Fujifilm X-T1 Has Pro Appeal and Fits Modern Needs |
Stan Sholik

During continuous high-speed shooting, the X-T1 can not only track the subject in focus, it can also adjust exposure as long as its central phase detection pixels are kept on the subject. For a subject moving toward the camera at slow-to-medium speed, this works extremely well. But with a subject moving across the frame or approaching very quickly, the live view can’t refresh fast enough between captures, making it difficult to keep the subject in the frame. Unless you’re trying to shoot a fast-action sporting event, as I was, you’ll probably never notice this. Strangely, the one place where you notice a serious time delay is when you wake the camera from sleep; you have to press and hold the release button partway down for a second or more, which takes some getting used to. Or, since it’s ready to shoot almost instantly when you turn it on, you can turn the camera off between captures. There are lots of neat tricks in the camera, so many and some so different from digital SLR options that you’ll need to spend time with the manual discovering the best set of options for your work. For example, the default setting displays the image you’ve just taken in the ELV, which I found disconcerting when I was shooting studio portraits. There are options for displaying the image continuously, for 1.5 or 0.5 seconds, or no display at all after shooting…..

The Great Mirrorless Camera Autofocus Shootout!
(GH4, X-T1, A6000, E-M1) | TheCameraStoreTV

It seems like every 13 minutes, another mirrorless camera is announced that promises the ‘World’s Fastest Autofocus’. We decided to cut through all the hype and pit the fastest mirrorless cameras against each other, and we threw in a Nikon D4S, just to make it interesting. To really put these cameras through a stress test we went to Wildrose Motocross Park with a Fuji X-T1, Sony A6000, Olympus OMD E-M1 and Panasonic GH4!

Fuji Xt1 autofocus speed | Nick Lukey

Given the number of questions asked about the speed of focus and frame rate of the new Fuji Xt1, yesterday I had an ideal opportunity to try this, and find out for myself how the camera coped with fast moving action or in this case wildlife. The settings I used were Capture rate set to CH/Auto ISO/ AF set to release priority/ Focus mode set to AFC/Face detect off/High performance off. Fortunately for me I chose a place where flying bird action is pretty constant throughout the day. A pair of Greylag geese spotted some feeding going on and flew across the lake for a look. Using the 55-200 zoom I aquired focus and hit the shutter, I shot 10 frames in total and only the last 2 frames showed oof, due to losing focus as the birds dropped into the water. Pretty amazed at this set, given the 55-200 is not the easiest lens to work with. The tracking works a treat. It was fortunate I guess  that the 2 birds stayed at a similar distance to each other. Hope you find some interest in this wee test…..

Fuji X-T1 review #5: face detect autofocus | Laurence Kim

I was really interested in the face detection capabilities of the X-T1 because, if properly executed, this could be a game changer.  As I reported here, the single shot autofocus works great, but with the caveat that changing the autofocus points is a pain.  If face-detection worked well, that would enable me to shoot portraits without having to recompose or change focus points at all. Sweet! So here is my first test. I took a doll and positioned it directly facing the camera.  I shot using the Fuji X 35mm f1.4 lens @ f1.4.  I needed a shallow depth of field to test the accuracy of the focus. I took 9 shots, positioning the doll’s face on each of the 9 sections of the viewfinder grid……

AF setup for the Fujifilm X-T1 | Nikon Glass


As strange as it may sound, one of the big reasons I fell in love with the X-T1 is its face detection capabilities, it’s so bloody accurate (for the majority of times). And what I mean by “accurate” is that when the camera actually focuses on my subject, it places the line of precise focusing right on the nearest eyeball! With the XF 23mm f/1.4 wide open, and when it focuses, its spot on! Of course there is my small print: “majority of times” that also needs to be explained. I may shoot 30-40 shots of a kid playing in a matter of a minute or two, and I may have only 4-5 shots that are out of focus – that’s a great success rate. This doesn’t mean you will get the same results, what it means is that the camera and lens combo ARE capable of such results depending on various factors such as lighting conditions and the photographers experience. With the XF 18-55mm I get faster acquisition, similar accuracy (helped by the larger DOF) and slightly more misses…….

Fuji X-E2 AF Settings | Stanley Leary

There is a learning curve with every new camera I get. Changing to another brand increases the learning curve a great deal. Auto Focus with the Fuji X-E2 has been a challenge for me due to the learning how the camera works the best. This was true with me learning all the settings for my Nikon D4. When shooting sports I used a totally different AF settings than for normal photojournalistic shooting that I normally am doing with storytelling style I use. This is what I am finding to work best for me for now for photojournalism style of shooting. First go to the shooting menu and go to the [camera 4] part of the menu. The top 4 menu items in that submenu all deal with AF……

Fujifilm X-E1 & X-E2 Autofocus Speed Testing /
Continuous Shooting Writing Testing | Nagi Usano

It takes 3.5 seconds on X-E1 and 1.5 seconds on X-E2 when I take 3 exposure bracketed images (FINE+RAW). A really impressive upgrade IMO. Firmwares are all latest version (XF35 with ver. 3.10)

You think Fuji X-Pro1 has slow or bad Autofocus, No it hasn’t, you just
have to learn how to shoot with it properly! | Jan Oscarsson

Bold statement? I don’t think so. Ok, first off, I know that the Fuji X-Pro1 and the rest of the X-serie cameras don’t behave like a Nikon D4 with top of the line Nikkor lenses! How do I know? Because I shoot Nikon D4 with top of the line Nikkor lenses daily. I love my Nikon cameras, truly love them. They are, without a doubt, the best cameras on the market today for what I shoot. There are of course photographers that may require higher resolution from their cameras but I don’t have the need for more megapixels. On my Epson printer I print large images, 44 inches (111 cm) on the short side from my Nikon D3 and D4 files. No problem at all. The only thing that bothers me with my Nikon gear is the weight and bulk of the system, don’t get me wrong, I still love shooting with the Nikon gear but after a 12 hour day I’m not so much in love with carrying it around. So this summer I started to look for something with a smaller footprint and Fuji Sweden kindly lent me the Fuji X-Pro1 and a set of lenses. For a month I shot with the Fuji gear and starting out I had to learn how to shoot with it as the shooting experience of the X-pro1 is nothing like the D4. Not bad just different. Actually I had the X-pro on loan twice, first a week or two in the beginning of the summer. This was before the most recent firmware update was released, and during that time I didn’t really have time to shoot much with it. I mostly fiddled around with it at home shooting the family, so I sent it back to Fuji and was promised to get it back in the start of August. The second time I received the camera and lenses I had already planned lot’s of cool stuff to shoot with it. So for about 4-5 weeks I shot pretty much everything I usually shoot whit my Nikon gear. This time the most recent firmware was installed in both the X-Pro1 and lenses…..

The trinity: Fujifilm X-Pro1 vs. X-E1 vs. X100 (Part 2) – Autofocus |
Alexander Sasha Starcevic

It took a while for my second post in my comparison. The last couple of days have been busy. I’ve had the chance to shoot the three cameras at some social events here and there – running into many low-light situations. So my next point of comparison is:

Autofocus:
I love the way all three cameras look and handle with all those external controls. And I love the excellent lenses – particularly the Fujinon 35mm 1.4. However, I am again and again frustrated by the performance of the autofocus. From my experience, there is no difference between the Fujifilm X-E1 and the X-Pro1 in terms of autofocus performance with the latest firmware on both cameras. Similar findings have been made elsewhere. Autofocus struggles in low light and with backlit subjects. I came from using manual lenses on a Sony Nex-7, so I am not a “spoiled” DLSR-user, but I somehow feel I am missing much more shots with the Fujifilm X-Pro1 and X-E1 than with manual focussing on the Nex-7 (using focus peaking). I had several situations where the AF (slowly) hunted and my subjects were getting impatient. Of course I am really talking low-light here – shooting around ISO 1600 to 6400 with the lens at 1.4. Quite surprisingly, my impression is that the Fujifilm X100 actually seems to struggle less with autofocus than the other cameras (comparing those with the 35mm 1.4). Maybe the reason is just that the X100 needs to move less glass, so hunting is possibly quicker. Nevertheless, I felt less frustrated with the X100 than with the other two cameras. I would be very interested hearing other peoples thoughts on this.

From the point of view of autofocus performance, I would definitely keep the X100, because the main purpose of that camera (to me) is that it can always with me. For such a camera, I don’t expect lightning fast AF performance. However, I would expect a little more from the X-Pro1 and the X-E1.

Autofocus for me is really the one reason that sometimes makes me doubt, whether switching to Fujifilm X system was really the right decision, considering that a small DSLR (e.g. Pentax K-5 II) would just give me much more reliable autofocus. Autofocus is perfectly OK if you shoot outdoors and shoot mainly static or slowly moving subjects. So for one part of my photography this is perfectly OK. However, shooting my children outside, at home or at events is currently another big part of my photography. So I would really like to own a main camera system that can cover both needs……
