Crop Sensor camera vs. Full Frame with an extender questions (Page 2): Yes, there's not much difference in the resolution between the 5DIV and the 90D but the 90D uses newer technology...

That’s a well taken point although not sure that I’d trade the 2.1 extra MP of the 90D for the larger pixels of the 5D4 as the cropping makes any noise more noticeable and the 5D4 is better in that respect. The 90D’s 32 MP vs the 80D’s 24 is certainly substantial however.

Yes, there's not much difference in the resolution between the 5DIV and the 90D but the 90D uses newer technology and the DIGIC 8 processor vs the DIGIC 6+ processor.
I own all three cameras and when I go on a photo safari I usually take a 5DIV with EF 24-105L II attached and a 90D with EF 100-400L II & 1.4X III attached.

It's not as stupid as you think, if you take the time to really think about it, which obviously you did not. The 90D has higher resolution than both the 5DIV and 80D making it a far better candidate for cropping. Shame on you for being so narrow minded.

That’s not what he was asking about it’s what he is using now. He wasn’t asking about a newer camera and yes you’re first comment was stupid in my opinion and uncalled for.

Personally, I would capture identical test shots with both rigs and check the results carefully to see which I liked better.

Experiment and practice with your options. It’s the only way to learn.

Yep, I used to think that if I added a crop body to my kit, it would be a 7D2 because of the rugged construction like the 5D series (and I used to own a 7D), but the 90D is so good, I believe it might be my choice now,

Hi:
I have a canon 5D m4, and a 80D. My Question is to gain more reach with my canon 100-400 11 lens would I be better off using my 5D M4 with a 1.4 111 extender or my 80D.

Thanks

A crop-sensor camera DOES NOT GIVE MORE REACH!!!!! What it does is CROP in-camera the image coming through the lens.

You can do the cropping all by yourself by using a full-frame camera and cropping when viewing and printing.

The cropped portion of the crop-camera image does have to be enlarged more to fill a given print size than the full-frame image does. This is where comparative megapixel counts comes in. That's a whole other discussion.

Don't know about your Canon equipment; however, with my 24 MP Sony A7 III (full frame) and 24 MP Sony A6100 (crop sensor) I get the best resolution with a crop sensor BUT the best low light performance with full frame.

I also have Sony's 1.4x teleconverter. I get about the same performance using in on the A7 III as I do using the crop sensor A6100; both give about the same resolution and the teleconverter reduces the A7 III's low light performance.

In my case I'd have to say... It depends.

My 80D autofocuses fine with the 100-400L plus the 1.4X at 400 but not with a 2x.

Starting with the 80D and now even into the Rebel T7i, the f/8 AF capability has been extended by Canon into EOS models beyond the 1D and 5D series. You need to get mirrorless to get AF smaller than f/8.

I think it depends. If I am correct both are around 20 MP. The 5D4 is much better in low light, so shooting with higher ISOs you will have much less noise with that than with the 80D, even though you are losing a stop with the extender. On the other hand you will get a small drop in IQ due to the extender, so in good light you might have an edge in resolution and less chromatic aberration using the 80D.

Close to my findings with Sony full frame vs. crop sensor.

I have both bodies and the extender. My 5D MIV with extender does quite well. Fully zoomed out you can only go to f8 on either body. I have used the 100-400 II and the 1.4III on both bodies and it works great. So get the extender and if you really want reach, go for the 80D. Really low light, 80D and no extender. Don’t need a lot of reach 5D MIV no extender! Hope that helped. I would never give up my 1.4 III. 5D with extender sorry don’t have an 80d at my fingertips with extender.

While the comment on upgrading the 80D may not have answered the specific question being asked, in what way do you believe it was stupid and why should he be ashamed? That was a very strong rebuke from you for an innocent comment. Whether it addressed the original question or not, it was certainly not "stupid". However, it does make me wonder why you felt the need to be so nasty and insulting about it. Would it have been so difficult for you to just say, "You're not answering the question being asked." or better still, just ignore his post altogether?

Thank you. I was going to make a similar reply. (I hadn't thought about CAPS)

I don't know why the "more reach" myth persists but I guess I see where it comes from. Yours was a good, precise answer.

What I find interesting is, he didn't bother to offer any kind of constructive response, just negativity and name calling. I offered an alternative to the 80D's lower resolution. The 90D isn't all that expensive and is a better, higher resolution camera than the 80D. I know this because I own both, and I did eventually go into greater detail when I had the time to do so. I guess RichardSM is a self appointed response police. Like buggs bunny says, ehhh, what a maroon.

The 90D definitely offers better resolution and image quality over the 7DII, but if weather sealed construction and high end auto focus and dual memory cards and, one of which is a CF card, and better buffering are high on your priority list, the older 7DII may be the better option. Personally, I like both cameras.
