Medium format legacy lenses: sizes and specs

Sea garden hotel

Last time we talked about legacy lenses for the 35mm format. Now it’s time to step up the game, size-wise.

35mm legacy lenses: sizes and specs

Stream in a gorge in the forest

Every time I was out shopping for a legacy (or just plain old) lens I had to dig through piles of old magazines and bookmarks to find the info I wanted. Especially dimensions and optical scheme of an old lens are often two difficult data to track down.

So I started collecting all these specs into this handy table, that I’m now sharing with you. Continue reading “35mm legacy lenses: sizes and specs”

Top 5 film cameras (+ 1) under 500$

Top five best film cameras for less than 500 euro - Pentax ME Super

A couple weeks ago Kai of DigitalRev, with the help of Bellamy of JapanCameraHunter, did a video on the “5 top film cameras for under $1000”.¬†Interesting, but having grown up shooting film in my opinion they got two major things wrong. Continue reading “Top 5 film cameras (+ 1) under 500$”

Battle of the 50s: an update on the Pentax Takumar “war”

Pentax Takumar 50mm f/1,4 compared

Like I reported in the previous post Battle of the 50s, the two Pentax Takumar currently I own, both 50mm f/1.4, behave in a striking different way regarding the depth of field at any given aperture.

The 8-elements in particular exhibit a much more extended sharp field, compared to its sibling.

This gives to it probably even a slight margin in the sharpness department, if not for anything because the focusing it is less critical.

Both of the pictures above were taken focusing with the aid of the 10x zoom in Live View on the tree in the center, that was nigh at infinity, on a Canon 5D Mark II. The roof in the foreground, instead, was at about 10 meters.

The details are from the dead center of the frame, and both from shots made at the same stop: f/4.

I guess that the optical differences – sharpness aside – between this two lenses are more deep that the elimination of just one element…

As a side note you can also appreciate the wildly different tint each lens has.

And yes:

  • white balance was set on “Daylight” for both pictures
  • they have been taken just a few seconds apart from each other, without changes in the ambient light
  • my sample of the 7-elements 50mm f/1.4 Takumar hasn’t yellowed

Unlike the different depth of field, though, this would be easily modifiable in postproduction to make the two results look more alike.
