This page presents my practical experiences with close-up shots using an macro lens with the Leica M (Typ 240) in live view mode, namely the Novoflex Noflexar 35mm f/3.5 lens.

See page Close-Up Options (Live View) - Part 2: Practice I for my practical experiences with close-up lenses or achromats and extension tubes and page Close-Up Options (Live View) - Part 3: Practice II for my practical experiences with extension bellows.

See also page Close-Up Options (Live View) - Part 1: Overview for an overview of the options that you have for close-up shots when using the Leica M (Type 240) in live view mode and pages Close-Up Options (Live View) - Part 5: Samples I and Close-Up Options (Live View) - Part 6: Samples II, and Close-Up Options (Live View) - Part 7: Samples III for sample close-up photos with the Leica M (Typ 240).

Note: Page Close-Up Behavior of the M-Mount Lenses describes the close-up characteristics of the lenses when used without any close-up options.

 

Introduction

On page Close-Up Options (Live View) - Part 1: Overview, I mentioned that rangefinder camera are not well suited to close-up photography because of the parallax. With the Leica M (Typ 240), however, this has changed, because Leica added live view to the camera. With respect to close-up/macro photos, in live view mode the M behaves like a system camera (or like a DSLR) and can use all the techniques that these can use: close-up lenses, extension tubes, extension bellows, and macro lenses. On that page, I provide an overview of the options that you have for close-up shots when using the Leica M (Type 240) in live view mode. On this page and two other pages (see on top of the page), I would like to present my practical experiences in this domain, which are, of course, of anecdotic nature.

Because of the length of this page, I prepared three separate pages for presenting sample close-up photos (see on top of the page)

Calculating Magnification

From dkpeterborough (l-camera-forum) I adopt the way how magnification is calculated:

Below, I will use this formula for calculating the achievable magnification under various conditions.

 

Novoflex Noflexar 35mm f/3.5 Macro Lens

The Lens Alone...

I bought the Novoflex Noflexar 35mm f/3.5 macro lens at the end of January 2017. My sample has an with M42 mount (COWEIT) and the serial number 355941. I do not know which production year this points to, but I read that the lens was manufactured in the 1960s (it was manufactured by Staeble who sold a more or less identical lens).

Adapters...

Since my Novoflex Noflexar 35mm f/3.5 lens has an M42 screw mount, I need an adapter to attach it to my Leica M (Typ 240). I bought the Novoflex LEM/CO adapter, and I was able to attach it to the lens without problems, though there is some slack.

Luckily, the Quenox Extension Tube for Leica M offers the option to achieve even higher magnifications by extending the lens barrel for another 1 cm. I cover this aspect on this page as well (see below).

So, this is my "macro set" for the Leica M (Typ 240) when I use a macro lens:

Using the Novoflex Noflexar 35mm f/3.5 Macro Lens as a Close-Up Lens

Some Specialties

According to Novoflex, the Novoflex Noflexar 35mm f/3.5 lens serves two purposes: (1) It is a 35 mm lens that offers more field of view than a normal lens (50 mm), (2) it serves as a macro lens with magnifications of up to 1:2 without any other tools - the lens barrel can simply be extended like extension tubes via four click-stop positions. Fine tuning seems to be possible by turning the distance ring (the technical data sheet speaks of a "helical focusing mount"...). Larger magnifications are possible using extension tubes or bellows and/or by reversing the lens. I tested the Quenox Extension Tube for Leica M (1 cm) with the lens, and it seems to work well. Maximum magnification was, however, still below 1:1 with this 1 cm extension tube (lens not reversed).

From 1:1 or larger, Novoflex recommends to reverse the lens; they supplied respective rings for the filter thread (UMCO (M42), UMEX (Exakta), LEIUM (Leica)), but I do not know whether these are still available. They also state that the lens barrel acts as a lens hood in this case.

The table below describes the use of the lens as a macro lens and summarizes, which magnifications can be achieved with which lens setting without and with an additional Quenox Extension Ring. I do not present photos that "prove" my numbers (so there are no "ruler photos" here...), because in the end, I am probably the only person who will use this data... Anyway, this table should be taken with a grain of salt and be used only as an orientation aid.

4 82 65 1:2.3 1:1.8 51 43 1:1.4 1:1.2

*) MiOW = Minimum object width

As you can see from the table, there is some overlap between the ranges that the different click-stops cover when you turn the helical distance ring. A magnification of 1:2 can only be achieved when the distance ring is set to the closest distance (or close to it) and the lens is extended four click-stops (without extension ring). The latter costs one f-stop exposure-wise. With the Quenox extension ring (1 cm), one can come fairly close to a magnification of 1:1 and loses probably about two f-stops.

 

Summary and Conclusions

It looks like I have started an interesting journey with buying the Novoflex Noflexar 35mm f/3.5 macro lens. Taking close-up shots with it is fun and much easier than using close-up lenses. Adding an extension tube adds some complexity, but allows for more magnification. The lens is very prone to flare and creates "sun rings" when wider open, though. At f/8 and more, this improves considerably. It alos cannot be used for objects at infinity (or large distances). All in all, I am quite impressed with what is possible with this lens - despite all its limitations...

In the end, this lens is the most straighforward solution for taking close-up shots with the Leica M (Typ 240) - at least for me...

A smaller set of sample photos taken with the Novoflex Noflexar 35mm f/3.5 macro lens is presented on page Close-Up Options (Live View) - Part 7: Samples III.

There are also quite a few sample photos on this site that I took with this lens - so see for yourself:
