Images taken with a 2x converter
Apr 21, 2024 04:09:20 #
I decided to post these images because of recent discussions about whether or not people should use 2x extenders. I know these are birds, but putting them in the bird subsection will prevent the converter discussion.
The photos are taken with a Nikon 400f2.8s lens. The built in 1.4 converter is being used and coupled with a 2x converter. The wren also has a 5mm extension tube for closer focus.
So, the question is are these photos sharp enough, or should people not use the converters and attempt to gain the extra reach by cropping. I believe that any loss of image quality from using the converter is more than offset by the additional reach and the ability to come closer to filling the frame, but I thought it would be interesting to see where any discussion would go. Those of you who believe that no one should use teleconverters, go ahead and have your say. The photos will be posted in the first reply.

If you are happy with the results, use them (unless you have clients, then it will depend if they are happy)
Also a computer screen will not show enough detail for us to be able to decide from your examples

Well neither is very sharp but it’s hard to tell if it’s due to the TC without something to compare it to.

Cameras and lenses for the most part are better than what we use to display the results. The new AI post treatment make our old 2000 low resolution photos new and modern looking .. They will look good be it a print or 50" TV... also the eye/mind perception is quite limited.... Oh, lit us not forget the lighting on any print be it a 4x6 inch or Billboard.

People should use convertors if they have a good convertor/lens combo and know how to use them.

First, you posted in the wrong section.
Second, no teleconverter ever produced improves image sharpness.
Third, combining teleconverter's really makes sharpness suffer, as seen in your images.
Forth, I use a 600mm f4 without any converter on a full frame mirrorless camera that I use for my wildlife photography.
Fifth, I never use teleconverter's because of the reasons I have given.
Sixth, Good luck and keep on shooting until the end.

Nice results. I don't have a 2x, but I have used something under 2x, and it works fine. It's not very often that it's necessary to zoom in 200%. If it looks good as is, then it's good.

Depends on what you need out of the photo, IMHO. Obviously the photo will most likely be softer. First photo is too soft to be used as anything but a seen this bird in this area photo. Second isn't to bad showing its habitat if your pixel peeping or plan on blowing it up for a larger print. Try running it thew software like Topaz AI Sharpen at all?

They are sharp enough for compressed web viewing which is what we are doing. Are they sharp enough for a 20x30 print, depends on who is paying. If all you are going to do with this combination is post on the web, have at it.

I don't know if you tried any of the fancy sharpening filters out there. Topaz Sharpen AI being one of them.

It mostly depends on the quality of the lens and the f-stop speed of the lens and the ISO performance of the camera you are using. The other part is the light level you are using them with and the pixel density of the sensor.
Lower light levels and higher pixel densities favor cropping with AI pixel enlargement. And then, there is the loss of AF speed with converter .....also favoring cropping
Yes, I have used the Canon 2XII with the 300 2.8 and the 2X III with the 400 f4 DO.....
