Wow, the 150mm printing Nikkor. I have to admit that I'm jealous, now. You seem to own a very nice macro lens collection.

Best regards, Christian

Yes, after many years of waiting in the earlier years. I once found one Ebay seller offering both the 150mm and the 105mm. I got the 150mm then and the 105mm some years later. The 50mm and 25mm Photars are probably the best of others. A lot depends on the magnification for the more exotic ones and most require extensions.

Sony A7r3, 45mm extension, Rayfact MJ90mm f4 at f11, furthest focus (first two, FOV 60mm wide) then closest focus 1:1.

I wasn't as interested in pretty pictures as what the lens would do.

It may be of interest that, on the A7r3, the Rayfact MJ 90mm on extension gives:

On 3k, 4k, and 5k Nikon F extension (total 45mm, half focal length) it gives 35mm to 60mm FOVs. An additional 65mm extension gives FOV 20mm to 27mm. (No images yet)

I am expecting a delivery of more tubes next week.

Sony A7r3 Rayfact 90mm on 45mm extension at f11 then f8, twin flash, ISO 200, hand held.


These were shot at slightly different angles. I rotated the pot, in relation to the flash guns, to get the two flowers in the same plane of principal focus for the f8.


There is a slight optical illusion from the pattern in the right flower on the first pair.

A superb selection of subjects.

I have the Focotar-2 50mm so now I am encouraged to use it more.

Classic Cars April 13, 2025. Sony A7r3, Minolta MD 50mm f2 at f11, except engine f8, hand held.


Some of the cars were lit by mottled sunlight. I exposed for sun.


There are some spooky effects in some images.


I have adjusted some shadows and highlights.


This was the first time I tried the lens. I fitted a short hood. I think I have found the 50mm for my A7rs.

Again, with my Minolta 50mm lens on the A7r3.

I have added a single frame of it arriving.

The badge says "Tiger Racing".

My previous images were shot with flash and with flash white balance. They came out rather pink.

These shots are with the same setup but in cloudy daylight and cloudy WB, at ISI 800.

They were pink again. In the Sony "Editor" only one frame showed as blue. This is worrying.

These images are after adjusting hue in PS.

As I thought, it is the sensor, just as color transparency film had the same issue with bluebells.

This is the one(s) I bought. I have in mind moving subjects, pressing both shutter releases at the same time.You need 2 cameras and two reasonably-matched lenses (focal length), with adapters, if necessary. It was the latter which delayed me, GAS now having prepared me.

Here are my original and the Chinese one.

The original was made by Jasper Engineering of Mountain View California (no longer available) length 255mm. It has a bubble for leveling.

Bush centering 227mm vs 230mm apart. Eye centering ca 80mm apart.
