Sigma 300mm f2.8 APO EX DG HSM For Canon Digital & Flim SLR Cameras

Product Information

I was forced to buy a Nikkor 300 2.8 as well for an important assignment, which was an unwelcome added expense. Thought i would share this with you. I have had the sigma 300mm f2.8 in the service center 3 times now. finally with a new chip that the dealer here can reprogram it is really giving me shaaaarp images. If you buy this lens i highly recommend you get it calibrated with your camera and the new chip installed. A world of difference for me. I am so amazed at the images at 2.8, wide open It is just incredible. Now i cannot tell the difference in wide open and stopped down. And i am a crop every image heavily. Also i had to quit using the sigma 1.4 and 2.0 t.c.. It degrades the images fo much for me. In conclusion, I really like this lens, very competent for the price and a sleeper in this segment in my opinion. These were all taken stopped down a good deal, unlike most all the shots taken during my Tanzania outing which were mostly taken at or near wide open. With 1.4x APO Tele Converter, AF can operate between infnity and 1.2mm. If the subject is closer than 1.2m, only MF is available.

What do you suppose is one of the most the unappreciated parts of photography world? To me its third party lenses. Sigma, one of the best in the group, has been doing a lot of work to prove third party lenses are comparable, if not better then lenses from Nikon and Canon. Sigma has made a heavy lens remarkable. This lens is for the photographer that can’t get to their subject, but still need their frame to be filled. Canon changed mounts completely between FD and EF. While EF lenses focus perfectly on their mirrorless adapters, older lenses can't even mount. And, that's not even considering the limited compatibility of EF-s and EF-m.Nikon's F-mount underwent several iterations with limited inter-compatibility. Pre-Ai, Ai, AF, AF-D, AF-I, AF-S, AF-P. And now, the entirely different Z mount. Nothing prior to AF-S can autofocus on their mirrorless cameras even with an adapter. You’ve posted so much other garbage in here since you made that comment I wouldn’t have even seen it in your posting history. In summary, good results on average, but you don't see big gains through stopping down. As well, the Sigma magic doesn't seem to come through on this sample of the lens; there isn't an aperture setting which provides extraordinary sharpness. This lens is sharp depending on the subject distance. I found it is not that sharp when the subject was over 150 feet away. For a telephoto lens I did not like working with subjects at a great distance. Color Rendering and Color Fringing Considering a given generation of build technology and similar image quality the longer the lens the smaller the gap of weight btwn a x-y mm zoom and a y mm prime.

Sigma 300mm F2.8 APO EX DG HSM: Digital Photography Review

Would I consider owning the Sigma 300/2.8 HSM EX with a set of matching Sigma EX teleconverters myself? As I sit here in front of my PC writing this, I'm scheming on how to make just that happen! The aspect we are commenting about, is it not very clearly described in this official press release? Here are some sample images where I have used the Sigma 300 f2.8 and a non reporting 2X Kenko converter which is not as good as the Canon 2X MkIII converter.Lenses aren't purely about sharpness of course, but the Sigma does extremely well in all respects. Chromatic aberration is visible at 120mm, but diminishes to nothing at 300mm. Vignetting is nothing to worry about, at a maximum of 1.4 stops wide open at 300mm. Distortion is well controlled too: it's essentially perfectly-correctedat 120mm, but there's a little pincushion distortion at 300mm. As for weather sealing, it is also nice that Sigma is finally including a rubber gasket at the lens mount to prevent dust from entering the camera body and the lens. The gasket is pretty short though, so I hope Sigma will make it a tad longer in the future, similar to what Nikon does to make it more useful. The lens barrel itself is nicely made and will take on some beating and weather abuse. I am not sure if it will withstand a lot of rain, but I have used it in light rain without any problems. I believe this is one of the first Sigma lenses to get weather sealing (along with the new 12-24mm and 150mm f/2.8 macro lenses). stop matters a lot. 100-400mm is too dark with 1.4x TC. With the 400mm f4.5 I still have a very usable 560mm f6.3 which is also much lighter and smaller than my massive 200-600mm.

failures like that are why three of the biggest press agencies in the world left canikon for sony, they took all of their sports shooters with 'em. The filter holder is intriguing. The filter is circular and you screw it on as you would a normal circular filter. The difference is the 46mm filter went inside the body on the lens. The filter is not there to be cool, more as a bit of pleasing engineering. Basically you do not have to buy a filter to fit the ~119 front of the lens. That saves a bit of money. Pentax 300mm ƒ/2.8 ED IF SMC P-FA - but this lens has been discontinued. Instead they offer a ƒ/4 version, which is smaller and less expensive. The lens uses Pentax's SDM autofocus technology. Lens construction - 11 elements in 9 groups, including two Extraordinary Low Dispersion glass elements (Abbe number 90.3) The most frustrating thing I experienced was an incredible bird in the middle of a field. Out of about 10 shots, only two maybe three had critical focus. I couldn't understand what was going on. Happened a few times; mostly with birds. Here's the best of the series:You can bet that any new Sigma super tele would be way more expensive than the old Sigma 120-300mm f2.8 also. Inflation has been very high overall, in particular the price of raw materials. My bet is at least double the price. Then came the Z generation of Nikon super teles that match the weight of Canon and Sony lenses although they embed a TC. The new 300mm F2.8 G Master OSS lens will take inspiration from the Sony’s other G Master telephotos, such as its 600mm F4 G Master OSS and 400mm F2.8 G Master OSS, both of which we’ve found to be incredibly fast and sharp, as is to be expected from Sony’s high-end G Master lineup. The Sigma 120-300mm F2.8 DG OS HSM S has a Custom Mode switch with three settings - Off, C1 and C2. Much like the Custom Settings on a camera body, you can use the provided software to tailor the lens settings (AF speed, focus limiter and OS functions) and then save them to the C1/C2 modes for easy recall via the Custom Settings switch. Also not all fancy a a lens of the the seize and price of a 400/2.8 and weight of a 600/4 or said in another word a€12.000 and 3kg lens.
