Darkstar Posted November 20, 2017 Share Posted November 20, 2017 The end result of a telephoto shot should be a clear image that is usable with Alamy and perhaps of a big enough file size to upload to my Saatchi Art pages for photo sales that have significant 'room size'. For this they are asking for around 36 meg. However, I am being told by camera shops that the best replacement for my Sigma 150-500 which is soft at the 400-500 end and does not take kindly to a 2x doubler, is the new Sigma 150-600 sports which is £1250 or so. With my current telephoto lens and camera, a buzzard at 5,000 feet comes out at 167k. Not 6 megapixels! https://www.dropbox.com/s/wdsw4rwjp9q55aw/Cloud of birds.jpg?dl=0 https://www.dropbox.com/s/bhmzmtfxqk863je/Buzzard feather detail.jpg?dl=0 https://www.dropbox.com/s/ndt5382ghk0kjgy/Buzzard soaring.jpg?dl=0 Does anyone think that mounting a Nikon D800 on a Questar Cadiotropic telescope would be a better bet for far distance bird shots? Has anyone tried using a telescope rather than a big lens for wildlife? cheers David Link to comment Share on other sites More sharing options...
