Oly Pen F + Mitty 7.5 + 80mm tube lens at 3.2X approx.

Bigger: https://images2.imgbox.com/1e/d7/gzGek7Qz_o.jpg

Best,

This is awesome!

Beautiful work, thank you for sharing! Which 80mm tube Len did you use? I am using Oly m4/3 camera (E-M1 mk1) too.

Thank you, Rane!

@zzffnn: Thank you! This stack is with Rodagon 5.6/80 from Scitex scanner, though a regular 80mm enlarging lens (Rodagon, Componon, etc) would do just as well.

Note that tube lens was mounted on Bellows and was not reaching infinity at minimal extension, hence the higher magnification. I don't see any significant degradation in IQ though.

Small sensors have their drawbacks, but also advantages. I can't think of many (if any) 0.20-ish optics that would cover reasonably well a 35mm sensor at around 3X.

I agree, but then at same magnification a 35mm sensor would cover almost 4 times the area. To capture the same size subject, your Mitty 7.5 would work well on 35mm fullframe with a proportionally longer tube lens.

Other than reduced size & weight, I'm not seeing the advantage of small sensor here. What have I missed?

For a given set of lenses, you get more pixels under a given FOV with smaller sensors than with large ones. That can be convenient sometimes.

I was trying to justify to myself the money I spent recently on the Oly. Thanks for ruining my attempt!

I bought it mostly for the Oly's pixel-shift, which I wanted to try, but it didn't convince me. It is stil a nice little camera with a great for the size sensor.

I love the pixel shift. Though now we can get the same thing on FF with the Panasonic S1-R. I think both systems have their advantages. For fieldwork the lightness, pixel-shifting, and fast auto focus bracketing of the PEN F are huge advantages. For studio work the FF Panasonic will give better image quality, but will cost a fortune, and may not really have useful auto focus bracketing.

I am really tempted by the S1R. Maybe it will be my self-gift for Christmas

Though launching price of high-end cameras nowadays is prohibitive...

Hi Macrero,
Great work!

Love the light and details

Thanks for sharing this great image

Thank you, Harald! Glad you like it.

I am going to take the plunge in a few days, though I will have to sell some of my high-end lenses to pay for it. But without focus bracketing (as the term had been used by Olympus), it won't replace my wonderful PEN F.

I still can't believe that nobody has yet made a FF camera that does focus shifting and pixel shifting. Nikon Z does focus shifting but no pixel shifting, and it seems the S1-R (can do pixel shifting but not focus shifting (except for a 7-shot bracket).

Nice! I look forward to seeing your opinion and tests.

I'll wait a few months to see if price drops...

The pixel-shifted sample on DPR looks impressive, yet the "regular" 47-megapixel image looks great too.
