What are the tradeoffs when replacing two zoom lenses with a superzoom?
I'm after a zoom range of 28mm to 200mm. Budget is £600 GBP
The Nikon 18-200mm VR II has a decent MTF chart and covers the entire zoom in a single lens. I've no idea how good it is at focusing accuracy or zooming speed. I'd hope they were both good.
The Sigma 17-70mm f2.8-4 and Nikon 55-300mm look reasonable and cost only £500 for the pair. MTF does not look as good as the 18-200mm which I find very surprising. I always thought a smaller zoom range would offer better quality.
What recommendations could you give for good lens(es) covering that zoom range, given my miniscule budget? I may be able to stretch a little on the budget.
So my requirements are, a short lens perhaps 24-70 ish for normal everyday photos. And a zoom lens (180mm to 300mm) for Rugby sports shots.
