      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Tested TC 1.4 with 100-400L

Recommended Posts

I've heard negative things regarding this combination. I've also read where a couple people had decent results. Someone on another forum even claimed it would still autofocus.I had to find out for myself. It arrived in the mail today. Well, it doesn't autofocus. However, I was prepared to manual focus. I tried it a couple times last week and it wasn't that bad. It's certainly going to take practice. Here are a couple tests shots from this evening. Until I get more experienced, I'll definitely have less keepers. I was quite pleased the way these 2 turned out. On each of them, I cropped out about 65%. Would this be considered a 2/3 crop or 1/3 crop? This has always confused me. Anyway, I retained about 1/3.

The oriole was shot handheld at 560mm at 1/125 sec.

Wow Mike! That's very good! Hand held!? Yikes. You've got very steady hands! Looks great!

Here's what I copied from another site post about the auto focusing on the extenders...

I picked up a Kenko 1.4 TC for my Nikon because I had heard that the autofocus would work. And the autofocus works but it is quite a bit slower and it only focuses well in bright light. Nice work X. I think you'll like the combo. I'm waiting for the Sigma 150-500 OS to finally hit the shores so I can see the reviews and decide if that is the route that I want to go.

It was the Kenko that I purchased. After rereading the post on another forum, I see now that it was a different model Kenko that the user stated still offered AF with this lens. However, he also said the AF was slow and did a lot of searching. In that case, I think I'd be better off learning to manual focus. It's just another aspect to try and master. whistle The TC is not something I'll probably use a lot, but at least it's there for when I need it.

Mike, these are nice quality with the TC.

The best TCs will only autofocus on the 100-400 if you have a "1" series Canon body, because that series will autofocus a lens/TC combo with a max aperture of f8. All other Canon bodies will only autofocus lens/TC combos with max apertures of f5.6.

It's a matter of what the TC allows the lens to report to the camera. All top TCs fully report aperture to the camera, so the topline Kenko and the Canon TCs tell it like it is. Some lesser quality Kenko and Sigma and Tamron TCs don't report aperture to the camera, so the non "1" series bodies will autofocus the combo. But since that zoom can't afford the loss of IQ that comes with a TC (except in very good light, where I've gotten some nicely sharp images), putting a lower-quality TC on it just to maintain autofocus will compromise IQ too much, IMO.

The topline TCs can be spoofed by putting a small piece of electrical tape over three of the electrical contacts (pins) on the TC, which keeps the TC from reporting aperture to the camera, but as said it will force the autofocus to hunt quite a bit, and my reading indicates that taping the pins causes the lens' focus motor to wear out faster.

X,you may or may not know this,but when manual focusing with the T/C,you should be able to hold your shutter button half way down and still get a focus confimation light and "beep" when it locks onto a subject.

I've never gotten the beep or the light on manual focus with that combo and a non-"1" body.

Well, I tried everything and can't get the confirmation light and beep. I reset my camera to one shot and the lens to manual focus, and still nothing. It may depend on the brand TC used. I have the Kenko.
