Why bother?

Thanks David :D I need that support! It seems to me that points being made by Alan (for example) are not really supporting the need for longer focal lengths on FF, but rather the need for more focussing aids such as a higher viewfinder magnification. If 300mm is long enough for the subject but on FF...

Hi , I am back after 3 murders in the deadliest county of England. I have come to the conclusion, that everyone has some positive input and thinking about it, there are for and against all the arguments brought by all the forum members on this topic. I'll have a nice sip of Courvoisier Cogna...

Why bother?
The higher number of mp is only one aspect of the IQ equation. Your FF owing friend can content himself that he doesn't need that massive 500mm monster after all! My FF friend cannot afford the 500mm f/4 - but it is exactly what two lecturers at our club recently (both pro photographers - one on spo...

Why bother?
What I don't understand is why the reference to the 35mm is given on a lens which is specifically designed for APS-C. Why would anyone give a hoot what the lens would be on 35mm if it is and can only be used on APS-C? I might give a hoot if someone can kindly answer this question for me. Back in...

Why bother?
If you used a 100mm lens with your film camera, why not use an other 100mm lens. one which is marked 100mm, because it is not usable for film and because it is specially made for APS-C. The problem with this is that you'll have to stand farther back if you want the image to occupy the same amount of...

I love my 135mm prime for Portraits. Sure, I'm standing back a bit, but the perspective is beautiful as is the oof background at f2.8 or f4.0

Anyone using FF WA lenses?
I must admit, I have shied away from buying any 'aps-c' glass since getting the 18-35 with the camera ... My only other new purchase has been the Samyang 14mm, with a FF image circle. In the back of my mind was its future use as an ultra wide on FF ... The other lenses are all FF by default purely...

which lense next
Put both your existing lenses in to the cupboard and purchase a Pentax-F 35-70mm lens for about 40 Dollars on Ebay or whatever the English prices are. This lens is superb and if you need a wider angle, move back. If you need more tele, move forwards. Gives you some exercise to and makes you a...

Sigma 18-35 f1.8
I received mine yesterday and have only done a few test shots with it, but it's pretty cool being able to focus and take shots when it looks pretty dark. I am doing a shoot on Saturday and will probably use it most of the time, I could see it becoming my standard lens and replacing my Tamron 17-50...

Sigma 18-35 f1.8
There are one or two reports that I have read that people had difficulty in getting focus as all focal lengths and at infinity with this lens. Mainly Canon users were involved so the Pentax mount might not be affected in this way. There is an optional USB dock with software which enables the user ...

Sigma 18-35 f1.8
Being sharp wide open right out to the corners doesn't sound like a recipe for exquisite portraits (even if you could find a flattering angle this wide), but it might be a great wedding lens or evening events. still waiting for our guys to report back.... ;)

18-135mm or 18-55mm ?
I find the 18 - 135mm DA WR excellent, good colour rendering, quiet and quick DC motor. It can show a slight vignette mid range in high contrast images, easily corrected. Obviously not particularly fast apertures above 35mm where it starts at F4.5. If you like manual use it's not a good choice as it...

18-135mm or 18-55mm ?
I have an 18-135 and a 17-70. The 18-135 pretty much lives on the camera nowadays. It does have some distortion, and some vignetting, but I can live with that. It is fast to focus and quiet, and has a good range. Not the best lens every produced by Pentax true, but I am more than happy with mine. ...

Tamron 70-200mm just arrived and at very good price
I've been using my Tokina 80-400mm ATX F4-5.6 since 1998 and it has served me well at airshows etc with its incredible reach. I have never been entirely convinced of its clarity however which always seemed very variable and it clearly suffers from significant purple fringing on trees etc at the lon...

DA 18-135mm WR
Hmm.. I'd been tempted a number of times but I've always chickened out at the final click :( I've pixel peeped people's shots on Flickr - the boring full size ones of uninspired streets, tedious landscapes, back yards, weddings and animals, not the hand picked, oversharpened, downscaled and pp...
