Yes and yes.
....but no, not for me. Teleconverters do exactly as you mention, they increase the reach by the X number, so 1.4 converter makes a 70-300 lens (for example) a 98-420. Brilliant you may think!..........but no, not so. Firstly, it's extra glass for the light to pass through, so you will loose a little sharpness, secondly, it's extra length for the glass to pass through, so you loose light. If you understand aperture and f-stops then basically, depending on the X rating of the teleconverter, you will lower maximum aperture, higher f-stop. In the case of the 1.4 that you mention, I believe you lose a full f-stop. The bigger the magnification, the more stops you lose. Now, if you are using a "Fast lens" (which is one with a low f-stop/large aperture) then you should be ok, but still will loose quality, if you are using a slower lens, you will probably end up with a lens that has a maximum aperture that is too small for auto-focus to work, usually anything lower than f/8 (which is why the lens is always fully open when the shutter button isn't pressed). I have a 80-200 f/2.8 lens. A "Fast" lens and I did have a Kenko x2, it worked ok, but just ok. I wasn't happy with the results and have since sold it and just stick with my 300 and get closer until I can afford a reach of 400. So to sum it all up, they are ok as a compromise, but you need a "fast" lens to start with. Craig Rogers 2007 Puma 110 XS 2011 Evoque Coupe Dynamic Lux www.craigrogers.photography |

Sorry Mike, but you are generalising there. I agree that a lot of amatuers don't invest in knowledge over equipment and that's possibly the majority, but tar and brush springs to mind.
There's a distinction between amateur photographer and someone who wants to take good photos. As for professional builders, that's a great example! Most professional builders are cowboys and a DIY'r is probably much better and I'm speaking from experience too after recently fully renovating an old farm cottage. ![]() I agree that an expensive lens doesn't make you a good photographer, but a good photographer will benefit from an expensive lens.....in certain circumstances. Take photo of a bird on a branch for instance. Take it with a lens zoomed out to 300mm at f/5.6. Photo becomes flat and everything is in focus. Get a little closer at 200mm with f/2.8........ Very different photo that you can't acheive with the cheaper lens. Then you have different types of photography, you sound like you do a lot of studio work and yes, lighting tecnhiques are crucial and an art form. However, if you're in the bush trying to photograph a Lion, you need to work with what you've got and move around. You can't really start looking at phase 3 lighting.

Thanks Craig, I'll steer clear of a converter lens for now.

agree completely on the tele converters, they ain't cheap either and were with all but top class objectives a disappointment for me
For those looking for reach and tele but not ready to spend a couple of thousand on a worthy fast objective you might want to google digispotting spotting scope + dslr or even bridge compact seems to do it that will be the next step for me ![]() |

![]() ![]() ![]() ![]() I love this site. So many people from so many backgrounds with a whole wealth of knowledge. I have been searching........ and as mentioned above I don't want a 1 lens does everything. I am vehicle bound so having a few in a peli case under the back shelf isn't a problem. I am looking at investing in the 18-70mm or 18-105mm, and then a 70-300mm which I feel will compliment the 50mm f1.4 and provide me with a means to photograph the majority of possibilities. I have always been keen on taking photographs and love it when I look at a good photo and it brings back a million memories. I also LOVE my (now dead) Sony Ericsson 5mp phone camera so will be buying another before setting out- it is just so convenient to take happy snaps at an instant. I have found a few lenses (all Nikon) and they all the DX VR range so quality and compatibility will be off the highest- but budget doesn't let me buy new so it will be a good second hand- it isn't my job so can't justify a big spend........ plus my ability probably won't make a whole lot of difference between a £500 lens and a £5,000 one. Plus the vehicle prep is costing me more than enough anyhow ![]() Glyn ![]() ![]() |

Glyn, glad the info was useful and I would say your 18-70 and 70-300 combo would be ideal.
You could try this site as its an excellent resource for the best prices: http://camerapricebuster.co.uk/ Also seen this one that trades in secondhand gear: http://www.mpbphotographic.co.uk |

That is the exact lens I have been using along with a Nikon 17-55mm ED DX. It is awesome but weighs a ton, and as mike has mentioned- will attract MANY thieving eyes. AWESOME though, easy to use and very sharp- the frog picture above was taken with it ![]() Glyn ![]() ![]() |

Glyn,
check out http://www.dpreview.com/products/Nikon/lenses good site, good info i don't remember exactly but think the 18-70 was not as well reviewed as the 18-105 (same class, not talking about the 15-55 2.8, which is a brilliant piece) also does not have VR. I liked the extra stretch to 105, its a really useful range. I also like my lenses to overlap a bit, gives you the extra reach both in and out. Also remember that lenses tend to work best in their middle range, so my 18-105 is worse at 105 as my 70-300 at 105mm etc and "generally" a 18-70 will be worse at 70mm than a 18-105. They also have the 18-135 but again i think it was not as well reviewed.(too much glass is never good) Oh, and when you go shopping, fix your budget and go from cheapest to your limit. No sense in taking an out-of reach top glass first as all others will seem disappointing.(ask me how i know, but its a common trick when selling optics. You know the customer wants to spent 100, you give him a 500 worth "just while you are here" teaser, and he'll walk out with a 250 piece) oh, and keep posting the frogs! ![]() |

Almost, this new one is to replace the old 80-400mm which is very outdated now and has a slow AF compared to a modern lens. I'll be in New York at the beginning of May and the US price is £800 cheaper for this new version. I don't normally buy a foreign model due to warranty, but at £800 cheaper.......... ![]() As for the choice of lenses, perfect. You'll also find the 70-300mm a great lens, smaller, lighter and much faster AF than the 400 you've been using.

I am slowly finding out that lenses are like Land Rovers and Ifor Williams trailers........ if it is in good condition it commands a vary high price

I have been an amateur photographer for 20 years (or so) upgrading and changing my camera every so often as and when what I think a great innovation comes along. I'm not trying to make a living from it and neither do I try and make money from it I just enjoy taking photographs. I am lucky enough to know pro-photographers as well as a group of amateurs.
I have just bought a Nikon AF-S 28-300 and a Nikon AF-S 50mm f1.4 to go with my new camera ... hopefully these will keep me going. I am looking forward to my next trip on the Salisbury plains with my new camera sometime in March Last edited by bpman on 28th Apr 2013 6:47pm. Edited 2 times in total |

And this is my point. You're showing a lack of understanding of lenses I'm afraid. If you want a shot with a nice blurry background it has nothing to do with the quality of the lens. It's about geometry; the position of the subject being shot versus the background versus where the shooter is plus the focal length. And 300 mils is closer than 200 mils so your whole statement about 300 vs 200 is just plain wrong I'm afraid. You can get the same blurry shot with the subject in focus with both of the lenses at the apertures you mention, it just depends on where you are positioned. You can also get that same shot with a 24-70, a fixed 50, 80 etc, pretty much any lens in fact. Ok it's harder with some than with others, and I could bore you to death with how a lens is constructed but it won't make any difference I suspect. One problem in the industry in general is so many weekend shooters who just think they know it all (yes this is directed at you) and when a photography question comes up on a forum everyone with a camera is an expert, and few if any will actually even bother listening to what a professional has to say. It is FACT that Glynn does not need more than one lens to do what he wants to do and get some great images, but rather like modifying landrovers, if he WANTS different lenses then that's fair enough. The trouble is that as before, too many amateurs spend too much time ![]() I think I'll bow out of this now otherwise I suspect I'll just end up ranting at the screen. |

Yet again, you're is missing the point, but feel free to shout at the screen, we can't hear you!
![]() I was simply talking about Dof with a high aperture along with creating Bokeh. All I was pointing out was that if I take a shot with higher aperture, I will generally get a nicer image (from blowing the background), nothing to do with the "Quality" of the lens, simply the more expensive lens has a lower f-stop, giving a better image in that scenario, so the money spent is on getting a faster lens. I wasn't trying to use the figure of mm as any reference, just pointing out an example of why I have to do as due to cost, I've only got a 70-300 f4.5/5.6 so changed to my 80-200 f/2.8. The f bit is the argument, not the length. I can see how you got the wrong end of the stick, what I perhaps should of included was I would use both lenses at 200mm which would of been a better example of aperture. You state I can get the same DoF with a 200mm lens at f/2.8 as I can with a lens at f/5.6?????? Not a chance! Slightly different example; Ask any pro wildlife shooter why they still choose to shoot with a 600mm lens when they could get closer to a subject. Construction of image, nothing to do with requiring the reach of a long lens. I was once out with a Pro, photographing Hares boxing. It was a bright sunny early morning in the golden hour just after sunrise, sun was low, over my shoulder meaning the eyes of the Hares where open and large (requirement for any good wildlife photography is the eyes). I could get close enough with my 300mm at f/5.6, light was so good, I opted for f/8 which this particular lens (like most) is sharpest. However, I didn't like the DoF, too much of the field was in focus, so I pushed down to f/5.6. Was the image good, it was ok. However, the pro, was a long way behind me with his prime 600mm. His image was gorgeous? Why? The equipment! The DoF was just perfect. A 500 or 600mm lens has such a small DoF that it allowed him to create a stunning image with both Hares in perfect focus and everything else around it blown out. I could not re-create that image with my equipment. Fact. Doesn't matter if I move around, get in closer (which obviously I can't as they'd just run away), the limitation of the lens does not enable me to get the shot I want. Same goes for a studio shooter, using a 200mm lens for photographing models from a distance rather than getting close up with a smaller lens it constructs a very different image of perspective. Here's another scenario for an amatuer spending money on kit..... I want to take photos of an owl in flight at dusk. Can I do that with good results with a cheaper slow lens? Yes, but by ramping the ISO right up! If I don't want to do that I need a fast lens. Unfortunatly, that costs..... ....and lastly, one more example. I want to go on a Svalbard photography expedition, however, I'd be wasting my time and money, why? Equipment, simple as. The minimum reach you need for such a trip is 400mm, anything less and you won't get the photos you're looking for. Why? Polar Bears think photographers taste nice.......... Stupid thing is, I agree with most of the things you say, but you still shoot me down with your upper echelon I'm also now bowing out of this as we are obviously not worthy in the eyes of a pro. ![]() I find it quite condescending that you look down your nose with the whole subject just because you are a pro. I know exactly how a lens is constructed thank you very much. I didn't say I'm an expert, I'm not, just giving information of what I know of my experiences.
