Rebel T4i

[zelonisv_bob]

I want to move up from my T1i.  A used T4i body is available.  Is the T4i a worthwhile upgrade, and will it do at least as well as the T1i?  I'd like the advantage of the articulating LCD viewfinder.  Thanks.

If I recall correctly, the T4i had some "USB Throughput" issues. (And shallower Image Buffer - which doesn't really impact AP Imaging.)

The T4i was rather quickly superseded by the T5i, and rather unusual for Canon the T4i was NOT continued as an Older Model (but the T3i was continued well into the introduction of the T6i).

You should consider finding a Used T5i.  Or if you can find one within your budget, go for the T6i (which has a newer Sensor with 24MP and smaller pixels - 24MP vs 17.9MP / 4.31um vs 3.72um / DXO Score 71 vs 61).

Thanks, S3igell.  I read on with the reviews of the T2i, thru the T5i .  I began to tire of the negative reviews which mentioned less-than-great imaging quality with normal use of a camera as on terrestrial targets.  I'm more interested in astro photography and so the major concerns would be about the camera's image capturing and processing with BYEOS software.  So, it looks like the T6i or T7i would be the wiser options.

If you want to use BYE for Planetary imaging, then I would suggest another camera than the T4i. Several users reported a slow USB download rate with that model. I get more expected frame rate with my T5i.

In general, I would expect the newer models to be improved. Otherwise why release a new model? The question really is are the new features and improvements of benefit for the types of astrophotography that you anticipate shooting.

The amount of processing that is performed on your images by BYE is limited to updating the metadata in the image and changing the name if the image file. The image pixels themselves are not altered. In fact you can prevent BYE from even updating the metadata by selecting the Skip Writing of EXIF Data option on the Advanced Settings dialog.

As I very recently said to S3igell, it looks like the T6i will be my choice (because of a greater number of pixels and pixel size).  Thanks for warning me about the slow download rate of the older models.

The LiveView frame rate of the T4i was much slower than both older and newer models.

Thank you, Rick.  The issue is now moot because I've purchased a Canon Rebel T6i body.

Great! Have fun with it!
