Are lens converters good

Well said Sanjeed! There is no point having gear that inhibits your photography by making things too heavy or difficult to manage.

It is for this very reason that I have owned a mm for so long, instead of a mm. It gives me framing versatility. If I know what to expect and have a prime to cover it, I can get the best possible image quality. Even a good zoom like the Sony FE pairs well with a 1.

So that lot offers a focal range of mm to mm and in a compact package. With an A9 the low-light AF is surprisingly good even with the 2x TC but yes, you pay for it with losses in speed and subject isolation. What are your thoughts on this, is there a maximum f-stop for certain teleconverters, it is never given? You need to check which lenses work with TCs by looking at the manufacturer specification, or specifications provided by the maker of the TC if that is different.

But either way, I still think you are thinking about this in the wrong way. Light is gathered at the front element of a lens and focused towards the rear. The reason you lose a stop of light, or two stops with 1.

Magnifying that part of the image to fill the full frame. So what you lose out on is the light gathered by the front element around the edges. It has nothing to do with small the optics are at the rear of the TC. Make sense? Howe does the canon mkii work with the 1. I assume the 2x would not work well with the zoom.

Also, you indicated the quality of the teleconverter is less significant for final IQ, but you do reference the canon mk iii converters. Is there much of an improvement in the mk iii vs. The difference is in the electronics. As for performance of the 1. Based on my experience with the older, series II EF 1.

I have both of the chipped and the chipless adapters, I tried the TC without any lens and it seems, the newer, much better teleconverters are much more sensitive, regarding to the written compatibility.

Only the officially allowed lenses are compatible. You cannot make any photo any other combinations. I could make photo with the combination of the chipless M42 adapter and the EOS 7DMk2, but without the teleconverters. The LiveView is working, the video is working, the photo mode is not. The big help would be a kind of Error 01 code hacking. These tiny glass tools are really great and saves me from carrying enormous tele lenses for my wildlife photography.

Another way to evaluate the effect of extenders on image capture is increasing pixel sampling of the primary object in a captured frame. I encountered this perspective in learning more about managing diffraction after acquiring a new high-pixel, full-frame camera and and more compact, lighter telephoto lens with a smaller aperture.

Previous use of a 21Mpxl camera with wide-aperture lenses kept this factor from affecting my image capture workflow. The bottom line of sampling theory is more pixels on the primary subject in an image provides more headroom to post-process images, compensating for diffraction, movement and noise.

Higher-pixel count sensors do this, but extenders increase pixel density regardless of sensor size. While there are many considerations in producing a final image, this is an approach to reduce concern regarding extender impact on image quality and focus on the other artistic characteristics desired in the published output. This is merely a summary, not a complete exposition or comprehensive discussion, but i found the reminder of sampling theory useful in determining how far to push into the diffraction zone with smaller aperture telephoto lenses with and without extenders.

I was thinking of getting an extender for greater flattening in landscapes. Would you recommend the 1. It also eliminates the vignetting issue which would result from using a DX lens on a FF camera.

And AF still works. Good to know. Your email address will not be published or shared.

In my case, I am looking to get some extra range on a camera where I dont have the option of another lens. Oct 25, 5. Messages: 6, They only front end converters that were any good like the 35mm and 80mm for the Retina and some other German 35mm range finders and SLRs, the front element of the 50mm standard lens comes and the converter is attached, but the others made from lower end rangerfinders in my limtied experance were not very good at all. Oct 25, 6. The only converter I have found to be anywhere near good was one for my long gone manual focus Nikons.

Mind you that was an AF adapter so I should have kept it. It was brilliant when coupled with a AI telephoto.

Oct 25, 7. Messages: 8, The canon and Nikon 2x converters are good, they aren't as good as just the glass, but for the price Oct 26, 8. Messages: The Vivitar "macro-focusing" teleconverter, is a high quality 7 element one.

As is the Kiron MC-7 model. Oct 26, 9. What do you think? Do you use teleconverters and do you think they are a good solution? Tell us in the comments. Dunja Djudjic is a writer and photographer from Novi Sad, Serbia.

Given the 2x crop factor already inherent in the MFT format, this can produce some extremely large effective magnifications. Note that the Olympus M. Compatibility: Olympus M. Magnification: 2x Aperture reduction: 2 stops Construction: 9 elements in 4 groups Size: Panasonic now makes two distinct camera ranges, and while the brand is the same, there's no crossover in the lens mounts.

Panasonic's Lumix G cameras have two teleconverters of their own — they can't use the Lumix S teleconverters or lenses at all. Magnification: 2x Aperture reduction: 2 stops Construction: 6 elements in 4 groups Size: 58mm wide length not quoted Weight: not quoted.

Considering this is the newest full frame mirrorless lens mount of all, Panasonic has done well to push out two Lumix S teleconverters — and the combined might of the L-mount Alliance pays dividends here as Sigma has produced two of its own.
