Have you tried a 6D for daytime or astrophotography? So I'll answer your question with a question. Widefield photography is quite more enjoyable with a full frame rather than with a cropped sensor. I'm not sure if you've had your hands on a 6D camera and tried imaging with it, but I am certain you would see the difference and fall in love with it.īesides, a full frame sensor has better 'sky coverage' which is also a plus when appropriate lenses and telescopes are used. There is a reason why the 6D is still among the most popular DSLR cameras for astrophotography. I don't have any issues with my computers handling thousands of images. Having such an amazing camera with the sensor that the 6D has, I would never even think of running it at ISO less than 800 for astrophotography unless the ambient temperature is very high. It is up to one's preference of course if they choose to use lower ISO with cropped Canon cameras but the common wisdom tells us that they perform well at ISO 800 and some at ISO 1600. I base my conclusions on my experience with any equipment. Honestly I never fully trust online sources and the numbers they provide. And I don't think I talk as a salesman, the company I run does a lot of behind the scenes work on providing services and cameras for free to the folks that can't afford to buy even a used camera. I prefer to avoid any drama around numbers and treat AP as a hobby that I enjoy. I apologize if my post has insulted you in any way. Could you please answer my question? What it it, that makes FF an update? Thank you!Įdited by the Elf, 10 January 2022 - 04:41 AM. I also asked you to tell us why FF is an update but your answer is that you tested lenses. Have you got anything like this for 600D vs. If you read my article linked in #2 you can find a side by side comparison of the same object in the same night, swapping the cameras several times to make it absolutely comparable. Could you elaborate on "big step", please? In terms of what? Especially resolution and tight stars are not so much a feature of the camera but the optics and tracking. Image quality has many dimensions like resolution, the lack of microlens artifacts, contrast, good color, whatever that may be, tight stars, etc. I'd like to see some hard numbers rather than a vague statement. What overall performance? In AP we talk about QE, DR, RN, and full well depth. I can't tell if it is possible to shoot longer subs with the 6D if that is an important point to the OP.Īsanmax, don't get me wrong, but "The 6D is a big step forward in terms of overall performance and image quality." is salesman talk. It the same over all number of photons is collected in more subs on a smaller sensor with a shorter focal length or with less subs on a larger sensor using a longer focal length does not make a difference as long as signal is far higher than read noise. In fact it is possible to achieve the same quality with a FF and a crop sensor if the optics is matched in terms of image circle and resolution. Of course the larger full well outperforms the smaller sensors so that the resulting DR is still higher. Again this tells me it is a good performer at high ISO for sports and nightscape. Looking at the read noise chart the 6D performs worse at low ISO. For AP only all the bells and whistles are not important. For someone shooting with very fast optics like the 50mm I don't see the advantage of a 6D over an 800D other than a larger FOV and all the functions you have available at daytime. If someone wants to shoot at higher ISO for some reason like a slow scope and a poorly tracking mount the 6D would help a lot. Looking at the bent DR curve I doubt it makes any sense. I don't know if it can be used at 200 or even 100. The 6D is better at ISO 400 but not much. I try to stay below 100 that's why low ISO is what I seek. I prefer to shoot longer subs because my computer cannot handle thousands of subs. Not a surprise because they use a lower bias for ISO 100 and 200. The 800D works well at ISO 400 but cannot be used at 200 (banding). My experience in astro is that the 600D works best at ISO 800, DR is 7 f-stops. The dynamic range at high ISO is high, the noise is low. the 6D is a low light performer in terms of regular night or available light photography.
