Lens QA Works – optical design schemes: how-to

Intro

There are a lot of scanned optical design schemes in the network, but lensqaworks.com need to follow Creative Commons Attribution 4.0 International License in as many cases as it possible, that’s why just scanning and publishing of the books isn’t enough. For today the every single optical scheme get a personal approach, with researching over different sources and even consultations with collectors society. I’ve even found an errors on other popular sites.

Minolta SR-T101, three lenses and collectors disease

You know that photography is the most popular hobby in the world, and photo-gear collecting is linked very close with taking photos – I think that collecting has a chance to take the one of top places by number of involved contributors among all other collectors directions. Anyone can be a cameras or lens collector, independently of income, lifestyle and place of living. There was a lot of photo gear has been produced and every collector can choose the object in huge variety of prices, rareness and availability. Usually just what are needed – a few bucks, flea-market or postal office and a little empty space on a bookshelf.

Review: Chiyoko Super Rokkor 85mm f:2.8 Minolta

This is the lens from first years after WWII and it’s a part of history of Japans photo-industry, from the times when the poor and ruined country started the race against the worlds most famous corporations producing photo equipment and finally have won. The reason is clear – one glance at Super Rokkor 85mm is enough to see that it was created and built with incredible quality.

Some of amateur photographers says that they love real ‘glass and metal’ lenses, and this feeling drives them to create better photos than with lenses are built using plastic and rubber elements in construction. Quite often when saying these words they are holding in their hands something like Minolta MC or Canon FL or Nikon pre-AI, etc. I believe that these MC and FLs against this Chiyoko are looking like aluminum trinkets.

LensWars: Minolta MD 28-85mm f/3.5-4.5 vs. MD 28mm f/3.5 vs. MD 35mm f/2.8 vs. MD 50mm f/1.4 vs. MD 85mm f/2.0

One of the best zooms of pre-AF era is going to fight against famous primes on the most used focal distances. Yes, that primes are powerful, so the victory of zoom looks impossible but it will be great even if it can shows at least a close level of sharpness.

Welcome to see the comparison of Minolta MD 28-85mm 1:3.5-4.5 Zoom, Minolta MD 28mm 1:3.5, Minolta 35mm 1:2.8, Minolta MD 50mm 1:1.4, Minolta MD 85mm 1:2.0

Lens review: Minolta New MD (MDIII) Zoom 28-85mm F3.5-4.5 Macro.

Everyone knows the famous Minolta MD 35-70/3.5, which is appears wherever possible, but this MD 35-70/3.5-4.5 is much more hidden behind the scenes, and looks like a secret weapon for ‘those who knows’ – pathos words, but describe the idea. It has been tested by Great and Powerful Antony Hands in his The 35mm Shoot-out – as zoom which can compete with wide angle primes.

LensWars: Minolta MC Rokkor PG 50mm f/1.4 vs. MD I Rokkor 50mm f/1.4 vs. MD II Rokkor 50mm f/1.4 vs. New MD 50mm f/1.4

Here you can see the comparison of Minolta-SR 50mm lenses – from Rokkor PG up to New MD – all are the best classic 50mm lenses ever, and this selection of winner is just an option – photographers can use any of these lenses without any doubts and without reading of this article, but it was curious to find out how the Minolta’s optics changes from generation to generation.

The comparison is big enough and may be boring, so, if you prefer to realize details – you need a patience to look over all diagrams with samples, if you just interested who are winner – go to the end of article, but such way is not recommend, because it would be better if someone control the authors conclusion.

Note for collectors or those who know many about Minolta: ‘MDIII’ term is not using to don’t confuse the other readers, so plain ‘MD’ means ‘MDIII/New MD’ Continue reading LensWars: Minolta MC Rokkor PG 50mm f/1.4 vs. MD I Rokkor 50mm f/1.4 vs. MD II Rokkor 50mm f/1.4 vs. New MD 50mm f/1.4

Review: Minolta MD Rokkor 50mm F1.4 (MDI)

Another Minolta MD Rokkor 50mm F/1.4 lens review – 55mm filter thread, MDI version.

This is the first Minolta MD series lens with 50mm focal distance, and the second 50 mm lens in whole Minolta SLR career – for SR-mount cameras. The note about SR-mount is required because  there were a three 50mm lenses by Minolta for LTM (1947-1958?) – all three have been reviewed on this site, so, this article is about one of famous SLR fifty in the world – the great Rokkor MD of the first generation.
