Long Term Review: Tamron 28-75mm f/2.8 Di III RXD

Introduction

The Tamron 2.8/28-75 Di III RXD is the first third party E-Mount autofocus zoom lens. I am excited about this lens because it defines a milestone for the E-Mount system: until now, we only had a choice between Sony’s budget line, Samyang and the other (super-)expensive Sony/Zeiss options. The three classic third party manufacturers (Sigma, Tamron, Tokina) have been very tentative in their commitment to the E-mount system, and this lens is the first one that really changes this situation. The specs of the lens look spectacular on the paper, so let’s find out about its performance in the field.

In this review I will check the performance of my own copy that I used for several months now.

Sony FE 24mm 1.4 GM on Sony A7rII

The FE 24mm 1.4 GM – also known as the first Sony lens I (Bastian) ever preordered. At Photokina some of us had a look at this lens and Jannik, Bastian and David all decided to buy it. As Bastian and Jannik have now received theirs, we are starting our rolling-review that will be steadily updated as we get to know the lens better. 

10/17/18: Rolling-Review started by Bastian
10/19/18: Janniks lens arrived, Aperture series, bokeh, flare, samples and CA updated
10/20/18: Vignetting and close up updated

10/29/18: David’s copy arrived and partly tested. Discussion of comparison with Batis 25 added. Flare with bright  sun in frame test on A7rIII added..

Carl Zeiss C-Sonnar T* 50mm f1.5 ZM: A Detailed Review

We have become used to old lens formulas being revived and sold for occasionally huge sums of money to collectors and photographers hoping to create images with a magical vintage look. All of us here have been very sceptical about this. Mostly they have been simple lenses in simple bodies with poor technical qualities being sold for more than the price of the latest and greatest glass. From one perspective the legendary C-Sonnar from Zeiss is like this. It’s a classic design dating from 1932 whose principal design goal at the time was to reduce the number of air glass surfaces because the coatings of the day were so primitive. Why do we need it now? But Zeiss bought it back in 2006 in M mount as part of the ZM series. The optical design is not much changed, but it comes with modern coatings. Many prize it for magical rendering and flattering portraiture, others think it shows that not even Zeiss is above trying to rip off nostalgic hipsters. Read on and find out who is right!

I think it came across from my review that I was quite impressed by the Voigtländer 2/65‘s performance. So when Cosina announced the 2.5/110 they had my attention and I made my interest in a review copy known immediately. For some reason though the release date has been postponed from August. I hope we don’t have to wait much longer.

Features

The Voigtlander 110mm F2.5 APO-Lanthar Macro focuses down to a magnification ratio of 1:1. Unlike the Sony FE 2.8/90 it does not focus internally so it extends a lot when focused at smaller objects. I couldn’t test the working distance at PK but it will be interesting to see how it compares to the Sony macro.

Another key-feature is the APO-correction. While other companies have used this term rather generously the 2/65 APO offers a really high degree of correction for any kind of CA so the expectation is quite high here. Conditions at PK didn’t allow for much testing of the CA-correction.

Another “feature” is that this is the longest native manual focus lens in E-mount. I think together with my 1.2/40 and the new 3.5/21 it could form a really nice three prime set which covers almost any application I would have for it from landscape over macro to portrait. If your focus is on portraits you will almost certainly be better served by the mighty GM 1.4/85 and eye-AF. But if you like to take an occasional portrait while your focus is on other applications and you enjoy manual focus this lens might work very well for you. At least that is what I am hoping for.

Handling

Voigtlander 2/65 besides 2.5/110

At Photokina I could handle a copy and take some images. I was positively surprised to note that the 110mm Macro is just 9mm longer than the 65mm. This is possible because while the 65’s front element is deeply recessed the 110mm’s is not. Another advantage is a more reasonable filter size of 58mm. This is shared by most other Voigtlanders.

I can’t say that much about the handling: The focus ring felt nice. I didn’t use it enough to notice how it balances. The aperture ring has moved from the front to the back which one will get used to. So it most likely will be what one has come to expect from a modern Voigtlander lens which is a very pleasant to use lens.

Optical performance

Again I didn’t learn a lot from the short usage at PK. An exhausting fair where you are constantly bombarded by information and sounds isn’t a good testing ground. You can find my test images in this set. They were handheld and didn’t show anything unexpected.

One aspect I looked at was bokeh and cat-eyes. This is the full image and out of focus highlights look pretty smooth and not defined. Cat-eyes are pronounced though.

I also don’t see any onion rings which is good news.

Conclusion

I didn’t learn much about the CV 2.5/110 APO at Pk but I didn’t learn anything negative either. I look forward to either reviewing it myself or reading David’s review, depending who gets one first. I think it could find a constant place in my kit.

NiSi 75mm f/0.95 FE prototype and Cine lenses: Photokina Recap Part 2

Most people know NiSi as a manufacturer of high quality optical filters for cameras and cine lenses. In 2017 they introduced a whole line of professional cine lenses and now we can have an exclusive first look at their first camera lens, a 75mm f/0.95.

75mm f/0.95 FE prototype

Disclaimer: this lens is an early stage prototype. Housing, coatings and polishing of the elements are not comparable to the final production model. Nevertheless we are allowed to show a few pictures to give you an opinion on the bokeh rendering of this lens. Since I am a NiSi ambassador we got an exclusive sneak peak at this lens.
