As promised, here's a few pics I shot this week while testing my new (used) Promaster 1.7x teleconverter. In a previous thread, someone had said (Bob R I think) they hadn't heard of "Promaster", so just for the record, from what I understand Promaster is one of those "house generic" brands like Quantaray from Ritz/Wolfe. Also to summerize, I purchased this particular unit off Ebay for $38 after discovering that Canon TC's don't work with Tamron and Sigma lenses (and not even all Canon lenses...thanks again Bob!).
Before I get the pictures up here, I do have a few comments to make... While this TC is supposed to be
AF, I could not get the auto focus to work on either lens with this TC...aka I was running stricktly on manual focus. Beyond that, while I didn't have any other problems using the TC with the Sigma lens, I did have a few problems using it with the Tamron...mainly in regards to aperture. Basically when I first fire up the camera, I have to have the aperture set at f4.0 otherwise the camera error'd out when I snapped the shutter (i.e. if the lens was zoomed in and defaulted to f5.6, then the camera would error out, so I had to zoom the lens all the way out, set the aperture and go from there). I could adjust the aperture after
I got it set up, but I had to start at f4.0. I'm not sure if this is typical of TC's but I thought it was kinda freaky. Basically it works and as you'll see from the pics, it works pretty well, it just takes a little fudging to get it to do what you want it to do.
The first three pics were shot using the Promaster 1.7 with my Tamron 70-300mm macro and the fourth image was shot with the Promaster and my Sigma 17-50mm. Camera used was, of course, my new Canon Rebel XT and all the pics were shot handheld. Additionally, on the first three pics, I used my Metz flash (without a diffuser) so some of the highlights are a tad hot. Please note: these images are pretty much "as is"...with the exception of some RAW processing, they are as they came off the camera...no sharpening, etc.. Also please be aware that due to the TC, the EXIF data on these images is NOT nessacarily correct (and I wasn't really taking notes...sorry). Also please be aware that since I was considering this an equipment test, these pics aren't really up to my usual artistic par...i.e. I wasn't really worried about composition or anything for this set.
All shots were taken at the nature center where I volunteer and should anyone wonder, yes, I was in the cage with these animals, not shooting them thru "the safety of a window" or from outside the cage.
This certainly could have been a better shot and I'm sure I could "tweak it" in PS, but for this test, again I wasn't really worried about asthetics as much as portraying what the equipment is capable of.
I think this shot really shows what this TC is capable of. A $38 TC and a $90 lens? Really, how could anyone ask for more!
Well, as they say, "the proof is in the pudding". For the money, I really can't complain at all
. No this TC certainly isn't going to be "perminantly attached" to the camera...it's going to be a special occasion accessory when I need that little extra boost, but it certainly has potential to be sure. As already mentioned it is a little flakey and will require some extra patience to use and while I don't really know if this is indicative of TC's or not, either way I can live with it. Beyond any composition considerations, all of these images would be quite printable with a little pp and some USM, etc.. All and all, not a bad bargain at all!
On a stricktly personal note, after all of the negative stuff I've read about TC's in general both here and abroad, I'm not really sure what all the fuss is about. If I can get pics like these with a "cheap" TC, I would think having a decent one would be a real pleasure. I dunno...for folks like myself on a really tight budget, anything that gives me a little extra edge is always welcome. I guess a lot of people are just spoiled (LOL!!!).
Alrighty, that's it for now. Just so ya'll know, I'm going to be shooting my first wedding next weekend so between the prep and all the work I'm going to have to do afterwards, I'm probably not going to be around much for the next couple of weeks...i.e. don't get too concerned if I don't get back to anyone right way.
