Canon R7 Extender 1.4 Experience

[esp5]

Hi all. Had the r7 with rf 100-400 lens few weeks now and love it. Just wondering if anyone has and experience with this setup with the 1.4 x. Not looking to buy another lens etc just opinions and views of those that do or have used this set up
Thanks everyone

At the long end, you'll get 560mm at f/11. Good enough for sunny days. I've used the 1.4 extender on my 100-500 and the results are good, but I prefer to crop if I'm using the R5 to keep the lens and camera weight and balance manageable.

I'm going by hearsay, but believe the tele-extenders are optimized for the big white primes and less so for the zooms. Of course they work well on the zooms too, but cropping also does, and with a high-mpx body, I believe cropping will win out.

IMHO, the 1.4TC works well on the RF 100-500 on the R5 (I don't have the 100-400). On my R7, the 1.4TC further compromises the camera's AF with the RF 100-500. I suggest going to a cam store and trying it on the R7 in normal light before purchasing.

Whilst the loss of 1 stop of light when using the 1.4 extender is annoying, with todays cameras which are very good at higher ISOs i don't see it as a show stopper. I use it on the RF100-500 and find it useful when you need that bit of extra reach.

Not sure if it would work with your RF100-400 lens. Below was taken from the Canon website:

"This extender is only compatible with the following RF lenses RF 600mm F11 IS STM, RF 800mm F11 IS STM, RF 100-500mm F4.5-7.1 L IS USM. Use is not accessible with previous RF lenses. Additionally, please see the lens and/or camera body manual for full compatibility information with the Extender RF 1.4x."

I might be wrong though.

I'm seeing the Canadian site needs updating. Thanks for the share.

I too purchased an R7 along with the 100-400 in the pre Christmas John Lewis sale. I added the 1.4x TC from the Canon Store. Early days and the only test I have made with/without the TC is on planes from Heathrow at about 5000 ft, with it I can read the registration without I can't. When out birding I've left it on as usually things are a distance away but I will be trying with without on birds in the garden to see if a crop results in sharper images, as the TC isn't cheap I'd expect the TC to win over the crop. I'm more interested in how it affects the focus though compared to a Panasonic Bridge and the M50 with an EF lens I was using before the R7 is in a different league.

Check out the comments at Reddit, especially the post by gabedamien on use of the 1.4x with the 100-400mm.

There are lots more articles online about crop vs TC, and I have read a few. The conclusion is that sometimes cropping wins and at other times the TC wins. It depends on the particular lens and on shooting conditions. TCs work better on high quality lenses, and they benefit from good light.

In the end, it might be the skill of the user and technique that is more important. But for now, I'm resisting using a tripod with gimbal head for my shots.

Sometimes you want to get closer but can't because you're being watched -

Resized for web. Low light is a problem if you can't find any contrast. When the light starts getting too bad I switch to a 70-200 f4, don't need long reach in bad light.

I think that knowing your gear is really important. I use an EF100-400 with my R7 and depending on the conditions I use the 1.4TC.

I have the R7, RF 200-800 lens and the 1.4x extender. I'd say with my experience, for small and close birds in good light conditions, with the extender on, I can get tact sharp images handheld at 120% magnification on a 27" 1440p LG IPS monitor at 60-70cm distance. Keeper rate drops down to half in terms of focus, and the autofocus slows down by a noticeable margin as well. But with the bare lens in the same conditions, I can get tact sharp images at 140% magnification. So eventually when you crop in, with the extender you'll end up with a slightly larger bird at tact sharp magnification. However on the moon shots, so far without the extender I ended up with slightly more magnified sharp images. It's not a disaster but that's a thing.

I didn't see this thread. In April I decided to pull the 1.4 off the R7 and 100-500 and shoot like that for the rest of the year. Not that I can't do well with it but that move has increased my keeper rate quite a bit. I think cropping a bit too much with the 1.4 takes a detail hit quicker than without it. So it is a mixed bag there but BIF is easier I shoot that most often. More light without the TC. If I know I will shoot static subjects and know I can get close enough for minimal cropping I'll put it on. Has not happened yet.

I made that decision after Phil sent me a RAW file of a perched bird. After importing into LrC and with minimal editing I was able hit the IQ I was expecting so it was not my editing process. I find the 1.4 performs much better on the R6II and 100-500.

Interesting report, thanks.

I was on the fence about the RF 1.4x but decided to buy one before my Costa Rica trip back in March of this year. I expected there to be lots of really distant birds. As it happened, nobody in town had the 1.4x in stock and there was no time left, so I never bought it. And did pretty well in CR with the bare lens. But never knew if the 1.4x would have helped.

I used the R7 the whole time. (Had the R5 as backup.)

Lots of time has gone by and now I think I will probably not get the 1.4x.

I'm having constant focusing problems with the R7 and 100-400.
I add the 1.4 TC and more problems.
I'm shooting sunrise and sunsets so it's not light.
Is shot BIF. Sometimes good but this camera is a GREAT disappointment.

I've had zero focus issues with the 70D

 

[MSH411]

Both the Rf100-400 and R7 can be challenged with low light, add the 1.4 and the challenge will become more server. I run into the same challenge with my R6 MkII and RF24-240. As soon as I get some decent light my challenges disappear. It's stating the obvious but I rarely have any low light focusing issues with any of my 2.8 lenses. It's the nature of the beast with slower lenses.

I've recently got the 100-400, With the 1.5 and 1.6 software I'm not having many issues in good light both with the 1.4 extender at F/11 and the bare lens at F/8-9. I also use 15 Fps electronic, and I'm using daude paton's R7 sigma 150-600C settings which slows down the system abit to reduce focus hunting. Maybe that'll help.

For one thing, Your using the wrong lens. You would be better off using the EF 100-400 and adapter. Or the RF 200-800. Extenders just are problematic and not really worth using. Look a apsc like the R7 plus 800MM crop. Do you really need more reach? Also why people obsessed with 30fps. 15fps is fine. R7 not a sports camera.It replaces the 90D. I love this camera for birding and RF 100-500. Tack sharp RJ
