For exposures of 10 min. or more at these magnifications, it's necessary to guide the mount much more precisely. Shooting location was a suburban hilltop not far from home. Definitely looking forward to my next trip to a location with even darker skies. Adapter Tubes. If you wish to use converter lenses and/or filters, an adapter tube is required. To the best of my knowledge, there are a number of commonly used and frequently mentioned adapters; however, this section will only discuss the Pemaraal, Yoshida and Chen versions.
Click on the adapter tube name for more details. Before You Mount an Adapter Tube ..... Before you can use any adapter tube, the lens ring and lens hood must be removed from the lens barrel as shown below. This exposes a male thread for the supplied lens hood. An adapter tube has two female threads. The rear one screws on to the lens thread, and the front one is for converter lenses, filters, and other lens accessories. The Use of Filters Since the filter thread sizes of these adapter tubes are commonly used ones, filters can be added easily. A Few Notes Which adapter should I use? Welcome to Raynox.
Sigma 500/4.5 EX HSM Review. For a long time I worked with a couple of Sigma long lenses most of them were Zoom lenses, such as the Sigma 100-300/4 HSM (which I still have) and the Sigma 50-500/4-6.3 EX DG HSM. The lenses were good , but I always had the feeling that I needed more reach. So I did some research and it was clear that I would need a fixed-focal Lens. There was not much choice for my kind of budget ( <3.000 Euro). So I ended up with a used Sigma 500/4.5 EX HSM for my Canon camera bodies. Meanwhile I shot thousands of images with this Lens and I decided to make a short review of it, as I received quite some questions regarding the lens and its performance. The lens weighs around 3.2kg and is 35cm long without the lens-hood attached to it, which makes it very compact and lightweight compared to similiar lenses such as the Canon 500/4L. 4m - 8m 8m - infinity full In the last years I shot thousands of images with this lens and I'm still pretty happy with its performance.
