I have two hobbies: Photography and photographic gear. Both are related only to a small degree.

A look into Phillip’s camera bag – September 2019 Edition

After the favorite lenses series fell dormant I thought it would be interesting to give an update on our current gear which has changed a bit and change the format a bit at the same time. So feel invited to have a look into my camera bags.

If you purchase the lens through one of the affiliate-links in this article I get a small compensation with no additional cost to you. 

The Bag

I use a Think Tank Turnstyle 10 V2. The bag fits a camera and 3 medium sized lenses.The biggest argument for a shoulder bag to me is quick access and that it is more ergonomic to carry than a messenger bag. The bag works really well for not that long hikes without a backpack and when I am on my bike. I have carried it besides a daypack on longer hikes and that is anything but enjoyable. A Mindshift Gear 180° Panorama Backpack would be a much better solution but those are expensive.

The bag just feels like a very well made, well engineered product from a company which knows how to make good bags. After nearly two years of constant use it shows few signs of wear. Even though I forgot to close the zip several times I never lost a lens thanks to its clever design which keeps lenses from falling out. It also comes with a waist strap you can easily stow away in one of the many pockets. The strap is a big help when I am on a bike. The bag comes with a cape for bad weather and has many smaller pockets so packing away accessories is easy.

The Camera

I am still using my good old Sony a7II which I bought in July 2016. I know that a a7rIII would be a much nicer camera but that doesn’t make the a7II a bad camera for my needs. I rarely actually feel limited by it so spending 1500€ to upgrade doesn’t seem to be that smart an idea. That doesn’t mean that I am tempted to upgrade.

Sony FE List – a new tool

After a significant amount of work I am a little proud to present you the complete Sony FE list. The idea was to create a tool which makes it quick to look up and compare the specifications of every fullframe E-mount lens with CPU. You can reach it quickly at list.philllipreeve.net.

The list isn’t in it’s final form but it felt like it was time let it into the wild. If you have any suggestions on how to improve it or spot a mistake please leave a comment.

As always: Sharing the list is much appreciated :).

Versions

MC100f3p5Macro-3
the lens fully extended

Minolta made three versions of the lens which share the optical design

  1. The Minolta MC MACRO ROKKOR-QE 100mm 1:3.5 was introduced in 1972 and has a metal focusing ring with 550g it is a bit lighter than later versions.
  2. The Minolta MC MACRO ROKKOR (QE) 100mm 1:3.5 was introduced in 1973 and it has a rubberized focusing ring.
  3. The Minolta Minolta MD MACRO ROKKOR 100mm 1:3.5 is the version shown in my pictures.

The differences between the different versions are minor and only cosmetically. Only if you plan to use the lens on a younger Minolta film camera the MD version has  some advantages.

For more technical details visit the Minolta SR lens index.

Build quality and handling

MC100f3p5Macro
with the lens hood

Builts quality is excellent, everything is made from high quality metals and feels very solid.

The focusing ring travels around 220° from 45cm to 1m and a further 60° to infinity. The focusing has just the right amount of resistance and is a joy to use. It is a bit hard to focus the lens at longer distances because the focus throw is quite short at distances above 1.5m.

The aperture ring has full stops from f/5.6 to f/16 and no stop from f/3.5 to f/5.6 and f/16 to f/22.

The lens is quite large for a little camera like the Sony Alpha 7 and I prefer to use a L-bracket with it but it is quite possible to use it without. The weight is centered in the middle of the lens which is good for balance.

The front lens is well protected even without the massive made from metal lens hood but because the lens is very sensitive to flare to lens hood is recommended.

Optical performance

These results are based on the use with a Sony Alpha 7.

Flare Resistance

The lens is very very sensitive to flare and this can be quite limiting at times

Bokeh

Bokeh is one of the biggest strengths of the lens.

f/3.5: very smooth outlines

 

Minolta MD Macro Rokkor 100mm 1:3.5
f/5.6: still very smooth and the aperture blades are not too visible

 

Minolta MD Macro Rokkor 100mm 1:3.5
f/8: now the aperture blades are quite visible

 

Chromatic Aberrations

Lateral chromatic aberrations are almost non existent.

Axial chromatic aberrations (“bokeh fringing”) are about average.

Sharpness

Minolta_MC_100mmf3p5Macro

f/3.5 and f/5.6: Sharp in the center but midframe and corner sharpness isn’t that good.

f/8:Now the image is sharp to very sharp across the frame. A solid but not great performance.

f/11: The corners improve further

Now lets have a look at the closeup performance, I compared it to my Tokina 2.5/90 which is an excellent lens.

First the center with my Nex-5n:cornersharpnessI see an advantage for the Tokina but the difference isn’t huge.

Now I placed the same subject in the corners (back to a7):centermacroouch! I redid the test two times because I assumed that I had make a mistake but with no  better results. Based on the infinity results f/8 would probably give better results for the Minolta but you will notice diffraction.

Conclusion

This is a nice lens, the mechanical quality is great and optically it is a capable lens, the only issues I found is the bad flare resistance and below average corner performance (which isn’t that much of a problem in the field). I enjoyed using it.

What I did not enjoy was carrying it: This is a pretty big and heavy lens and I found myself often wondering  if it was worth to put it in my bag when there are other lenses which do the same or even more while being lighter.

My Tokina 2.5/90 Macro is much a more versatile lens: It is a lot smaller and a little lighter while being faster (important for portraits), not that sensitive to flare, sharper and easier to focus at longer distances.

So if you already own one or can get one cheaply I am pretty positive that you will enjoy it. But don’t spend too much on it.

Alternatives

  •  Minolta MC  2.5/100: Not a macro lens but a better portrait and landscape lens. For my everyday photography I would prefer it.
  • Tokina 2.5/90 Macro: i think this lens does everything the Minolta does a little better, the only downside is the noticeably higher price
  • Almost any manufacturer had a 4/100 Macro lens and these are usually a lot smaller and lighter than this lens. The Minolta MD 4/100 is a bit sharper but I didn’t like the focusing ring.
