Review: Minolta MC Tele Rokkor HF 300mm 1:4.5 (MC I)

Minolta MC Tele Rokkor HF 300mm 1:4.5 (MC I) lens review

It’s difficult for me to make an objective conclusion about this lens – I don’t use such focal distances in real photo-sessions. This is for something like birds or foxes or maybe for Moon. Anyway – I can test it over the standard way.

After getting a new lens, I always take a few technical shots to understand its strengths and weaknesses – usually, it helps me a lot to start using an unknown lens with much less of doubt. One day I decided that my data might be interesting for someone else and this site has been made.

(Please, forgive me the dust on the lens, I never have the patience to clean objects for close-up photo sessions)

On camera Minolta SR-T101. Nice view, by the way – this camera is a big brick of metal, but here looks very elegant:

The short story about how did I get this lens can be found here:

Lens code name – Mikasa Ackerman:

Mikasa Ackerman (ミカサ・アッカーマン Mikasa Akkāman?) is the adoptive sister of Eren Yeager and one of the two deuteragonists of the series, along with Armin Arlert.

After her biological parents were murdered by human traffickers, Mikasa was rescued by Eren Yeager and lived with him and his parents, Grisha and Carla, before the fall of Wall Maria. She is the last descendant of the Shogun clan that stayed on Paradis Island, thereby related to the Azumabito family, and holds significant political power in Hizuru.[11]


Sharpness – close distance:

Test description: target is a 10×15 cm picture (printed, glossy photo paper), fixed on the wall by scotch. Distance – 1.7m. Camera Sony A7II (24mpx, full frame) was fixed on the tripod and managed remotely with computer display as a viewfinder. All groups of shots were repeated 3 times for every target position on all apertures from fully opened up to F16, ISO-200, WB – same for all shots. SteadyShot – OFF. Focus was manually corrected for each shot. After all needed shots have been taken for one target position – I moved the target to the next place. Main idea – to exclude the field curvature affect on so close distance. Of course, I can’t be absolutely accurate, but test results looks correct.

Finally, pictures were converted from ARW-files in Capture One with default settings (Some single files have a slight light correction, for better visual convenience in comparison), then cropped for 300×200 px elements, combined into diagrams and exported into JPEG-files

Sharpness – long distance:

Test description: Camera Sony A7II (24mpx, full frame) was fixed on the tripod and managed remotely with computer display as a viewfinder. Targets (buildings) were fixed by gravity power on the distances in more than 200 meters. All shots have been taken with apertures from fully opened up to F16. ISO-50. Shutter Speed – depends on light (camera A-mode), WB – fixed and the same for all shots. SteadyShot – OFF. Focus was manually corrected for each shot to exclude focus-shift affect.

Finally, pictures were converted from ARW-files in Capture One with default settings (Some single files have a slight light correction, for better visual convenience in comparison), then were cropped for 300×200 px elements, combined into diagrams and exported into JPEG-files.

Long distance bokeh:

Test#1:

Test conditions: lens was focused on minimal distance 4.5m, houses were fixed in infinity distance on the ground.

Such scenes can’t be meet often, so this is a demonstration of extreme conditions. In most cases of real-life photography the blur level will be less, see the next Test#2.

(frame scaled 1200×800)

Test#2:

Test conditions: lens was focused on 8m – in the middle of the range, houses were fixed in infinity distance on the ground.

Light dots long distance bokeh:

Test #1

Test conditions: lens was focused on to minimal distance 4.5m, lights were fixed in more than 200m.

Such scenes can’t be meet often, so this is a demonstration of extreme conditions. In most cases of real-life photography the blur level will be less – see Test #2.

Test #2

Test conditions: lens was focused on 8m – ‘portrait distance’, houses were fixed in infinity distance on the ground.

My overall conclusion about the Minolta MC Tele Rokkor HF 300mm F/4.5 (MC I):

MC30045__Avatar.png

Of course, the weight of this lens should be mentioned: 1150 g. For example, younger New-MD modification is 705g, lighter for 445g. Tests results show that this lens doesn’t have something which can compensate for the weight. The IQ is nice, but without surprises, looks standard for long lenses of that era.

Everyone who says on photo-forums something like ‘real steel lenses are the best’ – have to get this one and enjoy. For collectors this lens is also ‘must have’ – a beautiful example of engineering from ’60 which can be acquired for a reasonable price. And if you put it on the shelf, it will amaze your guests.
