crop vs full with 1.4x
Oct 18, 2018 10:21:24 #
Love to hear from those that have compared or use both. Assuming 300m on a crop sensor camera or the same 300m on a full frame camera with a 1.4x . Love to hear about image quality pros and cons and any other feedback. I should add that I do have both but before I actually play around with both set ups, I would like to hear from those that have. Do the pros outway the cons? for example using my 300m on a Canon 7dm2 (crop) vs using it on Canon 5dm4 (full) with 1.4x I realize the 1.4 and the 1.6 crop aren't the same but I'm wondering if anyone noticed quality diff, setting diff, speed diff........

First and foremost is the loss of 1 stop of light with the 5DIV with the 1.4. Now for reach, 420mm vs. 480mm and if you add the 1.4 to the 7D MKII you now have 670mm with the same light. A lot will depend how you shoot, how good are you, why, because both set ups can very well be hand held. I have the 300mm f/2.8 and a 600mm f/4.0, the 7D MKII and the 1DX MKII and shooting both lenses with the two different bodies and a 1.4 I find very little if any difference in the finished product. I will add that I prefer to shoot off a tripod and I use a video head and a cable release always when shooting the 600mm. Since you have the lens and the two bodies I don't see why you just don't do your own testing and come to your own conclusion. Is your 300mm a Canon and is it the f/2.8? Did you just acquire all this equipment and if not then why haven't you done some shooting? One other very important point, have you micro-adjusted both bodies with and without the 1.4, if not you could be wasting your time.

Your 30MP 5DIV should be capable of producing better images at every ISO, by an obvious difference, even before cropping. The 7D MKII is no slouch, but it's also reaching end-of-life for an older sensor design vs a newly released full-frame sensor. This quality difference should far outweigh the fps and cropped-factor of the 7DII. The best approach with either format sensor is to fill the frame to the extent possible based on your distance to the subject. This approach will maximize the possibilities of the final result, whether cropped or not in post, to achieve that result.

Im confused...a ff camera has no crop and you say 1.4. Also, is the lens for ff or crop.
If the lens is ff, when you put it on a crop, it will be a smaller photo (zoomed) crop x 300. 1.6 crop would appear as 480

I am assuming you are talking about a 1.4 teleconvertor, if so a crop sensor camera will do better in situations that you need the extra reach. A 1.4 teleconvertor works fairly well, but a teleconvertor will effect your light by about 1 step and may slow down your shutter speed. From my personal experience, when I am shooting sports, wildlife, or anything that I feel I will need that extra reach, I use a DX camera, I find it much easier and I like the quality of the photo better than a teleconvertor. Hopefully this helps and happy shooting.

when I say 1.4x I mean adding a 1.4 extender to the 300m.
300 + 1.4 extender on a full frame vs 300 by itself on a crop sensor camera = ??
300 + 1.4 extender on a full frame vs 300 by itself on a crop sensor camera = ??

yes, that is what I was wanting. i do plan to one day play around with this but the best tool I find is feedback from others. Thanks

I wonder! Cropped, the 5DIV no longer has a megapixel advantage over the 7DII. I suspect the pixel sizes are about the same (~1.5 times more pixels, 1.6 crop), so I'm not convinced. Surely the 1.4 TC reduces the light 1 stop on the 5DIV, a disadvantage.

My question is WHY? A crop camera crops the image "in" camera. With a full frame camera all you have to do to get that same image is to crop the image in p/p.

Sensor utilization. A crop camera does NOT crop the picture in the camera. A FF with a crop mode does, however.

But it is NOT the same. A crop camera uses ALL its pixels on an image cropped by virtue of a smaller sensor, cropping a full frame
image after the shot throws away many pixels.

Essentially a crop camera crops the image projected by a full frame lens.

A crop camera crops nothing. It is a smaller sensor than a FF camera, by it's crop factor. The crop factor is nothing more than a reference to a full frame camera. A 1.4 crop sensor photo will be 1.4 x smaller, as if zoomed in. What you see is what you get, no cropping.

Everybody thinks of it in different ways, I suppose. When I look at the following image, with the larger rectangle being full frame and the smaller rectangle being crop sensor, in my mind the crop sensor crops the image.
