review: Zeiss Otus 85mm f/1.4  vs  Canon and Nikon

Even when taking photography only slightly seriously, you’ll have come up against the legendary name, Zeiss. Renowned for innovations in optical designs that helped shape the history of photography, the Zeiss brand name is also synonymous with precision engineered lenses and impeccable attention to build quality. With all that behind them, Zeiss has released a new range called Otus. The first lens is a Zeiss Otus 55mm f/1.4 (vendor) which Zeiss describes with phrases such as “the absolute measure of perfection” and “unrivaled performance”. Knowing Zeiss, this won’t be hyperbole, but a straight-forward assessment.

With their 55m lens described as the best standard lens available, I was really curious about the new 85mm Otus lens released. Really, the description on Zeiss’ website of the Zeiss Otus 85mm f/1.4 (vendor), will send a tingle down the spine of any gear-head / aficionado. For example: “The optical correction of the Otus 1.4/85 completely eliminates almost all possible forms of aberration.”

Now, those of you who regularly follow the Tangents blog, will know that I have a fondness for the 85mm optics – the best lens to change your portrait photography. So when I had the opportunity to try out a loaner copy of “the best short tele lens in the world”, I was very curious to see how this lens would perform.

– Zeiss Otus 85mm f/1.4 (for Nikon)  (vendor)

Taking this lens out of the box is an event in itself. It’s built like a tank. A luxury tank. It is heavy and feels and looks like a top-quality lens. There’s no doubting when you hold this in your hand.

To make it more interesting, I decided to compare it with two of its closest competitors, the Canon 85mm f/1.2L II (vendor), and the Nikon AF-S 85mm f/1.4G (vendor). I used the Zeiss Otus on a Canon 6D (vendor), along with the Canon 85mm lens. The Nikon lens was on the Nikon D750 (vendor). With the cameras having similar resolution, it would be a fairly equal comparison.

review: high-ISO performance – Nikon 750 vs Nikon D4S / D4 / D810 / D610

With the initial quick test of the Nikon D750 high-ISO noise performance, I was quite impressed. But it really is only in comparison to other cameras that we can see how good it is. With that, I took 5 of the current full-frame Nikon DSLRs to compare them against each other to see their high-ISO noise.

The Nikon D4s (vendor) is currently the high-ISO king, so it was specifically interesting to see how the 24 megapixel Nikon D750 (vendor) would compare. If you’re in a hurry and don’t want to wait until the end of this review, then here’s the good news: to my eye, the D750 is comparable to the D4S in terms of high-ISO noise. Maybe even a squeak better! But you don’t have to take my word for it, there are RAW files you can dowload and check for yourself.

review: Sigma 50mm f/1.4 ART lens

The moment you hold the Sigma 50mm f/1.4 ART lens (vendor) in your hand, you know it is a serious lens. It is hefty. It feels like quality. It just feels like they took craftsman-like care in designing and manufacturing this lens!

Sigma has somehow turned their image around from being just a third-party lens-manufacturer, to a company that needs to be taken seriously for quality optics. It started with the Sigma 35mm f/1.4 ART lens, which proved to be a spectacular lens! (Here is my review: Sigma 35mm f/1.4 DG HMS art lens.)

There’s been an incredible buzz around this lens – the Sigma 50mm f/1.4 ART lens. The initial reviews are unanimously impressed with this lens’ optical performance. Right up there with the very best. When the 50mm lens was first announced the rumored price was around $1,500 but with its official release, it came in at a relatively moderate $949.00 … but for that price, we’d expect a truly quality optic.

The good news – it really is all that! I would heartily recommend this lens.

using the Profoto B1 portable flash at a wedding

With wedding photography, there are nearly inevitably time-constraints. It is therefore imperative that you, as the wedding photographer, are able to keep everything running as smoothly as possible on your side. Which implies that it is important that you (and your equipment) are adaptable. And it is also hugely important that your gear is easy to set up, and very reliable.

Karissa and Rory’s wedding was the first where I pulled out the Profoto B1 battery powered flash (vendor). I’m even more impressed with it now, than I was when I first tested it for my review: Profoto B1 500 AirTTL battery powered flash.  (And if you’d like to buy my previous AcuteB 600R kit, let me know.)

When using additional lighting, you ideally need a few things from your lights:
power! 
– and yet, a delicateness to the light when necessary.
speed of use is essential.

At 500Ws, the Profoto B1 dumps sunlight-levels of light, but you can pull it down 8 stops, to where the light can be used in subtle ways.

With off-camera flash, I’m mostly working with a specific distance, and then manual flash makes sense. The  Profoto B1 (vendor) offers TTL as well, and this might seem superfluous to some. But it really makes it easier and faster to get to correct exposure. You can do an initial exposure via the TTL mode, and then switch to Manual if your exposure is correct. This gives you the speed of TTL flash, and the consistency of Manual flash.

Here are more images from this wedding, with examples shot with the Profoto B1, as well as other images using various types of light ….

Nikon D750 – high-ISO noise performance

The two things everyone is most curious about with the new Nikon D750 (vendor), is the auto-focus performance and the high-ISO noise performance. Here’s a quick preview of what the D750 does at higher ISO settings. Specifically, 3200 ISO and 6400 ISO.

To put the Nikon D750 (vendor) through its paces for the (upcoming) review of this camera, I met up with NYC model, Glass Olive for a photo session. In a restaurant we visited, I used the Sigma 50mm f/1.4 DG (for Nikon) (vendor) at f/1.4 and then tried sequences of images at 3200 ISO and 6400 ISO. Here are two more images, and a 100% crop of each so you can see what the noise pattern looks like.

A few things to keep in mind when looking at the two images:

  • the RAW converters haven’t been updated yet for this brand-new camera, so we are looking at the embedded JPG (at full resolution) that I extracted from the RAW file. So this is the straight-out-of-camera JPG with a slight detour. These could very well be improved upon when adjusting the RAW file.
  • I kept the JPG settings to the defaults, but these were shot in Vivid picture mode. So it looks quite punchy directly out of camera.
    In Vivid picture mode, the Sharpening is set to the middle value: 4.00
    The Clarity was set to +1.00
    (The WB was set to Auto 1)
  • looking at 100% crops give you an idea of the high-ISO noise, which helps with comparison. But, it is not how the image will print. We are looking at a 24 megapixel image. It’s huge. By the time you print it to smaller sizes, the noise is much less pronounced.

portrait & headshot photography: studio lighting tools – Westcott Eyelighter

With portrait lighting for head shots, there are so many configurations – all the way from dramatic lighting, to very even light – but always keeping in mind that the lighting needs to look flattering. It is all in how we balance the various lights, and how we add fill-light.

Westcott has released a curved reflector, the Eye-lighter (vendor), and it is quite versatile:

review: Canon EF 16-35mm f/4L IS — Canon redeems itself

The title there is quite an exclamation – Canon redeems itself. And you may well wonder what Canon had to redeem itself for. Well, my experience with Canon over the years has been a clouded one. A number of years back I moved back to Nikon again when I couldn’t handle the Canon 24-70mm f2.8L going out of calibration every so often. Then, there was the untrustworthy AF performance of the Canon 1D mark III. In fact, I’m still waiting for Canon to send me an apology note for that camera. In fact, for all three bodies that I owned.

But I digress … we’re talking about Canon wide-angle zooms. The final straw for me with regards to Canon, was when I had worked through five copies of the Canon 16-35mm f/2.8 II and all five copies had issues and were soft to the edges. It’s all detailed in this post: Canon and Nikon. Then, I finally got to use the Nikon 14-24mm f/2.8G (vendor), and my struggles with soft Canon wide-angle zooms were over. I finally had a wide-angle lens that was razor sharp to the edges. And a zoom, to boot!

So with that, I was done. I had given up on Canon ever producing a wide-angle zoom that could perform. Sharp to the edges. No optical smearing. Just do what it is supposed to do – be a wide-angle zoom lens. Something the Nikon 14-24 f/2.8G excelled at. And that is something the Canon 17-40mm f/4L and the Canon 16-35mm f/2.L II didn’t quite do as well.

Then the Canon EF 16-35mm f/4L IS (vendor) arrived, and I was curious. Could this finally be? And yes, Canon has redeemed itself. Finally, here is a Canon wide-angle zoom that is an excellent performer. You know, worthy of that red stripe.

review: high-ISO performance Nikon D4S vs D4 / D3s / D610 / D700

Judging image quality between different cameras, is most often quite subjective when we have equal glass with each camera. The reason for this is that the pixel count has an effect. For example, how do you compare the high-ISO noise performance of the 36 megapixel D800 vs the 12 megapixel D3? You can’t just simply zoom in to 100% and go by that. You would have to print to a specific size, or at least down-size the D800 image to 12 megapixels to fairly evaluate the images. So there’s a bit of a murky area here in fairly comparing cameras of different sensor sizes.

We now have a new King of awesomely awesome high-ISO noise performance – the Nikon D4s (vendor). I posted one image in the review of the Nikon D4S auto-focus / AF performance, which was shot at 8000 ISO. In my opinion it looked remarkable.

So how does the Nikon D4s high-ISO noise compare to the other Nikon cameras? Well, I chickened out here. Instead of doing comparison photos and then processing them the same, and figuring out some kind of baseline in terms of image size, etc etc … I wimped out. I’m giving you the high-ISO RAW files, shot from 800 ISO and up, for various cameras. Download them from that link via a right-click and save-as.

review: Fuji XT-1 camera

Pentax used to have a slogan that said simply, ‘Just hold a Pentax’. Such was their confidence that they could win you over with a Pentax SLR. Just hold it, feel it and you will already like it. A lot! For me, that mantle could be placed on Fuji these days. With the X-series cameras, they’ve built up a range of cameras that are very appealing. They look good. They feel good … and they give stunning results.

Yes, I am somewhat of a Fuji fanboy. But then, I love quality products. I’m a fan of that. My walkabout camera is the sexy Fuji X100s that I carry with me every where in my shoulder bag. I’ve been following the releases of every Fuji camera since the first X100. It was obvious Fuji was on a mission then.

And now we have the Fuji XT-1 – the latest in the Fuji X series. I immediately loved the camera. With this review of the Fuji XT-1 (vendor), I want to give an impression of the actual user experience.

review: Nikon D4S – auto-focus / AF performance

The Nikon D4s (vendor) updates the already-awesome Nikon D4. The short summary lists some improvements, which while they may appear incremental, overall make for a solid new release by Nikon:
– a newly designed sensor, offering better high-ISO performance,
– an additional AF mode has been added – Group Area AF – for more accurate subject tracking,
– 11 fps continuous shooting with continuous AE/AF (compared to the 10 fps of the D4)
– ‘small’ Raw size of 8 Mpx,
– 1080/60p video
– faster processing with the new Expeed 4 processor
– improved battery performance,
– Multi-CAM 3500FX Autofocus Sensor Module with “thoroughly recalibrated AF algorithms”

For this review, I want to highlight the auto-focus performance. AF speed and accuracy is in a way subjective. There’s no numerical value we can attach to it that will tell us in discrete steps how much better the “thoroughly recalibrated AF algorithms” with the new AF sensor module will improve on the D4 camera.

My friend Yasmeen Anderson specializes as a fitness portrait photographer in NJ, and I asked if I could tag along on some of her shoots. With this photo session of actor / model Joe Monbleau, we shot in a colorful urban area in NJ. Joe tirelessly sprinted and bounced and jumped for numerous sequences. Enough time for me to fire off the D4S and see how it perform in grabbing crisply sharp images of someone moving fast.

And yes, I am very impressed. The Nikon D4S is noticeably more responsive with auto-focus on moving subjects. I’ll blame those “thoroughly recalibrated AF algorithms” in the new AF sensor.
