cm from filter ring to subject. GJ- how does this compare with the Tokina??

Phil

1) test image [all are SOOC except for cropping & resizing to 1000px wide]

2) turned to 30 deg to get corner-to-corner image for sharpness check

3) 3x images .... F2,8 top - F5,6 middle - F11 bottom

As always, feedback welcome

Phil, the Tokina is at 1:1 mode when the subject is 300mm from the camera's sensor (film plane in the old days). At this point the fornt of lens is ~110mm from the subject
The sensor position is usually marked by a white line on the top of the camera body.

The small circle with the horizontal line passing through it represents the sensor.

G'day GJ

Thanks - I'm well aware of the film plane / sensor indicator

My main reason for mentioning the "bluddy-close" distance was the shadow-on-the-subject issue when one gets extremely close when -not- usinsg a proper macro lens, where its optics have been designed for a good stand-off distance

ps- what pleasantly surprised me was the corner-to-corner sharpness, even at max aperture
