ok, so I'm between two lenses right now and I've been lurking the internet a while now trying to figure this out so I thought I should drop in, say hello, and see what you all have to say.
so, to start I may as well note I'm using an a300 with the kit lens (18-70mm) and it's not quite doing it for me as I need to catch shots of birds. see, we have a lot of bird houses and feeders as well as trees in my yard so I need a way to get them without getting close and the 1870 isnt cutting it. I missed this great shot of a baby bird just learning to fly cause I simply could not get close enough (I didnt want to kill it over a photo by scaring it, and having it fall where it wouldnt be able to fly from).
so I've got it down to two lenses, the sony sal75300 and the sal55200. Biggest reason for picking the 75300 is simply it's zoom capability but I wonder if the CA wont interfere with my shots anyway plus it doesnt really meet or overlap my current zoom (I know it's not by much, call it ocd or madness, cause it's not sparta). So I did more research and picked out the 55200 lens. I understand from a lot of reviews that the CA occurs after 200mm on lenses that arent really built for the higher ranges (basically getting too wide a zoom range will result in the jack of all trades, master of none effect). Plus the 55200 seems to get a higher review score, and on top of the fact that it has a lower base zoom means I can pull back further without having to change lenses but I'm not so sure that will be any kind of a real problem for me.
anyway, these are the reviews I'm talking about:

also, I'm aware of the tamron lenses but the reviews seem to rate sony higher despite what most users say. I normally side with the general public over 'expert reviewers' but something about them being built using a lot of plastic (or so I've read) bugs me and I'm just overall more impressed with sony's quality over tamron's 6 year warranty. guess it's more of a comfort zone thing. I also have read about sigma's gear stripping too so I'm not interested in them so much either but tamron could win me over if they are really that good but I'd rather spend that little bit more and get that little bit more if thats the case.
oh and I'm on a budget so anything 300+ or so is sort of out of my reach. so stuff like zeiss and G lenses are too much for me.
well, hope thats enough for one post. I thank anyone that got through it. made a poll for those that dont wanna read and just want to cast opinion
. thanks in advance, hope you guys can shed some light for me.
edit: oh and I almost forgot. I also did my homework on the legendary beercan by minolta but for being a ~23 yo lens I can only find it second hand. I did find one for $144 on keh but it was the non AF version. all the others are nearing $300 so it's nearing my cap as well as the fact that you have to buy it second hand kind of turns me away from it. no warranty, and old for that price isnt really acceptable to me for any kind of lens.
